Description
Technical Field
[0001] The utility model relates to a lighting structure, and more specifically, to a reflective bowl and a lens module thereof, and a vehicle lamp. Background Art
[0002] Reflective bowl is a common optical equipment component, its main function is to reflect or refract light to a specific direction to achieve effective use of light. In the manufacturing process, reflective bowls are usually produced by injection molding, which can achieve efficient and large-scale production to meet the large demand of the market.
[0003] However, the injection molding process has a certain influence on the shape and performance of the reflective bowl, which may affect the optical performance of the reflective bowl. In the field of optical equipment manufacturing, the performance of the reflective bowl directly affects the performance of the optical equipment. Therefore, how to ensure the shape and performance of the reflective bowl during the injection molding process is an important research direction.
[0004] In the related art, Figure 1 As shown, since the injection port is located on the reflective bowl, the pressures on other parts of the reflective bowl and the injection port are different, which significantly affects the quality of the reflective bowl and places extremely high demands on the process of the injection molding machine.
[0005] The present application aims to provide a reflective bowl, a lens module and a car light thereof, in view of the fact that the existing reflective bowl cannot avoid the product defects caused by the injection molding process due to structural reasons. Summary of the invention
[0006] The utility model overcomes the deficiency that the existing reflective bowl cannot avoid product defects caused by the injection molding process due to structural reasons, and provides a reflective bowl and its lens module, and a car lamp, which can avoid the formation of injection molding defects on the reflective bowl, reduce process requirements, and improve yield.
[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0008] A reflective bowl comprises a reflective bowl body and a handle structure arranged on the outer edge of the reflective bowl body. The handle structure is integrally formed with the reflective bowl body, and an injection port is located at the handle structure.
[0009] The reflective bowl body of the reflective bowl carries an optical function, and the handle structure provides a function of connecting and fixing the reflective bowl with other structures and serving as a handle during the production and processing process. The handle structure is formed by injection molding like the reflective bowl body, and the two are integrally formed by the same mold, and the injection port is set on the handle structure, so that the position most likely to form defects is left on the handle structure. Since the handle structure does not participate in the reflection or refraction of the light path, it will not affect the optical performance of the reflective bowl. The handle function can also be used as a gripping handle during assembly and storage and movement. Since the sizes of reflective bowls are different, the structure of the manipulator for grabbing the reflective bowl needs to be adjusted accordingly, so that the handle structure can be grabbed to move the reflective bowl, thereby simplifying the structure of the manipulator and avoiding deformation or damage to the reflective bowl body in this process. By setting the handle structure and cooperating with the optimization of the injection molding process, defects on the reflective bowl body can be avoided, process requirements can be reduced, and the yield rate can be improved.
[0010] Preferably, the handle structure comprises a plate body, a grip body and a buckle, wherein at least part of the edges of the plate body and the reflector body are coplanar and connected. The reflector body is a quarter of an ellipsoidal surface, and specifically, the reflector body is a curved surface formed by two mutually perpendicular planes being tangent to a spherical surface. Therefore, part of the edges of the reflector are located on the same plane, and the plate body is connected to the reflector body.
[0011] Preferably, the handle body is arranged at the outer edge of the plate body, one end of the handle body is connected to the plate body, and the other end is provided with a handle suitable for grasping by a robot, the upper side of the handle is a plane and the lower side protrudes outward. Preferably, both ends of the plate body in the width direction are provided with extension ends toward the reflective bowl body, and the buckle is provided on the extension ends.
[0012] Preferably, the plate is provided with an identification code or foolproof shape for robot recognition. The foolproof shape refers to adding a small structure for identification, such as a protrusion, to the handle structure. The structure provides information about the reflective bowl through the identification code or foolproof shape, which is convenient for subsequent processing.
[0013] Preferably, the handle structure comprises a grip body, and the grip body is connected to the arc surface on the outer side of the reflective bowl body.
[0014] Preferably, the plate body has a plurality of guide rods along the length direction on both sides in the width direction, and the ends of the guide rods are designed with round heads for guiding. The structure plays a role of self-alignment, improves the assembly accuracy, and thus improves the performance of the optical device.
[0015] A lens module comprises a heat sink, a substrate, a reflective bowl as described above, an outer lens, a lens bracket, a light-shaped baffle and an LED light source, wherein the LED light source is located on the substrate and diverges light at 180 degrees, and the light is reflected by the reflective bowl body and partially blocked by the light-shaped baffle, and then incident on the reflective bowl body and refracted twice by the outer lens before being emitted to the outside. Preferably, the light-shaped baffle is connected to the reflective bowl by the buckle.
[0016] Preferably, the plate body is symmetrically provided with connecting holes, and fasteners pass through the base plate and the connecting holes to fix the reflective bowl to the base plate.
[0017] A vehicle lamp, such as the lens module described above, further comprises an outer cover.
[0018] Compared with the prior art, the beneficial effects of the utility model are:
[0019] (1) The present application provides an integrally molded handle structure on the basis of the existing reflector body, and transfers the injection molding port to the handle structure, thereby avoiding defects from being molded on the reflector body, thereby improving the optical quality of the reflector body and the yield rate;
[0020] (2) The handle structure includes a grip that facilitates the robot to grasp the reflective bowl, thereby reducing the complexity of the robot grasping the reflective bowl. For example, the handle structure is set to be double-concave, which is suitable for a double-convex robot and can be used to grasp high-precision optical components such as light baffles and external lenses.
[0021] (3) By setting up a handle structure, it is easier to assemble other parts of the structure for self-alignment, thereby improving assembly accuracy;
[0022] (4) Since the handle structure does not participate in the reflection or refraction of the light path, the identification code information can be engraved on the handle structure without significantly affecting the initial design of the light path, which facilitates subsequent processing;
[0023] (5) The handle structure may also include a grip that facilitates a robot arm to grab and remove the aluminum plating. For example, the grip is configured to be convex at the bottom and flat at the top, which facilitates the robot arm to grab and remove the aluminum plating inside the reflective bowl body.

[0038] Example:
[0039] Ginseng Figure 3 As shown, a reflector includes a reflector body 100 and a handle structure 200 arranged on the outer edge of the reflector body 100 . The handle structure 200 and the reflector body 100 are integrally formed by injection molding. The reflector is an injection molded part, and the injection port is located on the handle structure 200 .
[0040] The reflective bowl body 100 is a quarter hollow ellipsoid. Specifically, the reflective bowl body 100 is a curved surface formed by two planes tangent to a sphere. In some embodiments, the two planes are perpendicular.
[0041] The handle structure 200 includes a plate body 210, a grip body 220 and a buckle 230, wherein at least part of the edges of the plate body 210 and the reflector body 100 are coplanar and connected. The plate body 210 is a sheet-like or thin structure, and its shape is a rectangle with an arc-shaped notch, wherein the arc-shaped notch is adapted to the contour of the reflector body 100 and the plate body 210. The width of the plate body 210 should be slightly larger than the arc-shaped notch. In this embodiment, the plate body 210 coincides with any one of the aforementioned planes, and the structure can enhance the rigidity of the reflector body 100, and can also avoid stress concentration, protect the reflector body 100 during use, and avoid damage to its edges. The grip body 220 is used for grasping by a robot.
[0042] Specifically, the handle body 220 is arranged at the outer edge of the plate body 210, and the handle body 220 includes a rod body and a handle 221. One end of the rod body is connected to the plate body 210, and the other end is connected to the handle 221 suitable for the robot to grasp. The handle 221 is a flange turned out of the rod body, and the handle 221 is a thin sheet. In some preferred embodiments, the shape is rectangular. In some embodiments, the handle 221 and the rod body are of equal thickness. In other embodiments, the handle is flat on the top and convex on the bottom. In still other embodiments, the handle is concave on the top and bottom. Among them, the direction of the rod body is perpendicular to the direction of the plate body 210, and the flange is turned out in the direction away from the reflector body 100.
[0043] Ginseng Figure 7 As shown, in some embodiments, the handle structure includes a grip body, and the grip body is connected to the curved surface of the outer side of the reflector bowl body.
[0044] The plate body 210 is symmetrically provided with connection holes 250 at both ends of the handle body 220 , and the connection holes 250 are used to fix and connect other components in the lens module in the form of fasteners.
[0045] Both ends of the plate body 210 in the width direction extend toward the reflector body 100 and are provided with extension ends, and the buckle 230 is arranged on the extension ends. In some embodiments, the buckle 230 and the connecting hole 250 are respectively located at both ends of the plate body 210 in the length direction.
[0046] In some further embodiments, the plate body 210 has a plurality of guide rods 240 along the length direction on both sides of the width direction, and the ends of the guide rods 240 are designed with round heads for guiding. This structure can reduce the precision requirements of the robot and can be more easily inserted into the substrate 5.
[0047] The plate 210 is provided with an identification code or foolproof shape for identification by a code reader connected to the robot. The identification code provides the model and identification information of the reflective bowl and provides corresponding size information to facilitate subsequent assembly processing. The foolproof shape refers to adding a small structure for identification on the handle structure, such as a protrusion.
[0048] Based on the above implementation scheme, the present application also provides a lens module.
[0049] Ginseng Figure 2 , 4 , 5 and 6, a lens module includes a heat sink 6, a substrate 5, a reflective bowl, an outer lens 3, a lens bracket 4, a light-shaped baffle and an LED light source, wherein the handle structure 200 of the reflective bowl and the heat sink 6 are respectively attached to two opposite sides of the substrate 5. The connecting hole 250 on the plate body 210 passes through the substrate 5 and is fixedly connected to the substrate 5 through a fastener. The light-shaped baffle is buckled and connected to the reflective bowl through the fastener.
[0050] The other side is attached to the heat dissipation surface of the radiator 6, and the heat dissipation surface is provided with a plurality of heat dissipation fins facing away from the reflective bowl. The radiator 6 and the substrate 5 serve as a support together, and are also connected to the lens bracket 4, and the outer lens 3 is mounted on the lens bracket 4. In the open cavity formed by the reflective bowl, the outer lens 3 and the radiator 6, there is a light pattern baffle to adjust the light pattern.
[0051] The reflective bowl body 100 of the reflective bowl carries the optical function, and the handle structure 200 provides support for connecting the reflective bowl with other structures and serves as a handle during the production and processing process. The handle structure 200 is also formed by injection molding like the reflective bowl body 100, and the two are integrally formed by the same mold, and the injection port is set on the handle structure 200, so that the position most likely to form defects is left on the handle structure 200. Since the handle structure 200 does not participate in the reflection or refraction of the light path, it will not affect the optical performance of the reflective bowl. The handle function can also be used as a gripping handle during assembly and storage and movement. Since the sizes of reflective bowls are different, the structure of the manipulator for grabbing the reflective bowl needs to be adjusted accordingly, so that the handle structure 200 can be grabbed to move the reflective bowl, thereby simplifying the structure of the manipulator and avoiding deformation or damage to the reflective bowl body 100 in this process. By setting the handle structure 200 and cooperating with the optimization of the injection molding process, defects on the reflective bowl body 100 can be avoided, process requirements can be reduced, and yield can be improved.
[0052] Based on the above implementation scheme, the present application also provides a vehicle lamp, which also includes a corresponding lampshade.
[0053] The above-described embodiments are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
