Description

Technical Field

[0001] This invention relates to the field of automotive lighting technology, and more particularly to a mounting structure for lighting decorative parts. Background Technology

[0002] With the development of the automotive industry, the requirements for the design and layout space of automotive parts are becoming increasingly stringent, often resulting in insufficient space for part placement. In some existing automotive lighting fixtures, the positioning and mounting points of plastic decorative parts and other components are generally secured using numerous screws and clips. If there are insufficient mounting points, parts are prone to problems such as unstable positioning, wobbling, and poor dimensional fit. Disassembly requires individual removal, consuming significant time. If snap-fit ​​points are used, the mounting points are easily damaged during disassembly and pulling, causing damage to the parts themselves and the mounting points of other components, rendering the parts unusable. To control dimensional gaps and prevent interference from scratches and compression, limiting ribs are usually designed, but some limiting rib structures are easily exposed, affecting the appearance. Therefore, a new mounting structure for lighting fixture decorative parts is needed. Summary of the Invention

[0003] The purpose of this invention is to provide a lamp decorative component installation structure that ensures that the positioning, assembly, matching dimensions, and appearance of the decorative component on the other component meet the requirements when the decorative component itself is not strong enough and there are not enough positioning and installation points, while also facilitating disassembly and assembly.

[0004] The technical solution adopted by this invention to solve its technical problem is: A lamp decorative component mounting structure includes a lamp base, an inner frame, a lamp cover, and decorative components. The lamp base has a plurality of first limiting ribs protruding from it, and the decorative components have limiting holes at positions corresponding to the first limiting ribs. The first limiting ribs are inserted into the limiting holes. The top of the lamp cover is provided with a limiting protrusion, and one side of the limiting protrusion is provided with a number of second limiting ribs. There is an insertion gap between the second limiting ribs and the top of the lamp cover. One side of the decorative piece is provided with an insertion edge, which is inserted into the insertion gap; The decorative component is provided with several sets of third limiting ribs at parallel intervals, and the third limiting ribs overlap the top of the second limiting ribs.

[0005] Preferably, in conjunction with the above scheme, a guide trajectory surface is provided on one side of the first limiting rib, and the guide trajectory surface includes a first guide inclined surface, a second guide inclined surface, and a guide plane arranged sequentially from bottom to top.

[0006] Preferably, in conjunction with the above scheme, the protrusion on the insertion edge is provided with a number of limiting protrusions, and a slot is provided on the insertion edge corresponding to the position of the limiting protrusion. The protrusion on the inner frame is provided with a number of buckles at intervals, and the buckles engage with the slots.

[0007] Preferably, in conjunction with the above scheme, a limiting buffer strip is provided on the side of the limiting protrusion facing the limiting boss, and the limiting buffer strip is used to limit the limiting boss and buffer it during installation.

[0008] Preferably, in conjunction with the above scheme, the third limiting rib is provided with a first limiting groove, and the upper edge of the first limiting groove overlaps the upper end of the second limiting rib.

[0009] Preferably, in conjunction with the above scheme, the first limiting groove is an inverted L-shaped groove.

[0010] Preferably, in conjunction with the above scheme, the third limiting rib is fixedly connected to the bottom of the decorative piece and the top of the insertion edge.

[0011] Preferably, in conjunction with the above scheme, a second limiting groove is provided on the insertion edge below the third limiting rib, and a number of reinforcing ribs are provided at intervals on the second limiting rib, with the bottom of the reinforcing ribs overlapping in the second limiting groove.

[0012] Preferably, in conjunction with the above scheme, the lamp base is provided with several sets of screw-in protrusions, and the decorative part is provided with fixing holes at the positions corresponding to the screw-in protrusions. The fixing holes and the screw-in protrusions are detachably and fixedly connected by screws.

[0013] Preferably, in conjunction with the above scheme, a number of fixed seats are provided at fixed intervals on one side of the lamp base, and the screw-in protrusion and the first limiting rib are fixedly set on the fixed seats.

[0014] The beneficial effects of this invention are as follows: This invention provides a lamp decorative component mounting structure that solves the problem of insufficient mounting points for plastic decorative components on the mounting parts. The limiting ribs between the lamp and the plastic decorative component are not exposed, resulting in a beautiful and defect-free appearance. It also solves the dimensional control defects caused by insufficient strength of the parts themselves, such as shrinkage, torsion, and rebound.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. It should be noted that, unless otherwise specified, the implementation methods and features in the implementation methods in this disclosure can be combined, separated, interchanged, and / or rearranged. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] In the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0036] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “(the)” are also intended to include the plural forms. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0037] In some existing automotive lighting assemblies, there are components such as lamp base, lamp housing, housing frame, lamp cover and trim. To ensure the stability of the parts assembly, while ensuring the strength of the parts themselves, it is also necessary to use reasonable structural design of positioning pins, screws, clips and other structures to ensure the stability of the parts installation and the control of dimensions. In some existing lighting assemblies, the positioning and mounting points of plastic decorative parts are generally secured using screws, clips, etc. If there are insufficient mounting points, the parts are prone to problems such as unstable positioning, wobbling, and poor dimensional fit. To control the dimensional gaps between the lighting fixture and the plastic parts and to prevent interference, scratches, and compression, limiting ribs are usually designed. However, these limiting ribs are easily exposed, affecting the appearance. Some plastic parts are designed to be relatively thin and lack strength due to factors such as space, cost, and manufacturing quality. During assembly, it is necessary to control the stretching of the hardware to control the shape of the parts. Conventional parts use positioning pins or positioning clips, which are designed with reserved positioning and assembly gaps, affecting the positioning accuracy of the parts. The assembly of plastic parts often requires a large number of mounting screws and clips for fastening. During disassembly, they need to be disassembled one by one, which takes up a lot of time. If the plastic parts are designed with snap-fit ​​points, the mounting points are easily damaged during disassembly and pulling, causing damage to the parts themselves and the mounting points of the other parts, making the parts unusable. Generally, the design requirement is that the mounting points should not be damaged after three insertions and removals.

[0038] The purpose of this invention is to address situations where plastic decorative parts for lighting fixtures are limited by various factors, resulting in insufficient strength or the inability to design and arrange sufficient positioning and installation points. Through the adaptive design of the product positioning structure, this invention ensures stable positioning and assembly of the plastic decorative parts on the adjacent parts, eliminates appearance defects, facilitates easy assembly and disassembly, and provides positioning and correction. By directly associating the positioning, it ensures that the matching (gap, surface difference) dimensions with the surrounding parts meet the requirements.

[0039] The main design improvement in this invention is the use of directional and auxiliary limiting mechanisms to replace conventional mounting points in areas where parts lack standard positioning and mounting points (such as screw fastening or snap-fit ​​installation). This reasonable limiting method controls the shrinkage and deformation of parts due to insufficient strength. Furthermore, it breaks away from conventional external limiting mechanisms by incorporating them within the bottom cavity of the part, ensuring no visible shrinkage defects and guaranteeing sufficient positioning strength. This mounting and positioning structure also optimizes conventional installation and disassembly defects (such as time commitment, difficulty in disassembly, and damage to mounting points).

[0040] The lamp trim mounting structure of this invention can be applied to the marker lights on the roof rack, and can be installed on the front and rear sides of the roof rack. In this embodiment, the lamp trim mounting structure is located on the rear side of the roof rack. The roof rack marker light is a warning light device mainly used to indicate the presence, width, and height of a vehicle, improving driving safety in low-visibility environments such as nighttime, dusk, rain, and fog. It emits soft yet clear light, outlining the vehicle's contours without causing glare to other drivers. In low light or inclement weather, the marker lights help other vehicles quickly identify your position and overall size, effectively reducing the risk of scratches, rear-end collisions, and other accidents. This function is particularly important for large vehicles or models whose bodies are widened after adding a roof rack. Whether driving long distances, in mountainous areas, or temporarily parking, turning on the marker lights makes the vehicle more visible in the environment, essentially outlining a "safety contour" around the vehicle, enhancing practicality and style.

[0041] like Figures 1 to 8 The illustrated lamp decorative component installation structure includes a lamp base 1, an inner frame 2, an inner lamp assembly 3, a lamp cover 4, and a decorative component 5. The inner lamp assembly 3 is screwed to the lamp base 1, and the inner frame 2 is also screwed to the lamp base 1. The lamp cover 4 is fitted onto the inner frame 2. The plastic decorative component 5 is installed above the lamp base 1 and the lamp cover 4. While the mounting and positioning design on the lamp base 1 is easy to implement, the lamp cover 4 is difficult to position for screws or clips on the decorative component 5 due to space constraints, assembly direction, and mold design. This results in the lack of positioning points in the Z and X directions of the mating area between the plastic decorative component 5 and the lamp cover 4 after assembly, leading to instability and affecting the surface difference between the decorative component 5 and the lamp cover 4, and potentially causing abnormal noise.

[0042] like Figures 5 to 8 As shown, the lamp base 1 has several sets of first limiting ribs 13 protruding upwards, and the decorative part 5 has limiting holes 52 at the positions corresponding to the first limiting ribs 13. The first limiting ribs 13 are used to be inserted into the limiting holes 52 during assembly. In this embodiment, the first limiting ribs 13 and the limiting holes 52 play the role of X-axis assembly limiting.

[0043] like Figure 6 , Figure 11 , Figure 13 and Figure 14 As shown, the top of the lamp cover 4 has an upwardly protruding limiting edge 41, and the rear side of the limiting edge 41 has several sets of second limiting ribs 42, such as... Figure 7 and Figure 13As shown, an insertion gap 44 is provided between the second limiting rib 42 and the top of the lamp cover 4; in this embodiment, the limiting protrusion 41 is vertically arranged on the top of the lamp cover 4.

[0044] like Figure 5 As shown, the decorative part 5 has a plug-in edge 53 on its rear side, which extends forward and inserts into the plug-in gap 44; in this embodiment, the limiting protrusion 41 cooperates with the plug-in edge 53 to play the role of X-direction assembly limiting.

[0045] like Figure 5 , Figure 9 , Figure 12 and Figure 14 As shown, the decorative component 5 is provided with several sets of third limiting ribs 54 arranged parallel to each other, and the third limiting ribs 54 overlap the top of the second limiting ribs 42. In this embodiment, the third limiting ribs 54 cooperate with the second limiting ribs 42 to play the role of limiting assembly in the Z direction.

[0046] To facilitate the assembly of decorative piece 5 onto lamp base 1, such as Figure 6 As shown, a guide track surface 14 is provided on the rear side of the first limiting rib 13.

[0047] like Figure 10 As shown, the guide trajectory surface 14 includes a first guide slope 141, a second guide slope 142, and a guide plane 143 arranged sequentially from bottom to top. The connection between the first guide slope 141 and the second guide slope 142, and the connection between the second guide slope 142 and the guide plane 143, are all provided with R-angle transitions. When the decorative part 5 is assembled from back to front, the front end of the decorative part 5 will first contact the first guide slope 141 and move diagonally upward along the first inclined trajectory. Then, the front end of the decorative part 5 will contact the second guide slope 142 and continue to move diagonally upward along the second inclined trajectory until the bottom front side of the decorative part 5 crosses the second guide slope 142 and contacts the guide plane 143. At this time, the decorative part 5 is pushed forward and slides forward on the guide plane 143 until the first limiting rib 13 is aligned with the limiting hole 52. Then, the decorative part 5 is moved downward and the first limiting rib 13 is inserted into the limiting hole 52 to complete the X-axis assembly limiting and also prevent the decorative part 5 from translating in the Y-axis.

[0048] To better match the size of the limiting hole 52, a limiting slope 144 is also provided on one side of the first limiting rib 13. When the decorative part 5 moves downward for assembly, the first limiting rib 13 gradually enters the limiting hole 52. Due to the presence of the limiting slope 144, the first limiting rib 13 will be in close contact with the inner wall of the limiting hole 52 at a certain height, thus preventing the first limiting rib 13 from wobbling in the limiting hole 52.

[0049] To facilitate the assembly of the decorative piece 5 with the inner frame 2 of the lamp, such as Figure 7 and Figure 12 As shown, the insert edge 53 has a forward-protruding section with several sets of limiting bosses 531 spaced apart. A slot 532 is provided on the insert edge 53 corresponding to the position of the limiting bosses 531. The inner frame 2 has a rearward-protruding section with several sets of latches 21 spaced apart. The latches 21 engage with the slots 532. After the decorative piece 5 is pushed forward to its limit position, the limiting bosses 531 will first contact the limiting buffer strip 6, and then the lower end of the latches 31 will engage with the slots 532, completing the X-axis limiting assembly.

[0050] To prevent damage to the parts during the assembly of decorative part 5, it is necessary to improve the positioning stability of the plastic decorative part 5 on the lamp fixture, avoid shaking, and prevent abnormal noise. Figure 6 As shown, a limiting buffer strip 6 is provided on the side of the limiting protrusion 41 facing the limiting boss 531. In this embodiment, the limiting buffer strip 6 can be made of adhesive strip, felt, foam, etc. The limiting buffer strip 6 is connected to the rear side of the limiting protrusion 41 and is used to limit the limiting boss 531 and buffer it during installation. When the decorative part 5 is moved forward for assembly, the insertion edge 53 will be inserted into the insertion gap 44. During the assembly process, the limiting boss 531 may collide with the limiting protrusion 41, causing damage to the plastic parts. The limiting buffer strip 6 is attached to the rear side of the limiting protrusion 41, which not only limits the limiting boss 531 well, but also provides a good buffering effect, and better secures the decorative part 5.

[0051] In order to better limit the assembly of the decorative part 5 in the Z direction, the third limiting rib 54 is provided with a first limiting groove 541, and the upper edge of the first limiting groove 541 overlaps the top of the second limiting rib 42.

[0052] Conventional plastic retaining structures are designed at the boundary of the decorative part 5 or on the interlocking edge 53. This design takes into account the high requirements for controlling the gap between the lamp and the plastic decorative part 5. If a retaining structure is conventionally designed between the lamp and the decorative part 5, the upper limit of the retaining structure would be visible (due to the transparency of the lampshade, the upper limit would appear as a localized protrusion, which would be inconsistent with the surrounding area and extremely abrupt). This design of the retaining structure for the plastic decorative part 5 incorporates material at the inner bottom of the decorative part 5 to avoid the problem of external leakage. Considering that the plastic decorative part 5 is an exterior part, adding a third retaining rib 54 inside the exterior part could lead to shrinkage during the molding process. A thickness of 0.8mm for the third retaining rib 54 would not affect the appearance of the part, but considering that 0.8mm might not be strong enough to guarantee the positioning control requirements of the part, in this embodiment, the third retaining rib 54 is arranged in pairs of parallel intervals, with several pairs spaced along the length of the decorative part 5, to ensure more stable overlapping and retaining. The structure of the third limiting rib 54 and the first limiting groove 541 can restrict the upper position of the second limiting rib 42.

[0053] In order to better coordinate the lap joint of the third limiting reinforcement 54 and the second limiting reinforcement 42 for limiting, such as Figure 12 As shown, the first limiting groove 541 is an inverted L-shaped groove. In this embodiment, the first limiting groove 541 can be set as a right-angle groove. The first limiting groove 541 is opened at the lower part of the third limiting rib 54, forming a notch structure for overlapping with the upper end face of the second limiting rib 42.

[0054] To increase the structural strength of the third limiting rib 54, the third limiting rib 54 is fixedly connected to the bottom of the decorative part 5 and the top of the insertion edge 53. The third limiting rib 54 extends from the bottom of the decorative part 5 to the insertion edge 53, forming a triangular structure, which strengthens the decorative part 5 as a whole and prevents deformation and breakage of the insertion edge 53.

[0055] In order to better perform Z-direction limit assembly on the decorative part 5, a second limit groove 55 is provided at a position on the insertion edge 53 below the third limit rib 54. A number of groups of reinforcing ribs 43 are arranged at intervals on the second limit rib 42, and the bottom of the reinforcing rib 43 is lapped in the second limit groove 55. In this embodiment, three groups of reinforcing ribs 43 are vertically and fixedly connected to each group of second limit ribs 42. The three groups of reinforcing ribs 43 are arranged in parallel. Two of the three groups of reinforcing ribs 43 are located at the left and right ends of the second limit rib 42, and the other group of reinforcing ribs 43 is located in the middle of the second limit rib 42. The three groups of reinforcing ribs 43 and a group of second limit ribs 42 are fixedly connected to form a king-shaped structure, which can not only play a good role in structurally strengthening the second limit rib 42, but also the lower end of the reinforcing rib 4 is lapped on the bottom surface of the second limit groove 55. Through the matching structure of the reinforcing rib 4 and the second limit groove 55, the lower end position of the second limit rib 42 can be restricted. The rear part of the reinforcing rib 43 is a trapezoidal structure, which plays a role in guiding and limiting.

[0056] In this embodiment, through the matching limit structure of the third limit rib 54 and the first limit groove 541, and through the matching limit structure of the reinforcing rib 43 and the second limit groove 55, the Z-direction degrees of freedom in the upper and lower directions of the decorative part 5 can be simultaneously restricted, avoiding situations such as looseness and shaking of the decorative part 5, and ensuring more stable connection.

[0057] In order to better adapt to the processing and assembly errors of parts, in this embodiment, the width of the second limit groove 55 can be set to be greater than the length of the second limit rib 42 to better adjust and adapt the assembly. If the width of the second limit groove 55 is set to be slightly greater than or the same as the length of the second limit rib 42, it is not conducive to assembly.

[0058] In order to facilitate fixing the decorative part 5 on the lamp base 1, a number of groups of screw-connected convex columns 12 are convexly provided on the lamp base 1. A threaded hole is provided in the screw-connected convex column 12. A fixing hole 51 is provided at a position on the decorative part 5 corresponding to the screw-connected convex column 12. The fixing hole 51 and the screw-connected convex column 12 are detachably fixedly connected by screwing.

[0059] In order to facilitate the assembly of parts and limit the Z-direction translation of the plastic decorative part 5, a number of groups of fixing seats 11 are convexly and fixedly arranged at intervals on the front side of the lamp base 1. The screw-connected convex columns 12 and the first limit ribs 13 are fixedly arranged on the fixing seats 11. The fixing seats 11 are used to be fixedly connected to the luggage rack by screwing. Since the fixing seats 11 are arranged on the front side of the lamp base 1, the arrangement of the screw-connected convex columns 12 and the first limit ribs 13 on the fixing seats 11 can facilitate the assembly and limit of the decorative part 5. At the same time, the screw-connected convex columns 12 and the first limit ribs 13 can be connected by a reinforcing rib to play a role in structural strengthening and prevent the screw-connected convex columns 12 and the first limit ribs 13 from being deformed and broken during the assembly process.

[0060] like Figure 17 As shown, the plastic decorative part 5 is designed to be relatively thin due to factors such as cost, layout space, and mold structure design. The structural deficiencies in its design make it prone to shrinkage and deformation. If a conventional approach is used, with a locating pin at one end to control the X-axis, the other end is susceptible to shrinkage and deformation, affecting the clearance between the part and the lamp or the dimensional control requirements for assembly. This plastic decorative part 5 corrects the dimensional problems caused by shrinkage by separating the control limits at the front and rear ends. This not only corrects the part's dimensions but also eliminates conventional locating and assembly gaps, improving the dimensional accuracy after assembly.

[0061] The assembly method of the lamp decorative parts in this embodiment: Step 1: First, bring the decorative piece 5 close to the top of the lamp cover 4, align the insertion edge 53 on the back of the decorative piece 5 with the insertion gap 44 between the second limiting rib 42 and the top of the lamp cover 4, and roughly align the limiting protrusion 531 on the insertion edge 53 with the buckle 21 on the inner frame 2. Step 2: Move the decorative piece 5 forward and insert the insertion edge 53 into the insertion gap 44. At this time, the second limiting rib 42 and the reinforcing rib 43 are also aligned with the second limiting groove 55. Step 3: Continue to move the decorative piece 5 forward and raise the front of the decorative piece 5 appropriately (since the decorative piece 5 is a plastic part, it can deform to a certain extent when this operation is performed). The front end of the decorative piece 5 first contacts the guide track surface 14 and moves diagonally upward along the guide track surface 14. Step 4: Continue to move the decorative piece 5 forward until the bottom front side of the decorative piece 5 contacts the guide plane 143, and push the decorative piece 5 forward to slide it forward on the guide plane 143 until the first limiting rib 13 is aligned with the limiting hole 52. Step 5: Move the front part of the decorative part 5 downward (or use the elasticity of the plastic decorative part 5 to make the front part of the decorative part 5 move downward automatically) so that the first limiting rib 13 is inserted into the limiting hole 52. At this time, the fixing hole 51 on the decorative part 5 is also aligned with the screw protrusion 12 on the lamp base 1; at the same time, the upper groove edge of the first limiting groove 541 overlaps the top of the second limiting rib 42, and the bottom of the reinforcing rib 43 also overlaps in the second limiting groove 55. Step 6: Press down the decorative piece 5 so that the buckle 21 on the inner frame 2 snaps into the slot 532 on the insertion edge 53; Step 7: Use bolts to screw into the fixing holes 51 and the threaded protrusions 12 to fix the decorative part 5 onto the lamp, thus completing the installation and fixing of the decorative part 5.

[0062] The method for disassembling the lamp decorative parts in this embodiment is as follows: Step 1: First, unscrew the bolts in the fixing hole 51 and the threaded protrusion 12; Step 2: Lift the front part of the decorative piece 5 upwards so that the first limiting rib 13 disengages from the limiting hole 52; Step 3: During the process of lifting the decorative piece 5 upwards, the buckle 21 on the inner frame 2 also disengages from the slot 532 on the insertion edge 53; Step 4: Continue moving decorative piece 5 backward to remove it from the lamp.

[0063] This invention, through its novel design, offers the following advantages: 1. It solves the problem of insufficient installation points for plastic decorative parts on hand parts; 2. The limiting ribs between the lamps and the plastic decorative parts are not exposed, and the appearance is beautiful and without defects; 3. Solve dimensional control defects caused by insufficient strength of the parts themselves (such as shrinkage, twisting, and rebound); 4. By using multiple sets of positioning and limiting structures, conventional positioning and assembly gaps are eliminated, improving the dimensional accuracy of parts after assembly; 5. It facilitates the assembly and disassembly of parts and avoids damage to the mounting points during disassembly.
