Description

Technical Field

[0001] This utility model relates to the field of automotive sealing technology, and in particular to an A-pillar inner cavity partition structure. Additionally, this utility model also relates to a vehicle. Background Technology

[0002] The A-pillar of a car typically uses an interlocking structure of an inner and outer A-pillar panel, forming a through-cavity inside the A-pillar. To improve the structural strength of the A-pillar or to reduce its sound insulation or sealing effect, reinforcing plates, sealing partitions, and other components are usually installed inside the A-pillar cavity.

[0003] In existing technologies, a partition plate is usually installed at the lower part of the A-pillar cavity for sealing and partitioning. The traditional structure uses a method of fixing the plate to the side wall of the A-pillar cavity, such as fixing it to the front door lower hinge mounting plate. This method requires openings in the side wall. The partition plate is installed to the opening with fasteners. As a result, the opening position is prone to air and water leakage, resulting in poor sealing effect of the partition structure. Utility Model Content

[0004] In view of this, the present invention aims to propose an A-pillar inner cavity partition structure to improve the sealing effect of the partition structure in the A-pillar inner cavity.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] An A-pillar cavity partition structure includes a support frame and a partition plate disposed in the A-pillar cavity;

[0007] The support frame is fixed to the inner wall of the A-pillar cavity, and the partition plate overlaps the top of the support frame; the four edges of the partition plate are sealed to the inner wall of the A-pillar cavity to divide the A-pillar cavity into upper and lower parts.

[0008] Furthermore, the top of the support frame has mounting holes arranged along the vertical direction of the vehicle, and the partition plate is fixed to the support frame through the mounting holes.

[0009] Furthermore, the support frame includes a side connecting plate for connecting to the inner wall of the A-pillar cavity, and a mounting plate bent into shape on the top of the side connecting plate; the mounting hole is formed on the mounting plate.

[0010] Furthermore, the partition plate includes an upper plate and a lower plate arranged in a staggered manner, and a transition plate that is inclinedly connected between the upper plate and the lower plate; the upper plate overlaps the support frame.

[0011] Furthermore, the partition plate includes a skeleton plate and an adhesive disposed on the skeleton plate; the adhesive is disposed at least at the edge of the skeleton plate, and the adhesive forms a seal between the skeleton plate and the inner wall of the A-pillar cavity.

[0012] Furthermore, the edge of the skeleton plate is provided with a sealing groove, and the adhesive located at the edge of the skeleton plate is injected or foamed into the sealing groove.

[0013] Furthermore, the skeleton plate is integrally formed with a locking protrusion, and the partition plate is locked onto the support frame through the locking protrusion.

[0014] Furthermore, on the other side of the skeleton plate, a molding groove is formed relative to the side where the locking protrusion is located; the colloid is injected or foamed into the molding groove.

[0015] Furthermore, the skeleton plate is also provided with a connecting groove, which connects the molding groove and the sealant groove, and the sealant is injected or foamed in the connecting groove; the sealant groove, the molding groove and the sealant in the connecting groove are connected as one unit.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] The A-pillar cavity partition structure of this utility model uses a support frame installed on the inner wall of the A-pillar cavity to attach the partition plate to the support frame. The perimeter of the partition plate is specifically responsible for sealing the A-pillar cavity, avoiding the presence of holes at the edges of the partition plate for connection and fixation with the A-pillar cavity. This reduces air and water leakage between the partition plate and the inner wall, and improves the sealing effect of the partition structure in the A-pillar cavity.

[0018] In addition, mounting holes are provided at the top of the support frame. After the partition plate is erected on the top of the support frame, it can be firmly fixed to the support frame by fasteners, snap-fit ​​structures, etc. This can effectively prevent the partition plate from shaking or shifting in the A-pillar cavity. This not only helps to ensure the stability of the sealing and partitioning performance of the partition plate, but also provides strong support for the side wall of the A-pillar (i.e., the inner wall of the A-pillar cavity), thereby improving the structural strength of this part of the A-pillar.

[0019] In addition, the partition plate adopts a Z-shaped cross-section structure, with the upper and lower plates staggered vertically. The transition plate is inclined to achieve a transition connection between the upper and lower plates, which can increase the support distance of the partition plate to the side wall of the A-pillar in the height direction. Moreover, since the A-pillar is usually formed by the interlocking of the inner and outer A-pillar plates, the bending part between the upper plate and the transition plate (or the transition plate and the lower plate) is set to correspond to the fitting position of the inner and outer A-pillar plates. By setting the outward protruding sharp corner structure at the bending part, not only is the structural strength of the bending part improved, but the sharp corner structure can also be inserted into the fitting position between the inner and outer A-pillar plates. With the addition of sealing adhesive, the sealing effect of this part can be effectively guaranteed.

[0020] Another objective of this invention is to provide a vehicle in which the A-pillar is provided with the A-pillar internal cavity partition structure described in this invention. The vehicle of this invention possesses the technical advantages of the aforementioned A-pillar internal cavity partition structure. Attached Figure Description

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] Example 1

[0039] This embodiment relates to an A-pillar inner cavity partition structure, which can improve the sealing effect of the partition structure in the A-pillar inner cavity 10; an exemplary structure is as follows: Figure 1 , Figure 2 and Figure 3 As shown.

[0040] Overall, the A-pillar cavity partition structure includes a support frame 2 and a partition plate 3 disposed in the A-pillar cavity 10; the support frame 2 is fixedly mounted on the inner wall of the A-pillar cavity 10, and the partition plate 3 overlaps the top of the support frame 2; the four edges of the partition plate 3 are sealed to the inner wall of the A-pillar cavity 10 to divide the A-pillar cavity 10 into upper and lower parts.

[0041] It should be noted that, based on the above-mentioned overall design concept, the technical solution of this utility model can adopt a variety of different specific implementation structures, forms, or configuration sequences. For example, the support frame 2 and A-column 1, and the partition plate 3 and support frame 2 can adopt different specific connection structures such as welding, screwing, and snap-fitting; the specific arrangement sequence and assembly method of A-column 1, support frame 2, and partition plate 3 can also be flexibly adjusted. For parts required for the implementation of the overall solution but not involved in the above overall setup, reasonable and flexible design can be carried out by referring to mature setup methods in the field and the actual situation during implementation. The specific implementation scheme described below in this embodiment is only one of the many solutions that can be formed by the above-mentioned combinations and variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the many solutions that can be formed by the above-mentioned combinations and variations, as well as the specific implementation scheme of this embodiment, are all within the protection scope of this utility model.

[0042] Specifically, in this embodiment, combined with Figure 4As shown, the top of the support frame 2 has mounting holes 210 arranged along the vertical direction of the vehicle, and the partition plate 3 is fixed to the support frame 2 through the mounting holes 210. With mounting holes 210 on the top of the support frame 2, after the partition plate 3 is placed on top of the support frame 2, it can be firmly fixed to the support frame 2 by means of fasteners, snap-fit ​​structures, etc., which can effectively prevent the partition plate 3 from shaking or shifting in the A-pillar cavity 10. This not only helps to ensure the stability of the sealing and partitioning performance of the partition plate 3, but also provides strong support for the side wall of the A-pillar 1 (i.e., the inner wall of the A-pillar cavity 10), thereby improving the structural strength of this part of the A-pillar 1.

[0043] There are, of course, various structural options available for the support frame 2. In this embodiment, the support frame 2 includes a side connecting plate 20 for connecting to the inner wall of the A-pillar cavity 10, and a mounting plate 21 bent into shape on the top of the side connecting plate 20; the aforementioned mounting hole 210 is formed on the mounting plate 21. Figure 4 As shown, since the support frame 2 in this embodiment is fixed to the outer A-pillar panel 12 of the A-pillar 1, the top of the side connecting plate 20 has a certain size in the vehicle's longitudinal direction. Therefore, it is suitable to distribute multiple mounting holes 210 at intervals along the vehicle's longitudinal direction on the mounting plate 21. In order to reduce the overall area of ​​the mounting plate 21 and save materials, two mounting plates 21 are arranged at intervals in the vehicle's longitudinal direction in this embodiment, and each mounting plate 21 has one mounting hole 210.

[0044] The shape of the mounting hole 210 can be circular, oriented, or other shapes, depending on the connection structure on the partition plate 3. The support frame 2 is designed as an "L"-shaped bent structure, which facilitates processing and construction. The side connecting plate 20 is fixed to the inner wall of the A-pillar cavity 10 by welding, screwing, or other methods. The mounting plate 21 is horizontal and is used to support the installation of the partition plate 3. This provides good installation conditions for the installation and fixation of the partition plate 3 and forms a stable support for the partition plate 3.

[0045] The specific shape of the partition plate 3 can, of course, be a flat plate. However, in this embodiment, as... Figures 5 to 8 As shown, the partition plate 3 includes an upper plate 3a and a lower plate 3c arranged in a staggered manner, and a transition plate 3b inclinedly connected between the upper plate 3a and the lower plate 3c; the upper plate 3a overlaps the support frame 2. The specific dimensions of each plate can be flexibly set; for example, in this embodiment, the height difference between the upper plate 3a and the lower plate 3c is 42mm, and the transition plate 3b is inclined at a 110° angle relative to the lower plate 3c.

[0046] The partition plate 3 adopts a Z-shaped cross-section structure, with the upper plate 3a and the lower plate 3c staggered vertically. The transition plate 3b is inclined to achieve the transition connection between the upper plate 3a and the lower plate 3c, which can increase the support distance of the partition plate 3 to the side wall of the A-pillar 1 in the height direction. Moreover, since the A-pillar 1 is usually formed by the inner plate 11 and the outer plate 12 of the A-pillar, the bending part between the upper plate 3a and the transition plate 3b (or the transition plate 3b and the lower plate 3c) is set to correspond to the fitting position of the inner plate 11 and the outer plate 12 of the A-pillar. By setting the outward protruding sharp corner structure at the bending part, not only is the structural strength of the bending part improved, but the sharp corner structure can also be inserted into the fitting position between the inner plate 11 and the outer plate 12 of the A-pillar. With the addition of the sealing adhesive, the sealing effect of this part can be effectively guaranteed.

[0047] At the same time, combined Figure 3 As shown, in this embodiment, a reinforcing plate 110 is provided on the inner A-pillar panel 11. The reinforcing plate 110 is attached to the inner side of the inner A-pillar panel 11 and is located directly above the partition plate 3. The reinforcing plate 110 provides structural reinforcement to the A-pillar 1, improving its ability to withstand impacts from the vehicle's front and rear directions. Furthermore, this location on the inner A-pillar panel 11 is typically where the door hinges are installed. The reinforcement by the reinforcing plate 110 provides a stable mounting base for the door hinges. Because the positions of the reinforcing plate 110 and the partition plate 3 partially overlap, the partition plate 3 is designed with a "Z" shape. The lower plate 3c is positioned lower than the upper plate 3a, effectively avoiding the reinforcing plate 110. This allows the lower plate 3c to directly abut against the body of the inner A-pillar panel 11, ensuring a tight seal between the partition plate 3 and the inner A-pillar panel 11.

[0048] Depend on Figure 6 As can be seen, by setting the partition plate 3, the A-pillar cavity 10 is divided into two parts: the upper cavity 101 and the lower cavity 100. The two cavities are completely isolated by the partition plate 3, which can prevent water in the upper cavity 101 from leaking into the lower cavity 100, and also prevent airflow noise in the A-pillar cavity 10.

[0049] Because the partition plate 3 adopts a bent structure, the upper plate 3a overlaps with the mounting plate 21, and the transition plate 3b is located on one side of the mounting plate 21. The support frame 2 and the partition plate 3 form a more stable structural fit in three-dimensional space. The partition plate 3 can be fixed to the support frame 2 first, and then the support frame 2 and the partition plate 3 can be installed as a whole into the inner cavity 10 of the A-pillar. The support frame 2 is fixed to the outer plate 12 of the A-pillar by spot welding from the outside of the outer plate 12, thus completing the installation of the partition structure in the inner cavity of the A-pillar.

[0050] To ensure the airtightness of partition plate 3, such as Figure 4 As shown, the partition plate 3 of this embodiment includes a skeleton plate 30 and an adhesive 31 disposed on the skeleton plate 30; and the adhesive 31 is provided at least at the edge of the skeleton plate 30, and the adhesive 31 at the edge forms a seal between the skeleton plate 30 and the inner wall of the A-pillar cavity 10. By providing the adhesive 31 at the periphery of the skeleton plate 30, the adhesive 31 is tightly clamped between the inner wall of the A-pillar cavity 10 and the skeleton plate 30, thereby forming a reliable seal and ensuring the sealing and partitioning performance of the partition plate 3.

[0051] Furthermore, in this embodiment, a sealing groove 300 is provided at the edge of the skeleton plate 30, and the adhesive 31 located at the edge of the skeleton plate 30 is injected or foamed into the sealing groove 300. By providing a sealing groove 300 at the edge of the skeleton plate 30, and using an injection or foaming molding process to directly place the adhesive 31 into the sealing groove 300, a sandwich panel structure is formed. This not only ensures the firmness of the adhesive 31 on the skeleton plate 30, but also helps to reduce the assembly difficulty of the partition plate 3, and can form a reliable seal between the skeleton plate 30 and the A-pillar cavity 10.

[0052] Based on the structure of the skeleton plate 30, several locking protrusions 32 can be integrally formed on the skeleton plate 30 to facilitate the mounting of the partition plate 3 onto the support frame 2 via the locking protrusions 32. For example... Figure 7 As shown, for the case where the support frame 2 has two mounting holes 210, two locking protrusions 32 can be correspondingly provided on the upper plate 3a. By providing locking protrusions 32 on the frame plate 30 and engaging with the mounting holes 210 on the mounting plate 21, the assembly efficiency of the partition plate 3 in the A-pillar cavity 10 can be improved, and the installation operation can be made more convenient.

[0053] In the case where the retaining protrusion 32 is integrally formed on the skeleton plate 30, a recessed molding groove 301 appears on the upper surface of the skeleton plate 30. A colloid 31 is injected or foamed into the molding groove 301 to prevent air leakage or water seepage at the retaining protrusion 32. Therefore, relative to the side where the retaining protrusion 32 is located, a molding groove 301 is formed on the other side surface of the skeleton plate 30 in this embodiment; simultaneously, a colloid 31 is injected or foamed into the molding groove 301.

[0054] Based on the above configuration, the skeleton plate 30 of this embodiment is also provided with a connecting groove 302, which connects the molding groove 301 and the sealing glue groove 300. Furthermore, the connecting groove 302 is also filled with injected or foamed colloid 31. In this way, the sealing glue groove 300, the molding groove 301, and the colloid 31 in the connecting groove 302 are connected as a whole. Connecting the molding groove 301 and the sealing glue groove 300 at the edge of the skeleton plate 30 through the connecting groove 302 allows the colloid 31 on the skeleton plate 30 to form a connected whole. This facilitates the flow of liquid colloid through the connecting groove 302 and the sealing glue groove 300 during injection or foaming, thereby filling the sealing glue groove 300, the connecting groove 302, and the molding groove 301, ensuring the molding effect of the colloid 31, and thus guaranteeing the sealing effect of the colloid 31 on the partition plate 3.

[0055] In summary, the A-pillar cavity partition structure of this embodiment, by installing a support frame 2 on the inner wall of the A-pillar cavity 10 and attaching the partition plate 3 to the support frame 2, ensures that the periphery of the partition plate 3 is specifically responsible for sealing the A-pillar cavity 10. This avoids the presence of holes at the edges of the partition plate 3 for connection and fixation with the A-pillar cavity 10, thereby reducing air permeability and water leakage between the partition plate 3 and the inner wall, and improving the sealing effect of the partition structure in the A-pillar cavity 10.

[0056] Example 2

[0057] This embodiment relates to a vehicle in which the A-pillar 1 is provided with the A-pillar cavity partition structure provided in Embodiment 1. For example... Figure 1 An exemplary side door frame skeleton is shown, with A-pillar 1 located at the front of the side door frame skeleton. A-pillar 1 is formed by fastening together an outer A-pillar panel 12 and an inner A-pillar panel 11, thereby forming an inner cavity 10 between the inner A-pillar panel 11 and the outer A-pillar panel 12. The inner cavity partition structure of the present invention is set in the inner cavity 10 of the A-pillar.

[0058] By adding a support frame 2 inside the A-pillar cavity 10 and overlapping and fixing the partition plate 3 to the support frame 2 in the vertical direction of the vehicle, the problems of difficult sealing at the edges and high risk of water leakage in traditional laminated panels are solved. It should be noted that the A-pillar cavity partition structure of this utility model is designed to avoid installation holes near the edges of the partition plate 3, which would affect the sealing and partitioning effect of the partition plate 3. Therefore, when setting the partition plate 3, the distribution of holes on the inner wall of the A-pillar cavity 10 should be considered. Taking foamed adhesive as an example, the distance between the edges of the holes (excluding electrophoresis holes and leakage holes) on the inner A-pillar panel 11 and outer A-pillar panel 12 and the foamed material should be more than 15mm, and the distance between the holes and the edges of the skeleton plate 30 should be more than 10mm to ensure a good sealing effect.

[0059] The above description is merely a preferred embodiment of this utility model. Detailed explanations of configurations, examples of specific structural arrangements, and descriptions of assembly and connection methods are provided to ensure sufficient disclosure so that those skilled in the art can better implement this utility model, and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
