Description

Technical Field

[0001] This utility model relates to the field of air duct technology, specifically to an integrated aluminum air duct connector for vehicles. Background Technology

[0002] With the accelerating trend of lightweighting in automobiles, especially the demand for longer driving range in electric vehicles, large buses such as public buses are generally using aluminum profiles to replace steel frames in order to reduce weight.

[0003] Referring to existing technologies (such as CN 210454986 U), a vehicle-mounted integrated aluminum air duct connector is disclosed. This connector replaces traditional rivet connections with a hollow design (such as hollow elongated slots and hollow partitions) and an integrated structure, achieving initial weight reduction and convenient installation. However, based on analysis of real-world examples, this patent has the following drawbacks:

[0004] 1. Complex structure and insufficient strength: Although the hollow slot and hollow partition design reduces weight, stress concentration is likely to occur in the crash test, which increases the risk of frame deformation (for example, a bus accident report in a certain city showed that the strength of similar structures decreased by 15% in the side collision).

[0005] 2. Limited functionality: It is only used as an air duct or channel light installation area, without integrating auxiliary functions such as sound insulation and energy absorption, which cannot meet the high requirements of modern buses for comfort and safety (as reported by users, the existing frame exceeds the noise standard when driving at high speed).

[0006] 3. High manufacturing and maintenance costs: Hollow tubes and hollow partitions require precision machining, which increases manufacturing costs; and the energy-absorbing panels are optional configurations, and their non-standardization leads to inconvenience in maintenance (for example, maintenance records of a bus company show that replacing energy-absorbing components takes 30% longer).

[0007] 4. Low thermal management efficiency: The toothed design of the slot plate is simple and has a limited surface area, resulting in poor heat dissipation in high-temperature environments (e.g., in summer tests, the temperature of the air duct increased by 10-15℃).

[0008] Therefore, we have made improvements to the aforementioned existing technologies based on actual usage. Utility Model Content

[0009] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0010] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0018] An energy-absorbing material layer is filled inside the hollow tube. The energy-absorbing material layer is made of aluminum foam and is bonded and fixed to the inner wall of the hollow tube.

[0019] The toothed part of the slot plate has a wavy structure and its surface is coated with a thermally conductive coating.

[0020] The outer edge of the load-bearing column is provided with a serrated edge for fastening with other components;

[0023] Furthermore: the hollowed-out section has a honeycomb structure with a wall thickness of 1-2mm, which is used to reduce weight in non-stressed areas.

[0024] Furthermore, the energy-absorbing material layer accounts for 80%-90% of the volume of the hollow tube, and its density is 0.3-0.5g / cm³, which is used to absorb kinetic energy during collisions.

[0026] Furthermore, the clamping edges are evenly distributed along the length of the force-bearing column, with a spacing of 10-15mm, to enhance the stability of the fastening.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] The honeycomb-shaped perforated section and optimized perforated structure reduce weight, the energy-absorbing material layer improves collision safety, the energy-absorbing material layer provides collision protection, the thermally conductive coating enhances thermal management, and sound insulation materials can be integrated to reduce noise.

[0048] An energy-absorbing material layer 13 is filled inside the hollow tube 9. The energy-absorbing material layer 13 is made of aluminum foam and is bonded and fixed to the inner wall of the hollow tube 9.

[0049] The toothed part 10 of the slot plate has a wavy structure and its surface is coated with a thermally conductive coating 14.
