Description

Technical Field

[0001] This application relates to the field of automotive component technology, and in particular to an integrated structure for an automotive air conditioning inlet. Background Technology

[0002] With the increasing popularity of automobiles, users' demands for cabin comfort have grown exponentially, prompting air conditioning systems to iterate and upgrade towards higher power and greater capacity. Under this trend, the design of the integrated structure of the air conditioning intake faces unprecedented challenges, needing to meet the physical requirements of high-volume airflow while adapting to the increasingly compact cabin space. However, the air conditioning intake architecture currently used in mainstream automobiles reveals systemic flaws due to the superposition of multiple technical contradictions.

[0003] Traditional solutions typically integrate the air conditioning intakes into the upper part of the front bulkhead, a layout that maintained basic functionality in early models. However, when vehicles widened the lower windshield crossbeam to improve collision safety or accommodate more sensors, the space underneath was severely compressed. In this case, the air conditioning ducts that ran through the front compartment were forced to extend downwards into the engine compartment, encroaching on the space available for critical electrical components such as the battery management system and on-board charger.

[0039] Traditional automotive air conditioning intake integration structures typically integrate the air conditioning intake into the upper area of ​​the front bulkhead. This arrangement was sufficient to maintain basic functionality in early models. However, when vehicles widen the lower windshield crossbeam to improve collision safety or accommodate more sensors, the space underneath is severely compressed. In this case, the air conditioning duct running through the front compartment is forced to extend downwards into the engine compartment, encroaching on the space for critical electrical components such as the battery management system and on-board charger. Furthermore, according to current processes, workers must first pre-connect the air conditioning duct to the intake assembly using clips from outside the vehicle, and then crawl into the narrow space under the windshield crossbeam to secure the front end of the duct to the body structure with bolts. During this process, operators must work under extremely limited visibility, making it difficult to guarantee bolt alignment accuracy and significantly reducing assembly efficiency due to distorted working postures.

[0040] The inventors proposed an integrated structure for automotive air conditioning intakes, which moves the air conditioning duct from the front bulkhead to the cavity of the lower windshield crossbeam, achieving spatial overlap between the air intake system and the lower windshield crossbeam, eliminating the encroachment of the air conditioning duct on the space for the arrangement of electrical components in the front compartment; and the operators do not need to crawl under the lower windshield crossbeam to work, and can assemble the air conditioning assembly and air conditioning duct through the open area inside the compartment, reducing the difficulty of installation.

[0041] This application provides an integrated structure for an automotive air conditioning inlet. Please refer to [link / reference]. Figures 1 to 3 The system includes a lower crossbeam 1, a reinforcing beam 2, and a support plate 3. The lower crossbeam 1 has a first air inlet 12. The reinforcing beam 2 is connected to the lower crossbeam 1 and has a second air inlet 21 corresponding to the first air inlet 12. There is a gap between the reinforcing beam 2 and the lower crossbeam 1. The support plate 3 is connected between the lower crossbeam 1 and the reinforcing beam 2. The lower crossbeam 1, the reinforcing beam 2, and the support plate 3 together form an air intake channel, which is connected to the first air inlet 12 and the second air inlet 21, respectively.

[0042] In the above solution, the air conditioning duct 4 passes through the lower crossbeam 1 of the windshield, placing it inside the vehicle cabin. This effectively increases the space available outside the cabin, providing sufficient space for other electrical components. Simultaneously, the installation location of the air conditioning duct 4 offers a wide field of vision, reducing assembly difficulty, improving assembly efficiency, and enhancing overall vehicle precision. The lower crossbeam 1, reinforcing beam 2, and support plate 3 together form the air intake channel, effectively ensuring its strength. Furthermore, the lower crossbeam 1, reinforcing beam 2, and support plate 3 together enclose a relatively closed cavity, further strengthening the support for the air intake channel and resolving the issue of component cracking and abnormal noise.

[0043] In some embodiments, the lower windshield beam 1 includes an angled vertical beam 11 and a horizontal beam 13. The horizontal beam 13 extends along the length of the vertical beam 11 and is connected to the vertical beam 11. Specifically, the horizontal beam 13 and the vertical beam 11 together form the lower windshield beam 1 with an approximately L-shaped longitudinal section. The L-shaped section has a larger moment of inertia, which can provide higher structural strength under the same weight.

[0044] In some embodiments, such as Figure 3 , Figure 4 As shown, the reinforcing beam 2 extends along the length of the lower crossbeam 1 of the windshield. Both ends of the reinforcing beam 2 along its extension direction are connected to the lower crossbeam 1 of the windshield. The upper and lower sides of the reinforcing beam 2 along its height direction are also connected to the lower crossbeam 1 of the windshield. The upper and lower edges of the reinforcing beam 2 at the second air inlet 21 are connected to the lower crossbeam 1 of the windshield, respectively, with a gap between the central area and the reinforcing beam 2. At this point, the crossbeam plate 13, the reinforcing beam 2, and the support plate 3 together constitute the air intake channel, and together they enclose a relatively closed cavity.

[0045] Specifically, the upper and lower edges of the reinforcing beam 2 at the second air inlet 21 are welded to the lower crossbeam 1 of the windshield, so that the support plate 3 only needs to be set on the two side walls of the air inlet channel, thereby reducing the number of assembly parts and improving assembly efficiency.

[0046] More specifically, the reinforcing beam 2 extends along the length of the horizontal beam upright plate 11, and the two ends of the reinforcing beam 2 along the extension direction are welded to the horizontal beam upright plate 11. The upper and lower sides of the reinforcing beam 2 along its own height direction are welded to the horizontal beam upright plate 11. The upper and lower edges of the reinforcing beam 2 at the second air inlet 21 are welded to the horizontal beam upright plate 11 respectively.

[0047] In some embodiments, the two ends of the windshield lower crossbeam 1 along the length direction and the two ends of the reinforcing beam 2 along the length direction are welded together to the same position on the vehicle side wall.

[0048] Specifically, the two ends of the crossbeam upright plate 11 along its length and the two ends of the reinforcing beam 2 along its length are welded together at the same position on the vehicle side wall. By converging and welding the two ends of the crossbeam upright plate 11 and the reinforcing beam 2 to the same point on the vehicle side wall, the material thickness and cross-sectional strength at the weld are significantly increased.

[0049] In some embodiments, such as Figure 5 As shown, the reinforcing beam 2 has serrations 22 spaced along its upper and lower sides along its height direction. The serrations 22 are welded to the lower crossbeam 1 of the windshield. Specifically, the serrations 22 are welded to the crossbeam upright plate 11. It can be understood that the spaced serrations 22 can form equally spaced physical marks, providing operators with intuitive welding targets, eliminating the deviation of visual positioning based on experience, and ensuring that the spacing of the weld points is strictly consistent; at the same time, the serrations 22 can also reduce the overall vehicle weight and reduce the manufacturing cost per vehicle.

[0050] In some embodiments, ribs 23 are provided between adjacent sawtooth 22, and the ribs 23 are spaced apart from each other with the lower crossbeam 1 of the windshield. Specifically, a gap is provided between the ribs 23 and the vertical plate 11 of the crossbeam. It can be understood that the gap between the ribs 23 and the vertical plate 11 of the crossbeam creates a micro-airflow channel in the relatively closed cavity formed by the crossbeam plate 13, the reinforcing beam 2, and the support plate 3, so as to balance the humidity and environment inside the cavity. At the same time, the ribs 23 can enhance the structural strength of the sawtooth 22.

[0051] In some embodiments, the rib 23 includes a body 231 and a connecting portion 232; the body 231 is located on the side of the serration 22 away from the lower crossbeam 1 of the windshield; the connecting portion 232 is disposed on opposite sides of the body 231, and the end of the connecting portion 232 away from the body 231 is connected to the adjacent serration 22. It is understood that, in order to form a gap between the rib 23 and the lower crossbeam 1 of the windshield, the connecting portion 232 and the body 231 are arranged at an angle, and the connecting portion 232 is inclined towards the crossbeam upright plate 11.

[0052] In some embodiments, the second air inlet 21 covers the first air inlet 12, and the flow area of ​​the second air inlet 21 is slightly larger than that of the first air inlet 12. Specifically, both the first air inlet 12 and the first air duct 12 are rectangular, and the size of the first air inlet 12 is adapted to the size of the air conditioning duct 4, which facilitates the installation and assembly of the air conditioning duct 4.

[0053] In some embodiments, the support plate 3 is disposed between the reinforcing beam 2 and the lower crossbeam 1 of the windshield around the air inlet, and has a crossbeam connecting edge and a reinforcing beam connecting edge; the crossbeam connecting edge is connected to the lower crossbeam 1 of the windshield; and the reinforcing beam connecting edge is connected to the reinforcing beam 2.

[0054] Specifically, such as Figure 6As shown, a first bend 31 is provided on the crossbeam connecting edge of the support plate 3. The first bend 31 extends along the crossbeam connecting edge towards the first air inlet 12. The first bend 31 is welded to the crossbeam upright plate 11 to achieve the connection between the crossbeam connecting edge and the lower crossbeam 1 of the windshield. The outer edge of the first bend 31 away from the support plate 3 is located outside the first air inlet 12 to avoid interfering with the installation of the air duct 4.

[0055] Specifically, such as Figure 4 As shown, the supporting plate 3 has a second bend 32 on the reinforcing beam connecting edge. The second bend 32 extends along the reinforcing beam connecting edge away from the second air inlet 21. The second bend 32 is welded to the reinforcing beam 2 to achieve the connection between the reinforcing beam connecting edge and the reinforcing beam 2. The outer edge of the second bend 32 away from the supporting plate 3 is located outside the second air inlet 21.

[0056] Understandably, the support plate 3 has a first bend 31 and a second bend 32 on the crossbeam connecting edge and the reinforcing beam connecting edge, respectively, and the cross-section of the support plate 3 is approximately Z-shaped. During welding, the reinforcing beam 2 and the lower crossbeam 1 of the windshield can be welded to the vehicle body first, and then the support plate 3 can be welded to the reinforcing beam 2 first, and then to the crossbeam upright plate 11, which provides support and reduces the difficulty of welding. In addition, the unique design of the support plate 3 can provide space for the installation of the air conditioning duct 4.

[0057] In some embodiments, such as Figure 1 , Figure 2 As shown, the integrated structure also includes an air conditioning duct 4, an air intake assembly 5, and an air conditioning assembly 6; the air conditioning duct 4 passes through the air intake channel, and the first end of the air conditioning duct 4 is located on the side of the crossbeam vertical plate 11 away from the crossbeam horizontal plate 13, and the second end is located on the side of the crossbeam horizontal plate 13 away from the crossbeam vertical plate 11; the air intake assembly 5 is connected to the first end; the air conditioning assembly 6 is connected to the second end, wherein the first end and the second end are the two opposite ends of the air conditioning duct 4.

[0058] It is understandable that the cross-section of the air conditioning duct 4 can be set to a rectangle, and the first air inlet 12 and the second air inlet 21 can be set to rectangles accordingly. When the cross-sectional shape of the air conditioning duct 4 is set to other shapes, the shapes of the first air inlet 12 and the second air inlet 21 can be adjusted accordingly. For example, when the cross-sectional shape of the air conditioning duct 4 is set to a circle, the first air inlet 12 and the second air inlet 21 are also circular.

[0059] During the assembly process, after welding and fixing the lower crossbeam 1, reinforcing beam 2, and support plate 3 of the windshield, the air conditioning duct 4 and the air conditioning assembly 6 are first fastened together. Then, the operator overlaps the air conditioning duct 4 at the air intake channel inside the cabin and assembles the air conditioning duct 4 and the air conditioning assembly 6 onto the vehicle body by screwing them together. Outside the cabin, the air intake assembly 5 is connected to the air conditioning duct 4 and is also assembled onto the vehicle body by screwing them together, thus completing the installation of the integrated structure of the vehicle air conditioning air intake.
