Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a spare tire mounting beam assembly. Background Technology

[0002] In the automotive manufacturing industry, the spare tire mounting beam is a key component that ensures reliable spare tire installation, improves vehicle driving safety, and optimizes space utilization. However, as automotive requirements for lightweighting, structural strength, and assembly precision continue to increase, existing spare tire mounting beam assemblies are gradually becoming inadequate.

[0003] In existing technologies, spare tire mounting beams often employ simple frames or spliced ​​structures, which present the following problems: First, it is difficult to balance structural strength and lightweighting. Traditional steel materials or structural designs result in heavy beams, increasing the overall vehicle load, or insufficient strength, making them prone to deformation when bearing the spare tire for extended periods and dealing with vehicle vibrations and impacts, affecting the reliability of the spare tire's fixation. Second, assembly precision is poor, and the design of the connection and positioning structures for each component is imperfect, making it easy for deviations to occur during installation. This leads to poor stability after the spare tire is installed, which may cause abnormal noises, spare tire displacement, or even affect the safety of the entire vehicle while driving. Third, the compatibility with spare tires and surrounding components is limited, making it difficult to meet the spare tire installation requirements of different vehicle models. Furthermore, it performs poorly in terms of load distribution and fatigue resistance, and after long-term use, the beam is prone to cracks and other failures due to stress concentration.

[0004] The existing spare tire mounting beam assembly still has the following problems during use: insufficient structural strength, making it prone to deformation under the weight of the spare tire and the impact of vehicle driving; poor assembly precision, making it easy for deviations to occur between components, affecting the stability of the spare tire; unreasonable load distribution, stress concentration leading to low fatigue resistance and short service life of the beam; and weak adaptability and poor versatility to spare tires and accessories of different models. Utility Model Content

[0005] (a) Technical problems to be solved.

[0006] To address the shortcomings of existing technologies, this utility model provides a spare tire mounting beam assembly. By setting up a main beam frame, reinforcing support arms, end connecting supports, precise positioning, and structural reinforcement, it solves the problems of insufficient structural strength, poor assembly accuracy, unreasonable load distribution, and weak adaptability in the prior art.

[0007] (ii) Technical solution.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a spare tire mounting beam assembly, including a main beam frame, wherein two spare tire mounting seats are symmetrically and fixedly connected to the front end of the main beam frame for supporting and fixing the spare tire, and providing a mounting foundation for the spare tire.

[0009] The main frame of the crossbeam has supporting protrusions at both ends to enhance the structural strength of the crossbeam ends, adapt to vehicle body installation, and assist in load bearing. A reinforcing support arm is fixedly installed at the bottom of the main frame of the crossbeam through a central positioning fastening pin to strengthen the structural strength of the main frame of the crossbeam and distribute the load generated by the spare tire and vehicle movement. The reinforcing support arm is inclined and has an end connecting bracket fixedly installed at the end away from the main frame of the crossbeam. The end connecting bracket is vertical and its top is fixedly connected to one end of the main frame of the crossbeam. The two work together to achieve a reliable connection between the crossbeam and the vehicle body and ensure installation stability. An end connecting seat is fixedly connected to the other side of the bottom of the main frame of the crossbeam to assist in the connection between the crossbeam and the vehicle body and optimize the force transmission path.

The spare tire mounting base has a waist-shaped hole at the bottom front end to provide installation adjustment margin and adapt to different installation needs. The spare tire mounting base has a first mounting hole at the top and a second mounting hole on the side. Through the multi-directional hole design, a stable connection between the spare tire and the crossbeam is achieved.

[0011] As a further improvement of this utility model: a main positioning pin is fixedly installed at the bottom end of the main frame of the crossbeam and on one side of the central positioning fastening pin. This pin plays a major positioning role during the installation of the crossbeam, ensuring the installation accuracy of the crossbeam and other components such as the vehicle body.

[0012] As a further improvement of this utility model, an auxiliary positioning pin is fixedly installed on the other side of the positioning fastening pin at the bottom and center of the main frame of the crossbeam, which assists the main positioning pin in positioning, further improving the positional accuracy of the crossbeam after installation and ensuring stable force transmission.

[0013] As a further improvement of this utility model: the bottom wall of the main frame of the crossbeam is provided with a first transverse reinforcing rib groove at both ends, and the bottom center of the reinforcing support arm is provided with a second transverse reinforcing rib groove. Through the reinforcing rib groove design, the weight of the crossbeam can be optimized while ensuring the structural strength, improving the resistance to deformation and fatigue, and effectively distributing the load.

[0014] As a further improvement of this utility model, the front and rear ends of the reinforcing support arm are provided with central load-dispersing ribs to enhance the structural strength of the reinforcing support arm, further disperse the load generated by the spare tire and vehicle movement, avoid stress concentration, and improve the overall fatigue resistance of the crossbeam.

[0015] As a further improvement of this utility model: a central strip adapter hole is provided at the bottom center of the main frame of the crossbeam, which provides adjustment space for the installation of the crossbeam and its adaptation to other components, improves the versatility of the crossbeam for different vehicle models, and facilitates the installation of connecting parts or adaptation to the vehicle body structure.

[0016] As a further improvement of this utility model, the front and rear side walls below the end connecting support are provided with end assembly positioning holes for precise assembly of the end connecting support with the vehicle body and other components, controlling installation tolerances and ensuring the stability of the crossbeam after overall installation.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, the coordinated design of the main frame of the crossbeam, the reinforced support arm, and the end connecting support, along with the main positioning pin, auxiliary positioning pin, reinforcing rib groove, and load-distributing rib plate, significantly improves the structural strength and deformation resistance of the crossbeam. When bearing the weight of the spare tire and the impact of vehicle driving, it can effectively distribute the load, avoid stress concentration, solve the problems of insufficient structural strength and easy deformation in the prior art, ensure the long-term reliable installation of the spare tire, and improve the overall vehicle safety.

[0019] 2. In this utility model, by setting precise positioning structures such as assembly holes, waist-shaped holes, end assembly positioning holes, main positioning pins, and auxiliary positioning pins, as well as the adjustment design of the middle strip adapter hole, the assembly accuracy and versatility of the crossbeam are greatly improved. Precise positioning can be achieved during installation, reducing deviations between components, adapting to the spare tire and body installation needs of different vehicle models, solving the problems of poor assembly accuracy and weak adaptability in existing technologies, and optimizing the stability of spare tire installation and the overall vehicle assembly efficiency.
