[0002] The multi-functional bracket is a key component used in automotive diesel engines. It integrates multiple functions such as engine mounting bracket, air conditioner bracket, and generator bracket. The bracket has a compact structure and high strength, which can effectively support and fix various engine accessories, reduce system vibration, and improve the overall vehicle operation stability.

[0003] Existing multi-functional brackets can effectively support and fix various engine accessories, reduce system vibration, and improve the overall vehicle stability. However, as a key component with concentrated weight, the bracket supports other devices and is connected to the left and right longitudinal beams. Without weight reduction treatment, it will significantly increase the overall vehicle weight and is not conducive to the current trend of vehicle lightweighting. Therefore, a multi-functional lightweight bracket is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multifunctional lightweight bracket, which aims to improve the problem that the bracket in the prior art has not undergone weight reduction treatment, which significantly increases the weight of the whole vehicle and is not conducive to the current trend of lightweight development of the whole vehicle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multifunctional lightweight bracket includes a bracket body with a cavity inside. A reinforcing plate is fixedly connected inside the cavity. The side of the bracket body is provided with mounting hole one, mounting hole two, and mounting hole three. Lightweight components are installed inside the bracket body.

[0011] As a further description of the above technical solution:

[0013] As a further description of the above technical solution:

[0014] The lightweight component includes a honeycomb core layer, a foam core layer, and a microgrid layer. The honeycomb core layer, the foam core layer, and the microgrid layer are all fixedly connected inside the support body. The honeycomb core layer is honeycomb-shaped, the foam core layer is foam-shaped, and the microgrid layer is grid-shaped.

[0016] Mounting hole one, mounting hole two, and mounting hole three are all boss structures with topology-optimized hollowing treatment in the middle.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, a cavity is opened in the main body of the support and the reinforcing plates are reasonably arranged, which effectively removes redundant materials in non-stressed areas, significantly reduces the overall weight, and the reinforcing plates construct a continuous stress transmission path along the stress direction, which improves local and overall stiffness and bending strength, optimizes fatigue life and prevents stress concentration and local buckling.

[0019] 2. In this utility model, a sandwich structure is adopted with a double-panel support body and a honeycomb, foam and micro-grid core layer. The core layer bears the shear load and maintains the panel spacing, which greatly improves the section modulus and overall stiffness.

[0025] 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.

[0026] Example 1:

[0027] Reference Figures 1-3 This utility model provides an embodiment of a multifunctional lightweight support, including a support body 1. The support body 1 has a cavity 2 inside. The cavity 2 structure is set in the area where the load is not significant, which can significantly reduce the weight while maintaining local stiffness. A reinforcing plate 3 is fixedly connected inside the cavity 2. The reinforcing plate 3 is reasonably arranged to improve the overall torsional stiffness and allow the wall thickness to be further optimized to the minimum safe value. The side of the support body 1 is provided with mounting holes 1 4, 2 5 and 3 6. Other components are connected to the support body 1 through mounting holes 1 4, 2 5 and 3 6. Lightweight components are installed inside the support body 1.

[0028] Reference Figures 1-3 The lightweight component includes a honeycomb core layer 101, which is fixedly connected to the inside of the support body 1. The honeycomb core layer 101 has a honeycomb shape and a two-dimensional hexagonal honeycomb structure. It is combined with the panel of the support body 1 by hot pressing or bonding process, which can provide excellent shear strength and damping.

[0029] Reference Figures 1-3 Mounting holes 1 (4), 2 (5), and 3 (6) are all boss structures with topology-optimized hollowing in the middle. The topology-optimized hollowing process significantly reduces weight, optimizes stiffness and strength, and homogenizes stress distribution.

[0030] Example 2:

[0031] Reference Figure 3 In contrast to the above embodiments, this utility model also provides an embodiment in which the lightweight component includes a foam core layer 102, which is fixedly connected to the inside of the support body 1. The foam core layer 102 is foam-shaped and is filled in the local interlayer, which has strong adaptability to complex geometry and effectively disperses stress.

[0032] Example 3:

[0033] Reference Figure 3In contrast to the above embodiments, this utility model also provides an embodiment in which the lightweight component includes a microgrid layer 103, which is fixedly connected to the inside of the support body 1. The microgrid layer 103 is grid-shaped and can be locally oriented for optimization, balancing energy absorption and stiffness, and achieving local reinforcement.

[0034] Example 4:

[0035] Reference Figure 3 In contrast to the above embodiments, this utility model also provides an embodiment in which the lightweight component includes a honeycomb core layer 101, a foam core layer 102, and a microgrid layer 103. The honeycomb core layer 101, the foam core layer 102, and the microgrid layer 103 are all fixedly connected inside the support body 1. The honeycomb core layer 101 is honeycomb-shaped, the foam core layer 102 is foam-shaped, and the microgrid layer 103 is grid-shaped. Through the coordinated work of the three core layers and the support body 1, the structural weight is significantly reduced while ensuring strength and fatigue performance, thus achieving lightweight treatment.

[0036] Working principle: A cavity 2 is opened in the main body 1 of the support to remove redundant materials in the area and reduce weight. At the same time, a reinforcing plate 3 is arranged in the main stress-bearing parts to build a stress transmission path from the root to the plate, thereby improving local and overall stiffness and bending strength. The reinforcing plate 3 is set along the direction of force and is connected to the plate through rounded corners to avoid stress concentration and local buckling. With the synergistic effect of the cavity 3 and the reinforcing plate 3, the support plate is made lightweight while ensuring strength and stiffness, and fatigue life is optimized.

[0037] The support body 1 employs a sandwich structure of double-panel panels and core layers. The upper and lower support body 1 panels bear bending loads, while the middle honeycomb core layer 101, foam core layer 102, and microgrid layer 103 withstand shear and maintain panel spacing, significantly improving the section modulus and achieving high stiffness and lightweight. The honeycomb core layer 101 provides excellent shear strength and damping with hexagonal units, the foam core layer 102 adapts to complex geometry and disperses stress, and the microgrid layer 103 achieves local reinforcement through directional microstructures. The three core layers work together with the support body 1 panels to significantly reduce the structure's self-weight while ensuring strength and fatigue performance.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
