[0002] This application claims priority and benefit to Korean Patent Application No. 10-2021-0093813, filed on July 16, 2021, with the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to a lamp unit and a lamp aiming device, and more specifically, to a lamp unit and a lamp aiming device that can simplify the lamp assembly process and improve assembly performance and operability. Background Technology

[0004] Vehicles are typically equipped with various types of lights that serve both illumination and signaling functions. Illumination allows the driver to easily identify objects around the vehicle when driving at night. Signaling notifies drivers in other vehicles and pedestrians on the road of the vehicle's status.

[0005] For example, vehicle lights may include headlights (or headlights) and fog lights for illumination functions, and turn signals, taillights, brake lights, and side markers for signaling functions. Regulations specify the installation standards and specifications for these vehicle lights to ensure they function properly.

[0006] Among vehicle lights, headlights offer low beam or high beam modes to ensure the driver's forward visibility when driving at night. Headlights play a very important role in safe driving.

[0007] Meanwhile, if the headlight beam direction deviates from the initial set direction due to vibrations or impacts generated by the vehicle's movement, it may cause light blindness or impaired vision for drivers in vehicles ahead (or oncoming vehicles). When the headlight beam direction deviates from the initial set direction, it is necessary to perform an aiming operation to adjust the headlight beam direction back to the initial set direction.

[0008] The aiming operation of the headlights can be performed by rotating the aiming stalk located in the engine compartment of the vehicle, rotating the aiming bolt that engages with the aiming stalk (e.g., an aiming bolt having a crown gear that engages with the aiming stalk), and rotating the headlight reflector together with the aiming bolt.

[0009] However, due to the nature of the headlight assembly process in the relevant technology, a separate support bracket is required to assemble the aiming rod after the aiming bolt is tightened, which complicates the assembly process.

[0010] In other words, the aiming bolt needs to be rotated and tightened at a sufficient speed so that the aiming bolt connected to the lamp module can be positioned at the predetermined tightening completion point. However, with the aiming bolt and aiming rod engaged, the aiming rod needs to be rotated to rotate the aiming bolt. Furthermore, it is difficult to fully rotate the aiming bolt by rotating the aiming rod. Therefore, after tightening the aiming bolt, the final step requires additional assembly of the aiming rod and the support bracket used to support the aiming rod (using fastening bolts to secure the support bracket to the lamp module). As a result, in the final assembly line (the production line where the headlights are assembled to the body), there are problems with assembly performance, operability, and reduced productivity.

[0011] Furthermore, in related technologies, it is difficult to provide the aiming rod and support bracket as components integrated with the lamp module (e.g., headlight module), and the aiming rod and support bracket need to be provided and managed separately from the lamp module, which complicates the management and assembly process. Therefore, there is a problem of increased time and cost required to assemble the headlights.

[0012] Therefore, various studies have recently been conducted to simplify the lamp assembly process and improve assembly performance and operability, but the results remain insufficient. Thus, there is a need to develop a technology to simplify the lamp assembly process and improve assembly performance and operability. Summary of the Invention

[0013] This disclosure aims to provide a lamp unit and a lamp aiming device that can simplify the lamp assembly process and improve assembly performance and operability.

[0014] This disclosure also aims to modularize and provide aiming rods and support brackets in a state of temporary assembly with the lamp modules, and to simplify the assembly process in the final assembly line where the lamps are assembled to the vehicle body.

[0015] This disclosure also aims to eliminate the process of fastening the support frame with fastening bolts in the final assembly line, and to fully assemble the lamp simply by performing the task of pushing the aiming rod.

[0016] This disclosure also aims to reduce the time and cost required for assembling lamps.

[0017] The objectives to be achieved by the embodiments are not limited to those described above, but also include objectives or effects that can be understood from the solutions or embodiments described below.

[0018] An exemplary embodiment of this disclosure provides a lamp aiming device that controls an aiming bolt for adjusting the light emission direction of a lamp module. The lamp aiming device includes: an aiming rod configured to move between a first position spaced apart from the aiming bolt and a second position where the aiming rod engages with the aiming bolt; a support frame located on the lamp module for supporting the aiming rod on the lamp module; and a locking part configured to lock the aiming rod onto the support frame when the aiming rod moves from the first position to the second position.

[0019] This is to simplify the lamp assembly process and improve assembly performance and operability.

[0020] In other words, in the relevant technology, after the aiming bolt is tightened and the aiming rod is engaged with the aiming bolt, a support frame for supporting the aiming rod needs to be additionally assembled in the final step (the support frame is tightened to the lamp module using fastening bolts). As a result, in the final assembly line (the production line where the headlights are assembled to the body), there are problems with assembly performance, operability, and reduced productivity.

[0021] Furthermore, in related technologies, it is difficult to provide the aiming rod and support bracket as components integrated with the lamp module (e.g., headlight module), and the aiming rod and support bracket need to be provided and managed separately from the lamp module, which complicates the management and assembly process. Therefore, the problem is the increased time and cost required to assemble the headlights.

[0022] However, according to embodiments of this disclosure, in a first position where the aiming stalk is spaced apart from the aiming bolt, the aiming bolt is allowed to rotate fully. Furthermore, when the aiming stalk moves to a second position where it engages with the aiming bolt, the movement of the aiming stalk is restricted. Therefore, the following advantages can be achieved: simplifying the process of assembling a lamp unit, including a lamp module and a lamp aiming device, to the vehicle body, and improving assembly performance and operability.

[0023] In particular, according to embodiments of this disclosure, the aiming rod and the support frame are modularized and provided in a state of temporary assembly with the lamp module (the aiming rod and the support frame are provided in a state where the support frame is pre-secured to the lamp module before the aiming bolts are fully tightened). Therefore, the process of using fastening bolts to secure the support frame to the lamp module in the final assembly line can be eliminated.

[0024] Furthermore, the aiming lever can be fully assembled simply by performing the task of pushing the aiming lever on the final assembly line. Therefore, it is advantageous to simplify the process of assembling the lamp unit on the final assembly line and improve assembly performance and operability.

[0025] The locking part may have various structures that enable the aiming rod to be supported in a first position and locked in a second position.

[0026] For example, the locking part may include: a latching protrusion located on the outer surface of the aiming rod; a support protrusion located on the inner surface of the support frame and configured to support the latching protrusion in the first position; and a latching hole located in the support frame and configured to lock the latching protrusion in the second position.

[0027] Specifically, the latching protrusion may be configured as a continuous ring in the circumferential direction of the aiming rod.

[0028] As described above, the latching protrusion is configured as a continuous ring, so the latching protrusion can be easily supported on the support protrusion regardless of the rotation angle of the aiming rod relative to the support frame.

[0029] According to an exemplary embodiment of this disclosure, the lamp aiming device may include a connecting portion, one end of which is connected to the support frame and the other end of which is disposed in the snap-fit ​​hole. The support protrusion may be disposed at the other end of the connecting portion and spaced apart from the inner wall surface of the snap-fit ​​hole.

[0030] According to an exemplary embodiment of the present disclosure, the lamp aiming device may include a slit disposed in the support frame and adjacent to the support protrusion.

[0031] Since the slits are located on the outer periphery of the support protrusion as described above, the dynamic characteristics of the support protrusion relative to the support frame (the characteristics that allow the support protrusion to move freely) can be improved.

[0032] According to an exemplary embodiment of the present disclosure, the lamp aiming device may include an inclined guide surface disposed on the support protrusion, and the latching protrusion may enter the latching hole along the inclined guide surface.

[0033] As described above, the inclined guide surface is provided on the support protrusion, which has the advantage of minimizing the impact and noise caused by the contact between the latching protrusion and the support protrusion, and ensuring a smoother movement of the latching protrusion (the aiming rod moves from the first position to the second position) when the latching protrusion crosses the support protrusion.

[0034] Another exemplary embodiment of this disclosure provides a lamp unit, including: a lamp module; an aiming bolt connected to the lamp module and configured to adjust the light emission direction of the lamp module; an aiming rod configured to move between a first position spaced apart from the aiming bolt and a second position where the aiming rod engages with the aiming bolt; a support frame located on the lamp module for supporting the aiming rod on the lamp module; and a locking portion configured to lock the aiming rod onto the support frame when the aiming rod moves from the first position to the second position.

[0035] According to an exemplary embodiment of the present disclosure, the locking portion may include: a latching protrusion located on the outer surface of the aiming rod; a support protrusion located on the inner surface of the support frame and configured to support the latching protrusion in the first position; and a latching hole located in the support frame and configured to lock the latching protrusion in the second position.

[0036] According to an exemplary embodiment of this disclosure, the lamp unit may include a connecting portion, one end of which is connected to the support frame and the other end of which is disposed in the snap-fit ​​hole. The support protrusion may be disposed at the other end of the connecting portion and spaced apart from the inner wall surface of the snap-fit ​​hole.

[0037] According to an exemplary embodiment of the present disclosure, the lamp unit may include an inclined guide surface disposed on the support protrusion, and the snap-fit ​​protrusion may enter the snap-fit ​​hole along the inclined guide surface.

[0038] According to an exemplary embodiment of the present disclosure, the lamp unit may include a slit disposed in the support frame and adjacent to the support protrusion.

[0039] According to an exemplary embodiment of this disclosure, the support frame may be provided in a state of being pre-fastened to the lamp module before the aiming rod moves from the first position to the second position. Attached Figure Description

[0055] refer to Figures 1 to 7 According to an embodiment of the present disclosure, a lamp aiming device 100 includes: an aiming rod 110 configured to move between a first position spaced apart from the aiming bolt 30 and a second position where the aiming rod 110 engages with the aiming bolt 30; a support frame 120 located on a lamp module 20 for supporting the aiming rod 110 on the lamp module 20; and a locking part 130 configured to lock the aiming rod 110 onto the support frame 120 when the aiming rod 110 moves from the first position to the second position.

[0056] For reference, the lamp aiming device 100 according to embodiments of this disclosure can be primarily used to adjust the light emission direction of a lamp used for lighting functions (e.g., headlights or fog lights) or signaling functions (e.g., turn signals, taillights, brake lights, or side markers). This disclosure is not limited or restricted by the type and structure of the lamp (lamp module) to which the lamp aiming device 100 is applied.

[0057] In the following text, an example will be described in which the lamp aiming device 100, including the aiming rod 110, the support frame 120 and the locking part 130, together with the lamp module 20 and the aiming bolt 30, constitutes a lamp unit 10.

[0058] More specifically, the lamp unit 10 includes: a lamp module 20; an aiming bolt 30 connected to the lamp module 20 and configured to adjust the light emission direction of the lamp module 20; an aiming rod 110 configured to move between a first position spaced apart from the aiming bolt 30 and a second position where the aiming rod 110 engages with the aiming bolt 30; a support frame 120 located on the lamp module 20 for supporting the aiming rod 110 on the lamp module 20; and a locking part 130 configured to lock the aiming rod 110 onto the support frame 120 when the aiming rod 110 moves from the first position to the second position.

[0059] The lamp module 20 can have various structures capable of emitting light. This disclosure is not limited or restricted by the type and structure of the lamp module 20.

[0060] For example, the lamp module 20 may include a lampshade (not shown), a light source (not shown) disposed in the lampshade, and a reflector (not shown) configured to reflect light emitted from the light source forward.

[0061] The structure and shape of the lampshade can vary depending on the required conditions and design specifications. This disclosure is not limited or restricted by the structure and shape of the lampshade.

[0062] Light-emitting diodes (LEDs), as semiconductor light-emitting elements, can be used as light sources, or multiple LEDs configured to emit beams of the same or different colors can be used, depending on the required conditions and design specifications. According to another embodiment of this disclosure, fluorescent lamps, incandescent lamps, or halogen lamps can be used as light sources.

[0063] The reflector can have various structures capable of reflecting light emitted from the light source forward, and this disclosure is not limited or restricted by the shape and structure of the reflector.

[0064] For example, the reflector can be formed with an inner surface in the form of an elliptical or freeform surface, and has a reflective layer (reflective surface) to reflect light generated from the light source toward a position in front of the headlight. Alternatively, the reflector can have a structure with a single focal point or multiple focal points. In particular, the light source can be positioned at or near the focal point of the reflector.

[0065] For reference, in embodiments of this disclosure, the configuration of the reflector reflecting light emitted from the light source forward can refer to the reflector reflecting light in the direction from which the light is emitted from the lamp module 10. The direction represented by the forward direction can be changed depending on the mounting position and orientation of the lamp module 10. For example, the reflector can reflect light in the direction of vehicle movement.

[0066] The aiming bolt 30 adjusts the light emission direction of the lamp module 20 by adjusting the posture (position or angle) of the reflector.

[0067] The connection structure between the aiming bolt 30 and the reflector can be modified in various ways according to required conditions and design specifications. This disclosure is not limited or restricted by the connection structure between the aiming bolt 30 and the reflector.

[0068] For example, the orientation of the reflector can be changed when the reflector coupled to (or engaged with) the aiming bolt 30 rotates by the rotation of the aiming bolt 30.

[0069] The aiming bolt 30 can be tightened to the lampshade by rotation (e.g., by screw tightening). A bolt gear portion 32 (e.g., a crown gear) can be provided at one end of the aiming bolt 30 and engage with the aiming rod 110 (the rod gear portion of the aiming rod).

[0070] The aiming rod 110 can engage with the aiming bolt 30, and the aiming bolt 30 rotates as the aiming rod 110 rotates.

[0071] The aiming rod 110 may have various structures capable of engaging with the aiming bolt 30. This disclosure is not limited or restricted by the structure and shape of the aiming rod 110.

[0072] For example, the aiming rod 110 can be provided in the form of a straight rod with a predetermined length. A lever gear portion 112 that meshes with the bolt gear portion 32 can be provided at one end of the aiming rod 110.

[0073] In this case, the engagement structure (shape of the gear) and transmission ratio of the lever gear portion 112 and the bolt gear portion 32 can be varied according to the required conditions and design specifications.

[0074] The support frame 120 is connected (fastened) to the lamp module 20 and supports the aiming rod 110 on the lamp module 20, so that the aiming rod 110 is rotatable.

[0075] The support frame 120 may have various structures capable of supporting the aiming rod 110.

[0076] For example, the support frame can have an approximately hollow cylindrical shape with a receiving space. The aiming rod 110 can be engaged with the aiming bolt 30 while the aiming rod 110 passes through the support frame 120.

[0077] Specifically, the support frame 120 is pre-secured to the lamp module 20 before the aiming rod 110 moves from the first position to the second position.

[0078] In this case, the state in which the support frame 120 is fastened to the lamp module 20 can be understood as the state in which the support frame 120 is fixed to the lamp module 20 using fastening bolts (e.g., four fastening bolts), that is, the state in which the support frame 120 and the lamp module 20 are fully assembled.

[0079] The aiming rod 110 can move linearly between a first position where the aiming rod 110 is spaced apart from the aiming bolt 30 and a second position where the aiming rod 110 is engaged with the aiming bolt 30.

[0080] In this case, the state in which the aiming rod 110 is located at a first position spaced apart from the aiming bolt 30 can be understood as the state in which the aiming rod 110 is accommodated in the support frame 120 and the rod gear portion 112 is spaced apart from the bolt gear portion 32 (temporary assembly state), such as... Figure 3 and 4 As shown. Furthermore, with the aiming rod 110 in the first position, the engagement between the aiming rod 110 and the aiming bolt 30 can be released, thereby ensuring free rotation of the aiming bolt 30.

[0081] Conversely, the state in which the aiming rod 110 is in the second position where it engages with the aiming bolt 30 can be understood as the state in which the aiming rod 110 is housed in the support frame 120 and the rod gear portion 112 engages with the bolt gear portion 32 (fully assembled state), such as... Figures 5 to 7 As shown.

[0082] When the aiming rod 110 is in the first position, the locking part 130 temporarily supports the aiming rod 110 in its configuration state. When the aiming rod 110 moves from the first position to the second position, the locking part 130 locks the aiming rod 110 onto the support frame 120.

[0083] In this configuration, the aiming rod 110 being locked to the support frame 120 when it is moved to the second position can mean that the aiming rod 110 is prohibited from moving in the longitudinal direction when the rod gear portion 112 is engaged with the bolt gear portion 32 (see [link]). Figures 5 to 7 ).

[0084] The locking part 130 may have various structures that can lock the aiming rod 110 in the second position.

[0085] For example, the locking part 130 may include: a latching protrusion 132 located on the outer surface of the aiming rod 110; a support protrusion 134 located on the inner surface of the support frame 120 and configured to support the latching protrusion 132 in the first position; and a latching hole 136 located in the support frame 120 and configured to lock the latching protrusion 132 in the second position.

[0086] The latching protrusion 132 may protrude from the outer surface (e.g., the outer circumferential surface) of the aiming rod 110. This disclosure is not limited or constrained by the structure and shape of the latching protrusion 132.

[0087] Specifically, the latching protrusion 132 may be configured as a continuous ring in the circumferential direction of the aiming rod 110.

[0088] Since the latching protrusion 132 is configured as a continuous ring as described above, the latching protrusion 132 can be easily supported on the support protrusion 134 regardless of the rotation angle of the aiming rod 110 relative to the support frame 120.

[0089] According to another embodiment of this disclosure, the latching protrusion may be partially disposed at a specific position in the circumferential direction of the aiming rod. However, if the latching protrusion is partially disposed at the specific position, the latching protrusion may only be supported on the support protrusion when the aiming rod is rotated such that the latching protrusion faces (can contact) the support protrusion. Thus, the rotation angle of the aiming rod relative to the support frame can be limited.

[0090] Conversely, when the latching protrusion 132 is configured as a continuous ring, the latching protrusion 132 can be supported on the support protrusion 134 regardless of the rotation angle of the aiming rod 110 relative to the support frame 120. Therefore, the latching protrusion 132 can be configured as a continuous ring.

[0091] When the aiming rod 110 is in the first position, the support protrusion 134 supports the latch protrusion 132.

[0092] The support protrusion 134 may protrude from the inner surface (e.g., the inner circumferential surface) of the support frame 120. This disclosure is not limited or construed as to the structure and shape of the support protrusion 134.

[0093] For example, the support protrusion 134 may protrude to a height that allows the support protrusion 134 to contact the outer peripheral surface of the aiming rod 110 (e.g., a contact that allows linear movement of the aiming rod).

[0094] According to an exemplary embodiment of this disclosure, the lamp aiming device 100 may include a connecting portion 133, one end of which is connected to the support frame 120, and the other end is disposed in the snap-fit ​​hole 136. The support protrusion 134 may be disposed at the other end of the connecting portion 133 and spaced apart from the inner wall surface of the snap-fit ​​hole 136.

[0095] The connecting portion 133 can be connected to the support frame 120, while defining a cantilever beam. More specifically, one end of the connecting portion 133 (e.g., based on...) Figure 3 The upper end of the connector 133 can be fixed to the support frame 120, and the other end of the connector 133 (e.g., based on...) Figure 3The lower end of the connector 133 can be configured as a free end. The latching protrusion 132 can be elastically moved based on one end of the connector 133 (elastically moving radially on the aiming rod).

[0096] According to an exemplary embodiment of the present disclosure, the lamp aiming device 100 may include a slit 138 disposed in the support frame 120 and adjacent to the support protrusion 134.

[0097] The slit 138 can be made by partially removing (cutting) a portion of the support frame 120. This disclosure is not limited or restricted by the shape and structure of the slit 138.

[0098] For example, the slit 138 can be disposed on the left and right sides of the support protrusion 134 based on the support protrusion 134, and disposed in the upward / downward direction (based on...). Figure 3 ).

[0099] According to another embodiment of this disclosure, the slit can be provided in a left / right direction or other directions based on the support protrusion. Alternatively, the slit can have a curved shape, such as an "S" or "C" shape.

[0100] Because the slit 138, as described above, is located on the outer periphery of the support protrusion 134, the dynamic characteristics of the support protrusion 134 relative to the support frame 120 (the characteristic that allows the support protrusion 134 to move freely) can be improved. Therefore, when the aiming rod 110 moves from the first position to the second position, the latching protrusion 132 can elastically pass over the support protrusion 134 in a latching manner and then be received in the latching hole 136.

[0101] Specifically, the lamp aiming device 100 may include an inclined guide surface 134a disposed on the support protrusion 134. The latching protrusion 132 may enter the latching hole 136 along the inclined guide surface 134a.

[0102] The inclined guide surface 134a may be provided in the form of a curved or flat surface. This disclosure is not limited or restricted by the angle and structure of the inclined guide surface 134a.

[0103] Since the inclined guide surface 134a is provided on the support protrusion 134 as described above, the advantageous effect can be obtained, namely, minimizing the impact and noise caused by the contact between the latching protrusion 132 and the support protrusion 134, and ensuring a smoother movement of the latching protrusion 132 (the aiming rod 110 moves from the first position to the second position) when the latching protrusion 132 crosses the support protrusion 134.

[0104] The latching hole 136 is located in the support frame 120 to lock the latching protrusion 132 when the aiming rod 110 is moved to the second position.

[0105] The latching hole 136 may have various structures capable of locking the latching protrusion 132. This disclosure is not limited or restricted by the structure and shape of the latching hole 136.

[0106] For example, the snap-fit ​​hole 136 can penetrate the wall surface of the support frame 120 and has an approximately quadrilateral hole with a size larger than that of the support protrusion 134. The support protrusion 134 can be disposed in the approximately central portion of the snap-fit ​​hole 136 and spaced apart from the inner wall surface of the snap-fit ​​hole 136.

[0107] According to another embodiment of this disclosure, instead of snap-fit ​​holes, snap-fit ​​grooves with a recessed shape can be provided in the inner surface of the support frame.

[0108] refer to Figure 1 , Figures 3 to 4 The aiming rod 110, together with the support bracket 120, can be modularized in a temporarily assembled state with the lamp module 20 and then provided to the final assembly line (the final assembly line for assembling the lamp unit to the vehicle body). In this case, the aiming rod 110 and the support bracket 120 can be provided with the snap-fit ​​protrusion 132 supported on the support protrusion 134 without being accommodated in the snap-fit ​​hole 136.

[0109] refer to Figures 5 to 7 In the final assembly line, the aiming bolt 30 can be fully tightened by full rotation. When the uppermost end of the aiming rod 110 is pushed after the aiming bolt 30 is fully tightened, the aiming rod 110 moves from a first position to a second position. At the same time, the latching protrusion 132 is received in the latching groove (locked by the latching groove), so that the aiming rod 110 can be fully assembled.

[0110] According to the embodiments of this disclosure described above, the aiming rod 110 and the support frame 120 are modularized and provided in a state of temporary assembly with the lamp module 20 (the aiming rod 110 and the support frame 120 are provided in a state where the support frame 120 is pre-tightened to the lamp module 20 before the aiming bolt 30 is fully tightened). Therefore, the process of using fastening bolts to tighten the support frame 120 to the lamp module 20 in the final assembly line can be eliminated. This results in the following advantages: simplifying the process of assembling the lamp unit 10, including the lamp module 20 and the lamp aiming device 100, to the vehicle body, and improving assembly performance and operability.

[0111] According to the embodiments of this disclosure described above, the advantages of simplifying the lamp assembly process and improving assembly performance and operability can be obtained.

[0112] In particular, according to embodiments of this disclosure, the following advantages can be obtained: modularity and provision of aiming rods and support frames in a state of temporary assembly with the lamp module, and simplification of the assembly process in the final assembly line where the lamp is assembled to the vehicle body.

[0113] Furthermore, according to embodiments of this disclosure, the process of fastening the support frame with fastening bolts in the final assembly line can be eliminated, and the lamp can be fully assembled simply by performing the task of pushing the aiming rod.
