Description

Technical Field

[0001] This utility model relates to the field of aluminum honeycomb panel technology, specifically to a deformation-resistant support structure for lightweight aluminum honeycomb panels. Background Technology

[0002] Aluminum honeycomb panels are a new type of environmentally friendly material, composed of two layers of aluminum sheets and an aluminum honeycomb core in the middle. They offer advantages such as light weight, high strength, sound insulation, and heat insulation, and are widely used in building curtain walls, interior decoration, and furniture manufacturing. However, in actual use, due to the structural characteristics of aluminum honeycomb panels, they are prone to deformation under external forces, affecting their performance and service life.

[0003] Currently, the common methods for supporting aluminum honeycomb panels against deformation are to increase the thickness of the aluminum plate or to densify the aluminum honeycomb core. However, this increases the weight of the aluminum honeycomb panel, negating its lightweight advantage, and also increases production costs.

[0004] Therefore, we proposed a deformation-resistant support structure for lightweight aluminum honeycomb panels to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a deformation-resistant support structure for lightweight aluminum honeycomb panels, in order to solve the problem that the existing methods of deformation-resistant support for aluminum honeycomb panels in the market, as mentioned in the background art, lead to an increase in the weight of the aluminum honeycomb panels, thus losing their lightweight advantage, and also increasing production costs.

[0006] This utility model provides the following technical solution: a deformation-resistant support structure for lightweight aluminum honeycomb panels, comprising an upper aluminum plate and a lower aluminum plate, both the upper and lower aluminum plates having slots, and both the upper and lower aluminum plates having sidewalls fixed with clamping plates, the upper aluminum plate having an upper cavity, the lower aluminum plate having a lower cavity, a transverse support strip installed in the lower cavity, a longitudinal support strip installed in the upper cavity, an upper placement groove in the upper aluminum plate, and a lower placement groove in the lower aluminum plate, with aluminum honeycomb core panels clamped in the upper and lower placement grooves.

[0007] Preferably, the card slot is provided with an adhesive layer, the card plate is adapted to the card slot, the card plate is snapped into the card slot, and the card plate is attached to the upper aluminum plate through the adhesive layer.

[0008] Preferably, multiple transverse and longitudinal support bars are arranged in a linear distribution.

[0009] Preferably, the transverse support bars and longitudinal support bars are intersected and connected to form a grid structure.

[0010] Preferably, a wedge-shaped strip is symmetrically fixed on the bottom surface of the upper aluminum plate, and a wedge-shaped groove is symmetrically opened on the top surface of the lower aluminum plate. The wedge-shaped strip is adapted to the wedge-shaped groove, and the wedge-shaped strip and the wedge-shaped groove are engaged.

[0011] Preferably, the honeycomb cells of the aluminum honeycomb core panel have a regular hexagonal structure.

[0012] This utility model has the following beneficial effects:

[0013] 1. This anti-deformation support structure achieves precise snap-fitting of the aluminum honeycomb core panel through upper and lower placement slots, replacing the traditional method of densifying the aluminum honeycomb core to enhance stability. Combined with polished slot walls, it avoids surface scratches during core panel installation and eliminates the welding process through the snap-fit ​​method, protecting the original geometric stability of the hexagonal honeycomb cells and ensuring its axial compressive strength is not compromised. It eliminates the need to increase core density to improve strength, effectively controlling material usage while maintaining fundamental anti-deformation performance, thus avoiding the increased weight and cost associated with core densification.

[0014] 2. This anti-deformation support structure achieves a stable connection between the upper and lower aluminum plates through a wedge-shaped strip and wedge-shaped groove matching mechanism. Its self-locking characteristic effectively prevents relative displacement during use. Compared with traditional snap-fit ​​solutions, it improves structural stability without requiring increased aluminum plate thickness to enhance splicing strength. This design without additional connectors avoids damage to the aluminum plate structure caused by openings and eliminates the problem of increased weight due to thicker aluminum plates or added fasteners. While ensuring connection strength, it perfectly preserves the lightweight core advantage of aluminum honeycomb panels, reducing material costs and transportation and installation costs.

[0015] 3. This anti-deformation support structure innovatively constructs a composite mechanical structure with two-way support and three-dimensional pressure bearing through the synergistic effect of a grid-like support system and a regular hexagonal honeycomb core panel. It replaces the traditional approach of relying on thickened aluminum plates or denser cores for anti-deformation, without sacrificing lightweight characteristics for anti-deformation capabilities. It achieves performance upgrades while reducing material consumption, and solves the problem of the difficulty in balancing lightweight and anti-deformation. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] This embodiment aims to facilitate a solution to multiple problems existing in traditional aluminum honeycomb panels regarding structural stability, assembly precision, and lightweight balance. Please refer to [link / reference]. Figure 1 - Figure 4 The deformation-resistant support structure of the lightweight aluminum honeycomb panel includes an upper aluminum plate 1 and a lower aluminum plate 2. The upper aluminum plate 1 and the lower aluminum plate 2 are still made of high-strength aluminum alloy, taking into account both strength and lightweight requirements. An upper cavity 12 is opened in the upper aluminum plate 1, and a lower cavity 6 is opened in the lower aluminum plate 2. A transverse support bar 7 is installed in the lower cavity 6. The lower cavity 6 inside the lower aluminum plate 2 extends along the length direction, and the cross-sectional dimensions are the same as those of the upper cavity 12, ensuring that the transverse support bar 7 forms a stable force-bearing system with the aluminum plate structure after installation. A longitudinal support bar 14 is installed in the upper cavity 12. The upper cavity 12 opened in the upper aluminum plate 1 extends along the width direction, and the cross-section is rectangular. The length of the cavity is the same as the width of the upper aluminum plate 1, providing precise installation space for the longitudinal support bar 14.

[0024] An upper placement groove 13 is formed in the upper aluminum plate 1, and a lower placement groove 8 is formed in the lower aluminum plate 2. An aluminum honeycomb core panel 10 is snapped into the upper placement groove 13 and the lower placement groove 8. The honeycomb holes of the aluminum honeycomb core panel 10 have a regular hexagonal structure. The regular hexagonal structure of the honeycomb holes has good mechanical properties and can disperse the pressure in the vertical direction through the geometric stability of the honeycomb holes. Placing the anti-deformation support component at the connection can further improve the structural stability of the aluminum honeycomb core. The cross-section of both the upper placement groove 13 and the lower placement groove 8 is rectangular, matching the edge of the aluminum honeycomb core panel 10. The inner sidewalls of the upper placement groove 13 and the lower placement groove 8 are polished, with smooth surfaces to avoid scratching the surface of the aluminum honeycomb core panel 10 during installation.

[0025] Multiple horizontal support bars 7 and vertical support bars 14 are linearly distributed and interconnected to form a grid structure. The horizontal support bars 7, made of high-strength aluminum alloy with a rectangular cross-section, are installed within the lower cavity 6. They are fixed to the inner wall of the lower cavity 6 via laser welding, ensuring connection strength while minimizing thermal damage to the aluminum plate. The vertical support bars 14, made of the same material and with the same dimensions as the horizontal support bars 7, are installed within the upper cavity 12 and fixed using the same laser welding process. They are linearly and evenly distributed along the width of the upper aluminum plate 1, with the spacing consistent with that of the horizontal support bars 7. The horizontal support bars 7 and vertical support bars 14 are bonded to both sides of the aluminum honeycomb core panel 10, forming a complete grid-like support system with uniform grid node spacing, ensuring uniform distribution of external forces.

[0026] A wedge-shaped strip 11 is symmetrically fixed on the bottom surface of the upper aluminum plate 1, and a wedge-shaped groove 9 is symmetrically opened on the top surface of the lower aluminum plate 2. The wedge-shaped strip 11 is adapted to the wedge-shaped groove 9, and the wedge-shaped strip 11 and the wedge-shaped groove 9 are engaged.

[0027] In this embodiment: First, the transverse support strip 7 is fixed to the lower cavity 6 of the lower aluminum plate 2 by laser welding, and the longitudinal support strip 14 is fixed to the upper cavity 12 of the upper aluminum plate 1 by the same laser welding process. During laser welding, the diameter of the welding point is controlled within two millimeters, and the distance between adjacent welding points is maintained at five to eight centimeters. This design can ensure the connection strength between the transverse support strip 7 and the inner wall of the lower cavity 6, and between the longitudinal support strip 14 and the inner wall of the upper cavity 12, while minimizing thermal damage to the aluminum plate during the welding process, and avoiding the aluminum plate from affecting the overall structural accuracy due to thermal deformation. At the same time, fixing the support strips in advance can ensure the positional accuracy of the grid support system during subsequent assembly, laying the foundation for the overall anti-deformation performance.

[0028] After the support strips are installed, the upper and lower edges of the aluminum honeycomb core panel 10 are aligned with the upper placement groove 13 of the upper aluminum plate 1 and the lower placement groove 8 of the lower aluminum plate 2, respectively, so that the aluminum honeycomb core panel 10 is precisely inserted into them. Since the inner walls of the upper placement groove 13 and the lower placement groove 8 are polished and have smooth surfaces, scratches on the surface of the aluminum honeycomb core panel 10 can be avoided during the insertion process. After insertion, the aluminum honeycomb core panel 10 and the contact parts of the placement grooves naturally fit together without additional welding operations. This allows for the rapid initial positioning of the aluminum honeycomb core panel 10 and the upper and lower aluminum plates 2. The precise matching of the placement grooves with the edges of the aluminum honeycomb core panel 10 ensures the verticality and flatness of the core panel installation. At the same time, avoiding welding operations prevents high temperatures from damaging the hole wall structure of the aluminum honeycomb core panel 10, protects the geometric stability of the regular hexagonal honeycomb holes, and ensures that it can effectively disperse the vertical pressure through the axial bearing effect of the hole walls.

[0029] After the aluminum honeycomb core panel 10 is snapped together, the wedge-shaped strip 11, which is symmetrically fixed on the bottom surface of the upper aluminum plate 1, is aligned with the wedge-shaped groove 9, which is symmetrically opened on the top surface of the lower aluminum plate 2. This allows the wedge-shaped strip 11 to precisely engage with the wedge-shaped groove 9, completing the splicing of the upper and lower aluminum plates 2. This achieves rapid positioning and initial fixation of the upper and lower aluminum plates 2. The wedge structure has a self-locking characteristic, which can prevent relative displacement of the upper and lower aluminum plates 2 during subsequent assembly or use, ensuring the stability of the overall structure. At the same time, this snap-fit ​​method does not require additional connectors and does not increase the structural weight, meeting the requirements of lightweight design.

[0030] Example 2:

[0031] This embodiment aims to address the problems of low positioning accuracy, insufficient connection strength, and poor gap sealing when splicing multiple aluminum honeycomb panels. This embodiment is an improvement upon Embodiment 1. For details, please refer to [link to Embodiment 1]. Figure 1 - Figure 2 Both the upper aluminum plate 1 and the lower aluminum plate 2 have slots 3, and each upper aluminum plate 1 and lower aluminum plate 2 has a clamping plate 5 fixed to its side wall. An adhesive layer 4 is provided inside the slot 3. The clamping plate 5 fits into the slot 3, and the clamping plate 5 and slot 3 are snapped together. The clamping plate 5 and upper aluminum plate 1 are then bonded together via the adhesive layer 4. The adhesive layer 4 inside the slot 3 uses a modified acrylic adhesive, with a coating width consistent with the top width of the slot 3, exhibiting good weather resistance and water resistance. During installation, first clean the oil and dust from the slot 3 and clamping plate 5. After the clamping plate 5 is fully inserted into the slot 3, apply pressure and hold for a period of time to ensure that the adhesive layer 4 makes full contact and initially cures.

[0032] In this embodiment: According to actual usage requirements, multiple aluminum honeycomb panels are assembled. During assembly, the clips 5 on the side walls of the upper aluminum plate 1 and lower aluminum plate 2 of one aluminum honeycomb panel are aligned with the corresponding slots 3 of another aluminum honeycomb panel. After cleaning the oil and dust from the slots 3 and the surface of the clips 5, the clips 5 are fully inserted into the slots 3. Then, pressure is applied and maintained for a period of time to ensure that the modified acrylic adhesive layer 4 in the slots 3 is in full contact and initially cured.

[0033] The matching snap-fit ​​connection between the card plate 5 and the card slot 3, combined with the adhesive layer 4, solves the problems of low positioning accuracy and insufficient connection strength when splicing multiple aluminum honeycomb panels. The modified acrylic adhesive has good weather resistance and water resistance, ensuring long-term stability and sealing at the splice joint, achieving good dustproof and waterproof effects. At the same time, the assembly process is simple and can be operated by a single person, improving installation efficiency and avoiding the stress concentration problem caused by traditional bolt connections.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
