Description

Technical Field

[0001] This utility model relates to the field of automotive grille technology, and in particular to an automotive grille with a seamless coating. Background Technology

[0002] A car grille is an air intake cover structure installed at the front of a car. It is mainly made of plastic, metal, or composite materials and has multiple functions, including ventilation and heat dissipation, protection of the engine compartment, and aesthetic enhancement of the vehicle's appearance. It is typically designed with a regularly arranged perforated structure to guide airflow into the engine compartment, enhancing the heat dissipation efficiency of the engine and cooling system, while also effectively preventing the intrusion of foreign objects.

[0003] Traditional automotive grilles typically consist of a complex structure composed of an outer frame and several internal partitions. During the painting process, their multi-angled, three-dimensional structure easily creates blind spots, leading to uneven accumulation of spray atomized particles on the grille surface. This is particularly true at the junction of the frame and partitions, where paint tends to accumulate, causing paint retention or backflow. This results in inconsistent coating thickness, uneven surface texture, and noticeable paint marks and runs. This not only severely affects the aesthetic consistency of the vehicle's front end but also easily leads to coating peeling due to insufficient surface adhesion, resulting in a series of quality control problems such as poor product appearance, increased rework rates, and decreased production yield. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a car grille with seamless coating, comprising a frame plate and a grille assembly, wherein the grille assembly is detachably installed inside the frame plate; during spraying, the grille assembly and the frame plate are sprayed separately to achieve seamless coating; wherein, the frame plate is provided with a groove for installing the grille assembly, and the groove guides the sprayed paint during the spraying of the frame plate, thereby achieving further seamless coating of the outer surface of the frame plate.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Implementation examples, based on Figures 1-8 As shown in the figure, the present invention provides a car grille with traceless coating, including a frame plate 1 and a grille assembly 2, wherein the grille assembly 2 is detachably installed inside the frame plate 1; during spraying, the grille assembly 2 and the frame plate 1 are sprayed separately to achieve traceless coating; wherein, the frame plate 1 is provided with a groove 5 for installing the grille assembly 2, and the groove 5 guides the sprayed paint during the spraying of the frame plate 1, thereby achieving further traceless coating of the outer surface of the frame plate 1.

[0021] The aforementioned seamless coating for automotive grilles optimizes the traditional one-piece structure into a split structure consisting of a frame plate 1 and a detachable grille assembly 2. Firstly, the modular assembly of the grid assembly is achieved in the structural design. The frame plate 1 is provided with a sliding groove 5 for installing the grid plate assembly 2. The grid plate assembly 2 can be disassembled and separated from the frame plate 1 before spraying, thereby realizing the independent treatment of the two parts of the structure in the spraying process. During spraying, frame plate 1 and grid plate group 2 are coated in a undisturbed state, avoiding problems such as obstruction, paint accumulation and spraying dead corners caused by structural intersection, which significantly improves the uniformity and adhesion of surface spraying. In addition, the groove 5 of the frame plate 1 also has a guiding function during the spraying process, which can guide excess paint to shrink and deposit in the direction of the groove 5, avoiding the formation of irregular paint marks on the outer surface of the frame plate 1, achieving a high-quality coating effect without flaws in appearance, and fundamentally solving the problem of poor spraying caused by the complex structure of traditional grilles.

[0022] In this embodiment, the grid plate group 2 includes a first vertical plate 201, and each grid plate group 2 is composed of two first vertical plates 201. The first vertical plate 201 has a through groove 204 inside to reduce mass. The upper and lower parts of the frame plate 1 are slidably contacted with two of the sliding grooves 5 opened on the inner wall of the frame plate 1 to achieve guiding and lateral limiting actions. Each sliding groove 5 of each frame plate 1 has two limiting holes 6, and two first screws 203 are screwed into the screw holes 202 opened on the upper and lower parts of each first vertical plate 201, and the main body of the first screw 203 is located in the limiting hole 6 to achieve secondary limiting action. In use, the first vertical plate 201 is guided and installed through the sliding groove 5, and then the first screw 203 is screwed into the first vertical plate 201 through the limiting hole 6.

[0023] By using the separate structural design of the grid plate group 2 and the frame plate 1, the surface quality and work efficiency during the spraying process are effectively improved. The grid plate group 2 consists of two first vertical plates 201, and each first vertical plate 201 has a through groove 204 structure inside. The through groove 204 can reduce the overall weight and save raw materials. In the actual assembly process, the inner side of the frame plate 1 is provided with several sliding grooves 5. The first vertical plate 201 of the grid plate group 2 is guided up and down through the sliding grooves 5 to achieve precise installation. The sliding grooves 5 also serve the dual functions of guiding and lateral limiting to ensure stable and reliable installation. To further enhance the structural strength and resistance to displacement, each slide 5 has a limiting hole 6 at both the upper and lower ends of its inner wall, corresponding to the upper and lower screw holes 202 of the first vertical plate 201. During operation, the two first screws 203 are passed through the limiting holes 6 in the slide 5 and screwed into the screw holes 202 on the vertical plate, so that the main body of the first screw 203 is firmly embedded in the limiting hole 6. This achieves additional secondary limiting control on the basis of the limiting of the slide 5, avoiding loosening, displacement or misalignment caused by vibration or handling. Through the above structural combination, not only is efficient assembly and disassembly, reuse and precise positioning of components achieved, but also the surface of each component is unobstructed, the edges are neat and the stress is uniform during the spraying process. This avoids the defects such as spraying material accumulation, obstruction and dripping caused by complex junctions in traditional grid structures, significantly improving the consistency and aesthetics of the finished sprayed product, thereby achieving a high-quality and traceless coating effect.

[0024] In this embodiment, the edge of the frame plate 1 is tapered, and a side grid plate 3 is fixedly installed at the tapered position of the frame plate 1. The side grid plate 3 is solid and is used to support the tapered shape of the frame plate 1. The side grid plate 3 includes a second vertical plate 301. The second vertical plate 301 is slidably installed in the groove 5 at the tapered position of the frame plate 1 and is fixedly installed by the second screw 303. An inclined plate 302 for penetrating into the tapered cavity of the frame plate 1 is fixedly connected to one side of the second vertical plate 301. The top of the inclined plate 302 is slidably connected to the frame plate 1.

[0025] To further enhance the stability and coating integrity of the grid structure, the edge of the frame plate 1 adopts a tapered structure design. This tapered edge not only facilitates the natural flow and transition of paint during the spraying process and avoids paint piling at the edge, but also enhances the overall resistance to deformation through structural reinforcement. A solid side grid plate 3 is fixedly installed on the conical structure. The side grid plate 3 includes a second vertical plate 301, which is mainly used to provide physical support for the conical structure and prevent the edge of the frame plate 1 from deforming due to force during processing or use. The second vertical plate 301 is slidably installed in the pre-set groove 5 at the conical position and is securely connected by the second screw 303 passing through the limiting structure, ensuring a strong and integrated connection between it and the frame plate 1. In addition, a sloping plate 302 is fixedly connected to one side of the second vertical plate 301. The sloping plate 302 can penetrate into the conical cavity of the frame plate 1, and its top is slidably connected to the frame plate 1. During installation, it can achieve self-adaptive positioning and buffer support, further enhancing the overall assembly strength and positioning accuracy. At the same time, it avoids the impact of vibration or slight misalignment on the appearance of the finished product during the spraying process, ensuring uniform spraying and a traceless coating effect on the conical edge.

[0026] In this embodiment, a mounting assembly 4 is provided at the rear of the frame plate 1 for mounting the frame plate 1 at the front air intake position of the vehicle. The mounting assembly 4 has a support frame 401, and the support frame 401 has mounting holes 404 at its four corners for connecting and mounting to the front of the vehicle. Pneumatic limiting members 405 are also fixedly mounted at the four corners of the support frame 401. The limiting members 405 are inserted into the slots 7 opened on the outside of the frame plate 1. The limiting members 405 include a transmission plate 4051 fixed on the upper part of the support frame 401. The input port 4052 of the transmission plate 4051 is in communication with the air passage opened inside the support frame 401. The transmission plate 4051 is connected by a spring inside. A sliding limit plate 4053 is installed. In its initial state, the limit plate 4053 is retracted in the transmission plate 4051 under the constraint of a spring. At this time, the transmission plate 4051 is inserted into the slot 7, and then air is injected through the valve core 402 opened in the middle of the support frame 401, thereby driving the limit plate 4053 to perform an extension and retraction action and fit into the slot 7 to achieve the limiting action. The valve core 402 is connected to the air passage opened inside the support frame 401, and a cap 403 is screwed to the valve core 402 position of the support frame 401. The transmission plate 4051 has a chamfer 4054 for guiding the transmission plate 4051 into the slot 7.

[0027] The installation structure has been further optimized. The rear of the frame plate 1 is provided with an installation component 4. The installation component 4 includes a support frame 401. The four corners of the support frame 401 are provided with installation holes 404 for docking and fixing with the preset installation position at the front of the car, so as to ensure the precise installation and firm connection of the grille on the front of the vehicle. To improve the convenience and reliability of the installation process, pneumatic limiting components 405 are also installed at the four corners of the support frame 401. The limiting components 405 are inserted into the pre-set slots 7 on the outside of the frame plate 1 to achieve precise positioning and quick fixation. Specifically, each limiting member 405 is composed of a transmission plate 4051 installed on the upper part of the support frame 401. The input port 4052 of the transmission plate 4051 is connected to the air passage provided inside the support frame 401. A limiting plate 4053 is slidably installed inside the support frame 401 by a spring. In the initial state, the limiting plate 4053 is retracted inside the transmission plate 4051 by the spring force. During installation, the operator inserts the transmission board 4051 into the slot 7. The insertion process is guided by the chamfer 4054 at the front end of the transmission board 4051 to achieve smooth docking and avoid jamming. After insertion, the air is added through the valve core 402 located in the middle of the support frame 401. The injected airflow enters the transmission plate 4051 along the air path, pushing the limiting plate 4053 to extend outward under the action of air pressure, overcoming the spring force. Finally, it fits into the slot 7 inside the slot 7 of the frame plate 1, forming a firm structural lock and realizing an efficient and reliable limiting and fixing action. To ensure airtightness and structural integrity, a cap 403 is installed on the valve core 402 by screwing, which can seal the air passage when no air is added, preventing dust and impurities from entering the system. This structure not only enables efficient positioning and quick assembly / disassembly of the grille assembly during vehicle installation, but also effectively prevents misalignment or loosening through pneumatic control of the limiting action, significantly improving installation accuracy, safety and durability. It provides stable support for the grille under high-intensity use conditions, ensuring the overall appearance and function are coordinated and unified.

[0028] The working principle of this utility model is as follows: The structural design achieves modular assembly of the grille components. The frame plate 1 has a groove 5 inside for installing the grille assembly 2. The grille assembly 2 can be disassembled from the frame plate 1 before spraying, thus enabling independent processing of the two parts during the spraying process. During spraying, the frame plate 1 and the grille assembly 2 are coated independently without interference, avoiding problems such as masking, paint accumulation, and spraying dead angles caused by structural overlap, significantly improving the uniformity and adhesion of the surface coating. Furthermore, the groove 5 of the frame plate 1 also has a guiding function during spraying, directing excess paint towards the groove 5 to shrink and deposit, preventing irregular paint marks on the outer surface of the frame plate 1, achieving a high-quality coating effect without defects, and fundamentally solving the problem of poor spraying caused by the complex structure of traditional grilles.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
