Description

Technical Field

[0001] This utility model relates to the field of SS technology, and in particular to a lightweight EVA carbon fiber sheet. Background Technology

[0002] EVA carbon fiber laminate is a composite material that combines carbon fiber sheets with EVA laminate, and it is widely used in the new energy vehicle industry.

[0003] However, in existing technologies, EVA carbon fiber sheets are limited by structural design, with a single connection method between the support frame and the sheet body, lacking an efficient force transmission path, resulting in insufficient overall structural strength. Under large loads, they are prone to deformation or even breakage. At the same time, the material stacking method is not optimized, and excess material increases the overall weight, making it difficult to meet the requirements for lightweighting. In addition, under load, stress is concentrated at connection nodes or weak parts, such as the corners of the sheet body and the junctions of components. The lack of an effective structure to disperse stress leads to premature local damage and uneven overall stress distribution, further reducing the load-bearing performance. Utility Model Content

[0004] The purpose of this invention is to solve the problems of insufficient structural strength, large weight, and uneven stress distribution in the existing technology, which make it difficult to meet the requirements of modern lightweight and high load-bearing performance, and proposes a lightweight EVA carbon fiber sheet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight EVA carbon fiber sheet, comprising a support frame, a horizontal plate and an arched plate, one end of the support frame being fixedly connected to one end of the horizontal plate, a first connecting rod being fixedly installed at the junction of the support frame and the horizontal plate, one end of the arched plate being fixedly connected at the junction of the support frame and the horizontal plate, and the arched plate being located above the support frame.

[0006] Preferably, a reinforcing plate is fixedly connected between the arched slab and the supporting frame, and the reinforcing plate has a bent structure.

[0007] Preferably, the top of the support frame is provided with a bent portion, which is fixedly connected to both the arched plate and the reinforcing plate.

[0008] Preferably, a recess is provided at the junction of the reinforcing plate and the bending part, and a second connecting rod is fixedly installed at the junction of the reinforcing plate and the supporting frame, and the second connecting rod is fixedly connected to the first connecting rod.

[0009] Preferably, a rectangular through hole is formed at the junction of the arched plate, the reinforcing plate, and the bend.

[0010] Preferably, positioning holes are provided at the corners of the horizontal plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the EVA carbon fiber sheet is composed of a support frame, a horizontal plate, an arched plate, and a reinforcing plate with a bent structure. When subjected to external forces, the arched plate disperses and transmits the force, and the arched structure can effectively decompose the loads in the vertical and horizontal directions. The reinforcing plate connects the arched plate and the support frame, and the bent structure increases the stress area and structural stability, so that all components work together to resist external forces.

[0013] 2. In this utility model, the recessed part at the junction of the reinforcing plate and the bending part can accommodate the stress generated by the deformation of the component and prevent stress concentration. Furthermore, the presence of the second connecting rod further improves the connection stability between the reinforcing plate and the support frame. The rectangular through hole formed by the arched plate, the reinforcing plate and the bending part reduces weight without affecting the overall structural strength. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1: As Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a lightweight EVA carbon fiber sheet, including a support frame 1, a horizontal plate 2, and an arched plate 3. One end of the support frame 1 is fixedly connected to one end of the horizontal plate 2. A first connecting rod 6 is fixedly installed at the junction of the support frame 1 and the horizontal plate 2. One end of the arched plate 3 is fixedly connected at the junction of the support frame 1 and the horizontal plate 2. The arched plate 3 is located above the support frame 1. A reinforcing plate 4 is fixedly connected between the arched plate 3 and the support frame 1. The reinforcing plate 4 is a bent knot.

[0021] The specific setup and function of this embodiment will be described in detail below. The entire EVA carbon fiber sheet consists of a support frame 1, a horizontal plate 2, an arched plate 3, and a reinforcing plate 4 with a bent structure. All structures are made of EVA carbon fiber sheet. One end of the support frame 1 is fixed to the horizontal plate 2 to form a basic support structure. The first connecting rod 6 at the junction improves the structural strength of the connection. One end of the arched plate 3 is connected to the junction of the two and is located above the support frame 1. When subjected to external forces, the arched plate 3 disperses and transmits the force. The arched structure can effectively decompose the vertical and horizontal directions. The reinforcing plate 4 connects the arched plate 3 to the supporting frame 1. The bent structure increases the load-bearing area and structural stability, enabling all components to work together to resist external forces. Through the connection of each component and the setting of the reinforcing plate 4, the overall structural strength and stability are enhanced, the load-bearing capacity is improved, and it can withstand large external forces without easily deforming or being damaged. The design of the arched plate 3 optimizes the force transmission path and reduces stress concentration. The bent structure of the reinforcing plate 4 further strengthens the connection parts, ensuring the reliability of the structure under complex stress conditions. It is suitable for various scenarios that require stable support and load bearing.

[0022] Example 2: Figure 1 , Figure 2 and Figure 3 As shown, the top of the support frame 1 is provided with a bending part 8, which is fixedly connected to the arched plate 3 and the reinforcing plate 4. A recessed part 7 is provided at the junction of the reinforcing plate 4 and the bending part 8. A second connecting rod 9 is fixedly installed at the junction of the reinforcing plate 4 and the support frame 1. The second connecting rod 9 is fixedly connected to the first connecting rod 6. A rectangular through hole 10 is formed at the junction of the arched plate 3, the reinforcing plate 4 and the bending part 8. A positioning hole 5 is provided at the corner of the horizontal plate 2.

[0023] The overall effect of this embodiment is that the bent portion 8 at the top of the support frame 1 is fixed to the arched plate 3 and the reinforcing plate 4, forming a stable connection node. The bent portion 8 changes the direction of force transmission and disperses the force. The recessed portion 7 at the junction of the reinforcing plate 4 and the bent portion 8 can accommodate the stress generated by the deformation of the component and prevent stress concentration. Furthermore, the presence of the second connecting rod 9 further enhances the connection stability between the reinforcing plate 4 and the support frame 1. The rectangular through hole 10 formed by the arched plate 3, the reinforcing plate 4, and the bent portion 8 reduces weight without affecting the overall structural strength. The positioning hole 5 at the corner of the horizontal plate 2 facilitates precise installation and positioning. All components work together to enhance structural stability and strength, effectively disperse stress, and improve load-bearing capacity. The design of the recessed portion 7 and the rectangular through hole 10 achieves lightweighting while ensuring structural performance. The positioning hole 5 facilitates installation, improves assembly efficiency and accuracy, and is suitable for various scenarios with requirements for structural strength and installation accuracy.

[0024] The usage and working principle of this device are as follows: When bearing external forces, the horizontal plate 2 and the supporting frame 1 form a basic support. The arched plate 3 is connected at the junction of the two. The arched structure decomposes the vertical and horizontal loads and disperses the force. The bending structure of the reinforcing plate 4 increases the load-bearing area and works with the arched plate 3 and the supporting frame 1 to resist external forces. The bending part 8 at the top of the supporting frame 1 changes the direction of force transmission and forms a stable node with the arched plate 3 and the reinforcing plate 4. The recessed part 7 at the junction of the reinforcing plate 4 and the bending part 8 accommodates deformation stress and prevents stress concentration. The rectangular through hole 10 formed by the arched plate 3, the reinforcing plate 4, and the bending part 8 reduces weight while ensuring strength. The positioning hole 5 at the corner of the horizontal plate 2 assists in precise installation and positioning. All components cooperate with each other to achieve efficient load bearing and stable support.
