This application claims priority from Korean Patent Application No. 10-2023-0157324 filed on Nov. 14, 2023, which is incorporated herein by reference in its entirety.
The present disclosure relates to a vehicle lamp and a method of manufacturing a connector for the vehicle lamp, and more particularly, to a vehicle lamp and a method of manufacturing a connector for the vehicle lamp that allow for more secure installation of the connector on a film included in the vehicle lamp.
Generally, vehicles are equipped with lamps that serve the illumination function for more easily identifying objects around them during low-light conditions (e.g., nighttime driving), and the signaling function for informing other vehicles or road users of their driving status.
For example, vehicle lamps include headlamps that illuminate the front side of the vehicle to secure the driver's view, brake lamps that illuminate when the brakes are applied, turn signal lamps used when making a right or left turn, and reverse lamps that illuminate when reversing. Additionally, reflectors that perform the function of reflecting light to make the vehicle more easily recognizable from the front and rear are also mounted.
At least some of the vehicle lamps include heating wires (equipped for, e.g., defrosting the lamp surface), and there is a difficulty in mounting a connector on the film to supply power to the heating wires. Furthermore, during the manufacturing processes of mounting the connector on the film and injection-molding the vehicle lamp, manufacturing defects such as deformation of the connector may occur, necessitating a technique for improvement.
Aspects of the present disclosure provide a vehicle lamp and a method of manufacturing a connector for the vehicle lamp that allow for more secure installation of the connector on a film included in the vehicle lamp.

The first injection molding part may correspond to a light-guide plate, and the second injection molding part may correspond to an outer lens. The first mold may be provided on a fixed table, and the fourth mold may be provided on a transfer table configured to be translated toward the fixed table with the rotating table interposed therebetween.
According to another aspect of the present disclosure, a vehicle lamp includes: a film; and a connector having a housing disposed on a first side of the film, a metal plate disposed on a second side of the film, and a terminal coupled to sequentially penetrate through the housing, the film, and the metal plate. An end of the terminal that penetrate through the metal plate may be welded to the metal plate.

The film 100 may include a base layer 110, a light-blocking pattern 120, and a heating wire pattern 130.
The base layer 110 may be composed of a thin film formed of a transparent material. For example, the base layer 110 may be formed of a polycarbonate (PC) material.
On a first side of the base layer 110, the light-blocking pattern 120 may be provided to prevent light supplied from a light source from passing through at least some area. For example, the light-blocking pattern 120 may function to separate the area through which light passes into multiple areas or to partially limit the area through which light passes.
On a second side of the base layer 110, the heating wire pattern 130 may be provided. The heating wire pattern 130 may be formed on the second side of the base layer 110. Alternatively, a plurality of base layers 110 may be provided, and the heating wire pattern 130 may be interposed between the plurality of base layers 110. The heating wire pattern 130 may be formed of a copper (Cu) wire. For example, the heating wire pattern 130 may be formed in a zigzag pattern having a set distance between the reciprocal lines.
The light-guide plate 200 may function to guide light incident from the light source to be uniformly distributed in the direction where light is output. For example, a matrix of dot pattern 210 may be formed on the surface of the light-guide plate 200 where the light enters to more uniformly distribute the amount of light across all areas. For example, the dot pattern 210 may be formed in a conical shape inside the light-guide plate 200, but the shape of the dot pattern 210 is not particularly limited.
Additionally, the outer lens 300 may function to emit light that is incident through the light-guide plate 200 to the outside.
The light-blocking part 400 may prevent light from being emitted from at least one side of the outer lens 300. The light-blocking part 400 may also prevent light from being emitted to another side neighboring the one side of the outer lens 300. The light-blocking part 400 may be formed of a black or dark-colored material, or may be formed of an opaque material. The light-blocking function of the light-blocking part 400 may also be implemented through coating or deposition. The area where the light-blocking part 400 is formed inside the outer lens 300 may prevent the light emitted from the light source from directly passing through. However, the light that has passed through the light-guide plate 200 may be refracted as it reaches the outer lens 300, and may be indirectly emitted from the outside of the outer lens 300 where the light-blocking part 400 is arranged.

Referring to
Each of the plurality of grippers 500 may include a head member 510 and a lifting member 520.
As illustrated in
Additionally, the lifting member 520 may be in the form of a cylinder (e.g., a hydraulic cylinder) that can be increased or decreased in length. For example, the lifting member 520 may be configured such that it moves horizontally within a set range while it is being moved vertically. Thus, when being ascended, the lifting member 520 may also move outwardly from the edge area of the film 100. Conversely, when being descended, the lifting member 520 may move inwardly to press and fix the upper part of the corresponding gripping portion 111 of the film 100.
When the film 100 is fixed on the table by the grippers 500, deformation or lifting of the film 100 can be prevented during an insert molding process.
One or more guide pins 530 may be provided on the table to provide aid in mounting the film 100 in a set position. Correspondingly, the film 100 may include guide holes 112 into which the guide pins 530 may be inserted. The guide pins 530 and the guide holes 112 may be formed to correspond to each other in terms of position and number.
Additionally, referring to
The guide block 600 may include a contact surface 610, which faces the film 100, and a step 620, which is recessed from the contact surface 610 to be disposed at the same height as the film 100 when the guide block 600 is pressed along the mounting direction of the film 100.
When the guide block 600 is protruded from the table, the contact surface 610 may be disposed to abut the edge area of the film 100. In this case, since the contact surface 610 supports the film 100, the mounted state of the film 100 on the table can be maintained after seating the film 100.
Additionally, when the guide block 600 is elastically pressed into the table against a spring 630, the contact surface 610 may dislodge the edge area of the film 100, and the upper surface of the step 620 may be disposed at the same height as the lower surface of the film 100.
The table, the grippers 500, and the guide block 600 may be components included in a manufacturing apparatus 1000 (see
During the insertion and molding of the film 100 on the table, flow mark defects may occur in some places due to the high flow rate of the molten resin. Specifically, due to the high flow velocity of the molten resin, the black-colored light-blocking pattern 120 of
A gate rib GR may be additionally provided around the flow mark area WA. A molten resin may be injected into the gate rib GR, which may reduce the injection pressure and speed. Therefore, by injecting the resin through the gate rib GR, the flow mark area WA may be minimized. The gate rib GR may be disposed adjacent to a first injection part 1110 (see
The gate rib GR may be provided inside the first injection part 1110, and as the molten resin is injected through the gate rib GR, the light-guide plate 200 may be molded. In an embodiment where the outer lens 300 is molded first without molding the light-guide plate 200 on the film 100, the gate rib GR may also be provided at the part where the molten resin for molding the outer lens 300 is injected.
As the resin is first injected through a gate G, disposed in the center area of the gate rib GR, and the molten resin fills the inside space of the gate rib GR, a flange area FA formed on the side of the film 100 may be pressed. In other words, the molten resin injected through the gate G and the gate rib GR may press the film 100 while being supplied, and as the area for supplying the resin through the gate G and the gate rib GR widens, the supply pressure and speed of the resin decrease, effectively minimizing the flow mark area WA.
The fixed table 1100 may include a first mold M1. Additionally, the rotating table 1200 may include a second mold M2 and a third mold M3. The transfer table 1300 may include a fourth mold M4.
The fixed table 1100 may include a first injection part 1110 and a second injection part 1120 for injecting molten resin toward the first mold M1. The first injection part 1110 may supply a molten resin necessary for molding the light-guide plate 200. The second injection part 1120 may supply a molten resin necessary for molding the outer lens 300. The first injection part 1110 or the second injection part 1120 may inject resin through the gate rib GR.
Additionally, the second mold M2 and the third mold M3 may be disposed on both sides of the rotating table 1200. The second mold M2 and the third mold M3 may be selectively rotated to face the first mold M1 or the fourth mold M4.
The rotating table 1200 may move in the direction of the fixed table 1100. For example, the fixed table 1100 may remain stationary, and as the rotating table 1200 moves toward the fixed table 1100, the first mold M1 and the second mold M2 may face each other, or the first mold M1 and the third mold M3 may face each other.
The grippers 500, which press and fix the gripping portions 110 at the edge area of the film 100, may be provided in the second mold M2 or the third mold M3.
The transfer table 1300 may move in the direction of either the rotating table 1200 or the fixed table 1100. For example, the transfer table 1300 may move to be in close contact with the rotating table 1200, or with both the rotating table 1200 and the fixed table 1100.
The transfer table 1300 may include a third injection part 1310 for injecting molten resin toward the fourth mold M4. The third injection part 1310 may supply a molten resin necessary for molding the light-blocking part 400.
In the first step S100, the film 100 may be fixed by being inserted into the guide pins 530 during the mounting of the film 100 onto the second mold M2. Additionally, in the first step S100, the film 100 may be mounted on the second mold M2, and the grippers 500 may press and fix the film 100.
The second step S200 may include a sub-step S210 of moving the rotating table 1200 to be in close contact with the fixed table 1100 or moving the transfer table 1300 along with the rotating table 1200 to be in close contact with the fixed table 1100. In the second step S200, after the completion of the sub-step S210, molten resin may be injected through the first injection part 1110 to mold the light-guide plate 200. After the second step S200 is completed, the first and second molds M1 and M2 may be separated. In this case, the film 100 and the molded light-guide plate 200 may be positioned on the first mold M1.
In the third step S300, the primary rotation of the rotating table 1200 may be performed after the second mold M2 is separated from the first mold M1, with the film 100 and the light-guide plate 200 positioned on the first mold M1. When the primary rotation of the rotating table 1200 is performed in the third step S300, the rotating table 1200 may be rotated so that the third mold M3 faces the first mold M1.
After the third step S300 is completed, the fourth step S400 may be performed by bringing the third mold M3 into close contact with the first mold M1. In the fourth step S400, the outer lens 300 may be molded by supplying molten resin between the other side of the film 100 and the third mold M3 through the second injection part 1120. For example, the first injection part 1110 may supply resin from the central area of the first mold M1, and the second injection part 1120 may be disposed to supply resin from the outer area compared to the first injection part 1110. After the fourth step S400 is completed, the first mold M1 and the third mold M3 may be separated. In this case, the film 100, the molded light-guide plate 200, and the molded outer lens 300 may be positioned on the third mold M3.
In the fifth step S500, the secondary rotation of the rotating table 1200 may be performed so that the first mold M1 and the third mold M3 may face the second mold M2 and the fourth mold M4, respectively. As the rotating table 1200 rotates again in the fifth step S500, the area of the light-guide plate 200 may be disposed to be in close contact with the fourth mold M4 at the beginning of the sixth step S600 since the outer lens 300 is attached to the third mold M3.
The sixth step S600 may include a sub-step S610 of moving the transfer table 1300 to be in close contact with the rotating table 1200 or with both the rotating table 1200 and the fixed table 1100. After the sub-step S610 is completed, the light-blocking part 400 may be molded by injecting molten resin through the third injection part 1310 into the area adjacent to the outer lens 300 or the area adjacent to both the outer lens 300 and the light-guide plate 200.
Through the method S10, a vehicle lamp may be manufactured by rotating the rotating table 1200 equipped with different molds twice on a single table, thereby eliminating the need to transfer the product to another table and effectively reducing the process time. Additionally, since no product transfer between tables is needed, processes such as preheating during product transfer can be omitted.
The connector 2000 may be disposed on the first side of the film 100 to be connected to a power supply line, which supplies power to a heating wire pattern 130 (refer back to
The housing 2100 may be disposed on the first side of the film 100, and the metal plates 2200 may be disposed on the second side of the film 100. The terminals 2300 may be inserted sequentially through the housing 2100, the film 100, and the metal plates 2200, thereby fixing the connector 2000 on the film 100.
The ends of the terminals 2300 that penetrate through the metal plates 2200 may be fixed by welding on the outside of the metal plate 2200. The metal plates 2200 may be configured to be supported on the second side of the film 100 to face the housing 2100 from the film 100. Therefore, the housing 2100 and the metal plates 2200 may be securely bonded together through the terminals 2300 on a thin film, maintaining a stable connection.
With the connector 2000 mounted on the film 100, the light-guide plate 200 may be injection-molded on the first side of the film 100, and the outer lens 300 may be injection-molded on the second side of the film 100. However, there may be a concern that the housing 2100 or the terminal 2300 may be deformed from its set position or direction due to the injection pressure and temperature.
To prevent deformation of the housing 2100 or the terminal 2300, core pins 3100 may be inserted into the housing 2100 during injection molding. For example, the core pins 3100 may be inserted into the housing 2100 to be in close contact with the inner bottom surface of the housing 2100, with at least two core pins 3100 inserted.
The core pins 3100 may be provided on a support mold 3000 that is coupled to the housing 2100. For example, at least two core pins 3100 may preferably be provided. When two core pins 3100 are disposed side by side, they may be inserted along whichever of the left-right and top-bottom directions of the housing 2100 is longer. For example, as illustrated in
The housing 2100 may also include a contact piece 2110 that contacts the first side of the film 100 and a coupling piece 2120 that is provided outside the terminals 2300, such that another housing (e.g., a connector housing) of a power supply line may be coupled thereto.
The contact piece 2110 may be provided with a concave or convex pattern along the edge area where the light-guide plate 200 is injection-molded. When the light-guide plate 200 is injection-molded, a convex or concave pattern may be formed in the light-guide plate 200 to correspond to the concave or convex pattern of the contact piece 2110. For example, convex portions 2111 may be provided along the edge of the contact piece 2110, and corresponding concave portions 201 may be formed during the molding of the light-guide plate 200.
The connection part 2310 may be an area exposed inside the coupling piece 2120 of the housing 2100. Therefore, when another housing with a power supply is connected, the connection part 2310 may be electrically connected.
Additionally, the penetration part 2320 may extend from the end of the connection part 2310 and pass through the film 100 and the housing 2100. In other words, the penetration part 2320 may be disposed inside the film 100 and the housing 2100. The penetration part 2320 may include one or more interference patterns 2321 in the area where it contacts the inside of the housing 2100.
The interference patterns 2321 may function to enhance binding by increasing the contact area between the penetration part 2320 and the inside of the housing 2100. The penetration part 2320 may be integrally formed with the connection part 2310. Some area of the penetration part 2320 may be formed wider than the connection part 2310.
The head part 2330 may be disposed at the tip of the penetration part 2320 to penetrate through the corresponding metal plate 2200. For example, two terminals 2300 may be provided inside the housing 2100, or alternatively, more than two terminals 2300 may be provided. Inside the housing 2100, two connection parts 2310 may be exposed, and a partition wall 2121 may be provided to divide the space between the two connection parts 2310. The partition wall 2121 may also contribute to preventing the deformation of the housing 2100 during injection molding around the housing 2100 and the film 100.
In other words, in the method S20, the housing 2100 may be disposed on the first side of the film 100, the metal plates 2200 may be disposed on the second side of the film 100, and the terminals 2300 may be coupled to the housing 2100, the film 100, and the metal plates 2200 by integrally penetrating them.
As described above, the film 100 may be provided with a heating wire pattern 130 on one of its surfaces that face the housing 2100 and the metal plates 2200. The position of the heating wire pattern 130 may be selectively changed. Alternatively, the film 100 may be provided with the light-blocking pattern 120. The light-blocking pattern 120 may be disposed on the other surface of the film 100 than the heating wire pattern 130, or between the film 100 and the heating wire pattern 130.
After the ninth step S900 is completed, the method S20 may further include a tenth step S1000 of welding the ends of the terminals 2300 that penetrate through the metal plate 2200 to the metal plates 2200. The tenth step S1000 may be performed by welding the head parts 2330 of the terminals 2300 and the metal plates 2200. The tenth step S10 may be optional.
The method S20 may further include an eleventh step S1100 of coupling the support mold 3000 to the housing 2100 after the tenth step S1000 is completed. In the eleventh step S1100, the support mold 3000, which is provided with at least two core pins 3100, may be coupled to the housing 2100 such that the core pins 3100 may be in close contact with the inner bottom surface of the housing 2100. In other words, since the contact piece 2110 of the housing 2100 may be deformed by heat during injection molding, the support mold 3000 may be inserted into the housing 2100 to press the contact piece 2110 from the inside through the core pins 3100, thereby minimizing or preventing deformation of the contact piece 2110. In the eleventh step S1100, the support mold 3000 may be coupled such that the core pins 3100 may be disposed parallel to the terminals 2300 positioned in a connection area 2130 formed inside the housing 2100.
The method S20 may further include a twelfth step S1200 of molding the light-guide plate 200 on the first side of the film 100 after the eleventh step S1100 is completed. In the twelfth step S1200, the light-guide plate 200 may be molded on the first side of the film 100 in the lateral direction of the housing 2100. As described above, the light-guide plate 200 may be molded to correspond to the convex portions 2111 formed on both sides of the contact piece 2110 of the housing 2100, and as a result, the concave portions 201 may be formed. Since the convex portions 2111 and the concave portions 201 have been already described above, descriptions thereof will be omitted.
The method S20 may further include a thirteenth step S1300 of molding the outer lens 300 on the second side of the film 100. Since the molding of the outer lens 300 has been described above, a description thereof will be omitted.
The method S20 may further include a fourteenth step S1400 of removing the support mold 3000 along with the core pins 3100 from the housing 2100. The fourteenth step S1400 may be included in the method S20, but the support mold 3000 and the core pins 3100 may be omitted from the completed vehicle lamp.
Therefore, by welding the head parts 2330 of the terminals 2300 on the metal plates 2200, the fixing force of the connector 2000 may be improved, and the connector 2000 may be prevented from being easily separated from the film 100.
According to the embodiments of the present disclosure, by rotating a rotating table equipped with molds of different shapes on both sides, different configurations can be injection-molded in one manufacturing process. Guide pins or guide blocks corresponding to the mounting area of a film are provided, enabling precise mounting of the film on the table. When injection molding is performed around the connector mounted on the film, deformation of the housing due to injection pressure and temperature can be prevented. Since the inside of the housing is supported by core pins provided inside the support mold, deformation of the housing can be prevented during the injection process through. Terminals are coupled to penetrate through the housing, the film, and the metal plates, and the head parts of the terminals and the metal plates are welded, allowing the connector to be firmly fixed on the thin film.
While the technical idea of the disclosure has been illustrated and described in detail with reference to specific embodiments, the present disclosure is not limited to the specific configurations and operations of these embodiments. Various modifications can be made within the scope of the invention without departing from its spirit. Therefore, such modifications should be considered encompassed within the scope of the disclosure, and the scope of the disclosure should be determined by the appended claims.
