Description

Technical Field

[0001] This utility model relates to the field of automotive body component technology, specifically to a front upper component assembly. Background Technology

[0002] The front upper component assembly is a core part of the vehicle's front-end architecture, responsible for bearing the weight of front-end accessories (such as headlights and sensors), transmitting wind resistance and vibration loads during driving, and the impact force during collisions. However, existing front upper component assemblies have shortcomings: First, they have poor strength adaptability, with unreasonable application of high-strength alloys and structural design, making them prone to deformation and cracking under complex conditions (high-speed driving, collisions), threatening the safety of the front end; second, they have low accessory adaptability, with few and inaccurate installation interfaces, making accessory assembly difficult and prone to loosening, affecting functionality and lifespan; third, they have weak vehicle versatility, requiring redesign for new vehicle development, increasing R&D cycle and costs, and making it difficult to meet the needs of vehicle platform-based production. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a front upper component assembly. By optimizing the main frame structure, accessory installation component design, and adaptation structure, it solves the problems of insufficient strength, poor accessory compatibility, and low vehicle versatility, thereby improving the safety of the vehicle front, assembly efficiency, and production economy.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a front upper component assembly, including a main frame and an accessory mounting assembly.

[0005] The main frame consists of an alloy frame, which is a long strip structure adapted to the front of the vehicle. The alloy frame is made of high-strength alloy material and is integrally formed by die casting, possessing high rigidity and deformation resistance. It is equipped with a first side mounting hole, a second side mounting hole, a third side mounting hole, and a fourth side mounting hole as standardized through holes, which are adapted to the bolt connection of the longitudinal beams, cross beams, and other structures of the front of the vehicle body, so as to achieve a stable assembly of the assembly and the vehicle body. The first and second connecting holes are used to connect other auxiliary structures of the front of the vehicle, such as decorative part brackets. The reinforcing ribs are integrally formed with the alloy frame and are distributed in key stress areas, such as the middle and around the holes, to strengthen the main frame and distribute the load on the front of the vehicle, such as driving wind resistance and collision force, providing core support for the front of the vehicle body.

[0006] The accessory mounting components include an accessory mounting bracket, which is fixed to the corresponding mounting position on the main frame by welding or bolting. The first and second through slots on the accessory mounting bracket reduce weight and adapt to the accessory installation space while ensuring structural strength, such as reserving channels for vehicle light wiring harnesses. The accessory mounting holes are standardized holes that accurately match the installation interfaces of vehicle headlights, radars, and other front-end accessories. Bolts ensure that the accessories are installed securely. In conjunction with locating pins, they are used during assembly to ensure installation accuracy and prevent accessories from vibrating and loosening.

[0007] As a further improvement of this utility model, the alloy frame of the main frame can adjust its size and mounting hole layout according to the size and structural requirements of different car models. By replacing the alloy frame or using adapters, it can be adapted to the front of multiple car models from A0 to B class, achieving platform universality, shortening the development cycle of new models, and reducing mold and design costs by 30%-50% compared to traditional designs.

[0008] As a further improvement of this utility model: before assembling the accessory mounting bracket of the accessory mounting assembly, the positioning pin is used to cooperate with the pre-positioning hole of the main frame to control the error between the accessory mounting hole and the vehicle head accessory interface within ±0.5mm, thereby improving assembly efficiency and shortening the assembly time by 20%. At the same time, the shape and size of the first through groove and the second through groove can be flexibly adjusted according to the accessory shape to adapt to diverse accessory installation needs.

[0009] As a further improvement of this utility model: the central mounting hole on the main frame is located in the central area of ​​the main frame. It is a standardized through hole, and the number and diameter of the hole are set as needed. During assembly, it is used with 10.9 grade high-strength bolts and anti-loosening washers, such as spring washers, to strengthen the connection between the main frame and the front crossbeam, optimize the load transmission path of the front of the vehicle, and disperse the collision force through the central mounting hole → front crossbeam → longitudinal beam of the vehicle body, thereby improving the safety of the vehicle collision and reducing the amount of front collision deformation by 15%-25%.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the strength and deformation resistance of the front upper component assembly are greatly improved by the high-strength alloy die-casting integrated molding process of the main frame and the integrated design of the reinforcing ribs. Under conditions such as high-speed driving and collision, it can effectively resist deformation and cracking, ensure the integrity of the front structure and the function of accessories, and improve the driving and collision safety of the vehicle. According to the test, the collision resistance strength of the assembly is improved by more than 40%.

[0011] 2. In this utility model, by using the standardized holes and positioning pins of the accessory installation components, the assembly is assisted by flexible design of the through grooves, which enables precise and efficient assembly of the front accessories, avoids loosening and displacement of accessories, extends the service life of accessories, and reduces the probability of accessory failure by 35%. At the same time, the multi-model adaptability of the main frame meets the needs of automotive platform production, reduces investment in the research and development of new models, and improves the production economy of car companies.

[0017] Please see Figures 1-5 In this embodiment of the utility model, a front upper component assembly includes a main frame 1 and an accessory mounting component 2.

[0018] The main frame 1 includes an alloy frame 11, which is a long strip structure adapted to the front of the vehicle. The alloy frame 11 is made of high-strength alloy material and is integrally formed by die casting, possessing high rigidity and deformation resistance. It is provided with a first side mounting hole 12, a second side mounting hole 13, a third side mounting hole 14, and a fourth side mounting hole 15 as standardized through holes, which are adapted to the bolt connection of the longitudinal beams, cross beams, and other structures of the front of the vehicle body, so as to achieve a stable assembly of the assembly and the vehicle body. The first connecting hole 16 and the second connecting hole 18 are used to connect other auxiliary structures of the front of the vehicle, such as decorative part brackets. The reinforcing ribs 17 are integrally formed with the alloy frame 11 and are distributed in key stress areas, such as the middle and around the holes, to strengthen the main frame 1, distribute the load on the front of the vehicle, such as driving wind resistance and collision force, and provide core support for the front of the vehicle body.

[0019] The accessory mounting component 2 includes an accessory mounting bracket 21, which is assembled at the corresponding position of the main frame 1 and connected by welding or bolts. The first through slot 22 and the second through slot 24 on the accessory mounting bracket 21 reduce weight and adapt to the accessory installation space while ensuring structural strength. For example, it can reserve a channel for the vehicle headlight wiring harness. The accessory mounting hole 23 is a standardized hole position that accurately matches the installation interface of the vehicle headlights, radar and other front accessories. The bolt connection ensures that the accessory is installed firmly. It is used in conjunction with the positioning pin during assembly to ensure installation accuracy and prevent the accessory from vibrating and loosening.

[0020] The alloy frame 11 of the main frame 1 can adjust its size and mounting hole layout according to the size and structural requirements of different car models. By replacing the alloy frame 11 or using adapters, it can be adapted to the front of multiple car models from A0 to B class, achieving platform universality, shortening the development cycle of new models. Compared with traditional design, the cycle is shortened by 30%-50%, reducing mold and design costs.

[0021] Before assembling the accessory mounting bracket 21 of the accessory mounting component 2, the positioning pin is used to cooperate with the pre-positioning hole of the main frame 1 to control the error between the accessory mounting hole 23 and the vehicle head accessory interface within ±0.5mm, thereby improving assembly efficiency and shortening the assembly time by 20%. At the same time, the shape and size of the first through slot 22 and the second through slot 24 can be flexibly adjusted according to the accessory shape to adapt to diverse accessory installation needs.

[0022] The central mounting hole 3 on the main frame 1 is a standardized through hole. The number and diameter of the hole can be set as needed. During assembly, it is used with 10.9 grade high-strength bolts and anti-loosening washers, such as spring washers, to strengthen the connection between the main frame 1 and the front crossbeam, optimize the load transmission path of the front of the vehicle, and disperse the collision force through the central mounting hole 3 → front crossbeam → longitudinal beam of the vehicle body, thereby improving the safety of the vehicle collision and reducing the amount of front collision deformation by 15%-25%.

[0023] The working principle of this utility model is as follows: When the car is in motion, the main frame 1 serves as the core load-bearing structure of the front of the vehicle. Wind resistance, such as frontal wind pressure and lateral wind disturbance, acts on the front-end accessories and is transmitted to the main frame 1 via the accessory mounting components 2. The main frame 1 distributes the load through the reinforcing ribs 17 and transmits the force to the longitudinal and transverse beams of the vehicle body through the mounting holes, such as the first side mounting holes 12, thus achieving orderly distribution of the load on the front of the vehicle and avoiding localized stress concentration. In the event of a collision, such as a low-speed rear-end collision or a frontal collision, the collision force acts on the main frame 1. The high-strength material of the alloy frame 11 and... The structural reinforcement of stiffener 17 enables the main frame 1 to absorb and disperse collision energy. Through the central mounting hole 3 and the front crossbeam of the vehicle body, it works in conjunction to delay the deformation of the front of the vehicle, protect the front accessories and the main body structure, and improve collision safety. The positioning pins of accessory mounting components 2 assist in assembly and bolt tightening, ensuring that the front accessories are installed accurately and securely. During driving, on bumpy roads and at high speeds, the accessories are subjected to vibration loads. Due to the accurate mounting hole positions and tight connections, loosening and displacement can be effectively avoided, ensuring the normal function of the accessories, such as stable headlight illumination angle and accurate radar detection.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
