Description

Technical Field

[0001] The present invention relates to the technical field of forklift truck frames, and in particular to a high-strength lightweight composite forklift truck frame. Background Art

[0002] A forklift truck is an industrial handling vehicle, referring to various wheeled handling vehicles for loading, unloading, stacking, and short-distance transportation of palletized goods in pieces. It is widely used in various national economic sectors such as stations, ports, airports, factories, warehouses, etc., and is an efficient device for mechanized loading, unloading, stacking, and short-distance transportation.

[0003] According to the above, currently, the frames of forklift trucks mostly adopt structures made of all-metal materials. Although they have high strength, they also bring a significant increase in weight, which is not conducive to the popularization and application of small-tonnage electric forklift trucks. Therefore, in view of the above defects, it is necessary to design a high-strength lightweight composite forklift truck frame. Summary of the Invention

The first carbon fiber sleeve is fixedly arranged on the outside of the I-shaped core frame, and the first carbon fiber sleeve and the I-shaped core frame are connected by an adhesive. The second carbon fiber sleeve is fixedly arranged on the outside of the first carbon fiber sleeve, and the second carbon fiber sleeve and the first carbon fiber sleeve are connected by an adhesive. The high-temperature resistant sleeve is fixedly arranged on the outside of the second carbon fiber sleeve, and the high-temperature resistant sleeve and the second carbon fiber sleeve are connected by an adhesive. The wire harness holes are located on the left and right sides inside the high-temperature resistant sleeve. The wire harness holes are circular through holes. The protective outer sleeve is fixedly arranged on the outside of the high-temperature resistant sleeve, and the protective outer sleeve and the high-temperature resistant sleeve are connected by a snap-fit connection.

[0006] Furthermore, both the I-shaped core frame and the protective outer sleeve are made of metal materials.

[0007] Furthermore, the fibers of the first carbon fiber sleeve are longitudinally distributed.

[0008] Furthermore, the fibers of the second carbon fiber sleeve are transversely distributed.

[0009] Furthermore, the high-temperature resistant sleeve is made of aerogel material.

[0010] Furthermore, an anti-static rubber tube is also fixedly arranged inside the wire harness hole, and the anti-static rubber tube and the wire harness hole are connected by an adhesive.

[0011] Further, positioning grooves are provided on both the left and right sides of the first carbon fiber sleeve, the second carbon fiber sleeve, the high-temperature resistant sleeve, and the protective outer sleeve, and the positioning grooves are rectangular grooves.

[0012] Compared with the prior art, the high-strength lightweight forklift composite frame has the following advantages;

[0013] First of all, the present invention adopts a composite method of a variety of new materials, which well solves the defect that the traditional single use of metal materials, although ensuring strength, also leads to a substantial increase in weight.

[0014] Secondly, the present invention adopts a cooperation method of the first carbon fiber sleeve and the second carbon fiber sleeve, which further enhances the tensile resistance and impact resistance effects in different directions.

[0015] Finally, the high-temperature resistant sleeve built in the present invention not only achieves super high-temperature resistance and fire prevention, but also can enhance the frame strength, greatly reduce the increase in weight, and further achieve the purpose of lightweight.

[0021] The following specific embodiments will be further described in conjunction with the above drawings. Specific Embodiments

[0022] In the following text, a variety of specific details are elaborated in order to provide a thorough understanding of the concepts underlying the described embodiments. However, it is obvious to those skilled in the art that the described embodiments can be practiced without some or all of these specific details. In other cases, well-known processing steps are not specifically described.

[0023] Such as Figure 1 , Figure 2 , Figure 3 ,Figure 4 As shown in the figure, a high-strength lightweight forklift composite frame includes an I-shaped core frame 1, a first carbon fiber sleeve 2, a second carbon fiber sleeve 3, a high-temperature resistant sleeve 4, a wire harness hole 5, a protective outer sleeve 6, an anti-static rubber hose 501, and a positioning groove 601;

[0024] In one embodiment, the I-shaped core frame 1, as a metal component, provides necessary strength support. While achieving the basic strength, it also facilitates the first carbon fiber sleeve 2 to wrap and cover it;

[0025] In one embodiment, the first carbon fiber sleeve 2 and the second carbon fiber sleeve 3 are sequentially wrapped and fixed on the outside of the I-shaped core frame 1. By leveraging the advantages of high strength and low weight of the carbon fiber material, the overall strength and lightweight structure of the frame can be maximally improved. At the same time, since the fibers of the first carbon fiber sleeve 2 are longitudinally distributed and the fibers of the second carbon fiber sleeve 3 are transversely distributed, they can jointly generate anti-tensile and anti-impact effects in two directions, further enhancing the overall stability of the frame;

[0026] In one embodiment, the high-temperature resistant sleeve 4 is made of aerogel material. By leveraging the maximum high-temperature resistance effect of 1400°C of aerogel, as well as its density lower than air and super high hardness, it can achieve super high-temperature resistance and fire protection while also enhancing the frame strength, significantly reducing the increase in weight, and further achieving the purpose of lightweight;

[0027] In one embodiment, the wire harness holes 5 are located on both sides inside the high-temperature resistant sleeve 4, and the anti-static rubber hoses 501 are fixed on the inner walls, facilitating the placement of the power wire harness on the forklift. Since it is located inside the high-temperature resistant sleeve 4 and the anti-static rubber hose 501, it has high fire protection and insulation and anti-static effects;

[0028] In one embodiment, the protective outer sleeve 6 is made of metal material and is tightly sleeved outside the high-temperature resistant sleeve 4, which can wrap and protect the high-temperature resistant sleeve 4, provide necessary protection against puncture, scratch, and impact, and enhance the overall strength of the frame;

[0029] In one embodiment, the positioning groove 601 can facilitate the mutual fitting of the I-shaped core frame 1, the first carbon fiber sleeve 2, the second carbon fiber sleeve 3, the high-temperature resistant sleeve 4, and the protective outer sleeve 6, facilitating positioning and limiting, and effectively avoiding problems such as loosening and slipping;

[0030] Specifically, this vehicle frame can be used as the non-primary weighing frame of a forklift. Firstly, the I-shaped core frame 1 and the protective outer sleeve 6 serve as the basic metal support and anti-impact structure, providing good strength ductility and puncture resistance of the metal, and also providing the necessary basic strength. Secondly, in combination with the high tensile resistance, impact resistance and light weight of the first carbon fiber sleeve 2 and the second carbon fiber sleeve 3, while maximizing the overall strength of the vehicle frame, it further reduces the overall weight of the vehicle frame, achieving a lightweight structure. At the same time, since the high-temperature resistant sleeve 4 and the protective outer sleeve 6 are also provided on the outside, the defect of being easily punctured is effectively avoided. Finally, with the assistance of the high-temperature resistant sleeve 4 made of aerogel material, it can not only enhance the strength of the vehicle frame and greatly reduce the increase in weight, but also achieve super high-temperature resistance and fire prevention effects, expanding the use effect and application scenario of the vehicle frame.

[0031] The present invention is not limited to the above specific embodiments. Those of ordinary skill in the art starting from the above concepts and making various transformations without creative labor fall within the protection scope of the present invention.
