Technical Field

[0001] This invention relates to the field of reinforcing plate technology, and in particular to a reinforcing plate for the inner panel of an automobile luggage compartment cover and its processing technology. Background Technology

[0002] Electric vehicles are vehicles that use on-board power sources to drive their wheels with electric motors and meet all road traffic and safety regulations. The trunk lid of an electric vehicle needs to be reinforced during the production process. Therefore, it is necessary to use a reinforcing plate inside the trunk lid for reinforcement. The reinforced trunk lid increases local stiffness and strength, thereby improving the trunk lid's resistance to deformation, collision energy absorption effect, and structural stability.

[0003] The existing luggage compartment cover inner panel reinforcement plate is made of metal. Due to factors such as shape design or material thickness distribution, its overall resistance to deformation is weak. When subjected to external forces or dynamic loads, it is prone to deformation, affecting its functional realization and assembly stability. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a reinforcing plate for the inner panel of an automobile luggage compartment cover and its processing technology.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a reinforcing plate for the inner panel of a car luggage compartment cover, comprising a reinforcing plate body, wherein the reinforcing plate body comprises a first bottom plate and a second bottom plate, the first bottom plate and the second bottom plate are fixedly connected by a thin rod, and a reinforcing mechanism and a vertical mechanism are provided on the first bottom plate and the second bottom plate; The reinforcement mechanism includes a third and a fourth circular hole inside the first base plate, which are staggered and interconnected. The inner walls of the third and fourth circular holes are respectively provided with reinforcing ribs B and A, which are staggered. The mechanism also includes a first and a second circular hole inside the second base plate, which are staggered and interconnected. The inner walls of the first and second circular holes are respectively provided with reinforcing ribs D and C, which are staggered.

[0006] Preferably, a connecting hole is provided between the fourth circular hole and the first circular hole, and a connecting rib is provided on the inner wall of the connecting hole. The connecting rib is fixedly connected to the inner reinforcing rib A and reinforcing rib D respectively.

[0007] Preferably, the reinforcement mechanism further includes a reinforcement plate, which is fixedly connected to the first base plate and the second base plate respectively. The upper ends of the reinforcement plate, the first base plate and the second base plate are smoothly connected by a connecting arc surface A, and the lower ends of the reinforcement plate, the first base plate and the second base plate are smoothly connected by a connecting arc surface C. An arc-shaped notch is provided at the right end of the reinforcement plate.

[0008] Preferably, the reinforcing plate has multiple evenly arranged honeycomb grooves at both its upper and lower ends, and the top of the first and second base plates each has multiple rectangular holes.

[0009] Preferably, the vertical mechanism includes a third vertical plate fixedly connected between the first base plate and the second base plate. The third vertical plate has two mounting holes. A connecting arc plate A is fixedly connected to the right end of the third vertical plate. A fourth vertical plate is fixedly connected to the right end of the connecting arc plate A. A second inclined plate is fixedly connected to the right end of the fourth vertical plate. The connecting arc plate A, the fourth vertical plate, and the second inclined plate are all fixedly connected to the second base plate and are smoothly connected through the connecting arc surface B.

[0011] Preferably, the second, third, and fourth vertical plates are provided with multiple inner and outer grooves at their front and rear ends, respectively.

[0012] A processing method for a reinforcing plate for the inner panel of a car trunk lid includes the following steps: Step 1: First, the first base plate is reinforced by reinforcing ribs B and A in the reinforcement mechanism, and the second base plate is reinforced by reinforcing ribs C and D, thereby improving the overall strength of the reinforcing plate body and extending its service life. Step 2: The vertical mechanism ensures that the reinforcing plate is tightly fitted inside the car's trunk lid, facilitating subsequent installation.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the reinforcement mechanism, the strength of the reinforced plate body can be improved by the cooperation of the reinforcing ribs A, B, C, D and connecting ribs, thereby improving the overall resistance to deformation, and thus improving the load-bearing capacity and ensuring the stability of the assembly. In addition, the load-bearing capacity can be further improved by the honeycomb groove. 2. By using rectangular holes, the weight of the reinforcing plate can be reduced without affecting its strength, making it lighter and thus reducing manufacturing costs. 3.

Detailed Implementation

[0016] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0017] like Figures 1-8 The illustration shows a reinforcing plate for the inner panel of a car trunk lid, comprising a reinforcing plate body, which includes a first base plate 1 and a second base plate 2. The first base plate 1 and the second base plate 2 are fixedly connected by thin rods. The first base plate 1 and the second base plate 2 are provided with a reinforcing mechanism and a vertical mechanism. The reinforcing mechanism increases the strength of the reinforcing plate body, thus reducing deformation during electric vehicle operation. The reinforcing mechanism includes a third circular hole 30 and a fourth circular hole 31 formed inside the first base plate 1. The third circular hole 30 and the fourth circular hole 31 are staggered and interconnected. The wall is provided with reinforcing ribs B22 and A21 respectively, and the reinforcing ribs B22 and A21 are arranged alternately. It also includes a first circular hole 28 and a second circular hole 29 opened inside the second base plate 2. The first circular hole 28 and the second circular hole 29 are arranged alternately and connected to each other. The inner walls of the first circular hole 28 and the second circular hole 29 are provided with reinforcing ribs D26 and C25 respectively, and the reinforcing ribs D26 and C25 are arranged alternately. Multiple reinforcing ribs can increase the bending and torsional resistance of the component, improve the rigidity of the overall structure, make the component less prone to deformation when subjected to external forces, and ensure the normal operation accuracy of the equipment.

[0018] The reinforcing ribs B22 and A21 can be placed through the third and fourth circular holes 30 and 31, respectively. The staggered arrangement of the reinforcing ribs B22 and A21 can resist compressive forces from different directions. The reinforcing ribs D26 and C25 can be placed through the first and second circular holes 28 and 29, respectively. The staggered arrangement of the reinforcing ribs D26 and C25 can resist compressive forces from different directions, thereby protecting the reinforcing plate body.

[0019] A connecting hole 27 is connected between the fourth circular hole 31 and the first circular hole 28. A connecting rib 24 is provided on the inner wall of the connecting hole 27. The connecting rib 24 is fixedly connected to the inner reinforcing rib A21 and reinforcing rib D26 respectively. The connecting rib 24 can strengthen the connection between different parts of the component, improve the overall structural integrity, and enable each part to work together and jointly bear external forces.

[0020] The first circular hole 28 and the fourth circular hole 31 are connected by the connecting hole 27. Since the first circular hole 28 and the fourth circular hole 31 are connected to the second circular hole 29 and the third circular hole 30 respectively, they can be regarded as a whole. The reinforcing ribs B22, A21, D26 and C25 are connected into a whole by the connecting rib 24, thereby improving the overall strength, preventing deformation during use and extending the service life.

[0021] The reinforcement mechanism also includes a reinforcement plate 4, which is fixedly connected to the first base plate 1 and the second base plate 2. The upper ends of the reinforcement plate 4, the first base plate 1, and the second base plate 2 are smoothly connected by a connecting arc surface A5, and the lower ends of the reinforcement plate 4, the first base plate 1, and the second base plate 2 are smoothly connected by a connecting arc surface C20. An arc-shaped notch 17 is provided on the right end of the reinforcement plate 4. During the overall assembly of the equipment, the arc-shaped notch 17 can provide space to avoid interference with other adjacent components or structures. For example, when pipelines, cables, or other mechanical components need to pass through this area, the arc-shaped notch 17 can provide sufficient space to ensure that each component can be installed smoothly, improving assembly efficiency and accuracy.

[0022] The reinforcement plate 4 increases the contact area, making the installation more secure. The connecting arc surfaces A5 and C20 make the connection surface smoother, resulting in a tighter contact between the electric vehicle luggage compartment cover and the door, reducing gaps and ensuring a tight fit for improved installation.

[0023] The reinforcing plate 4 has multiple evenly arranged honeycomb grooves 3 at both the top and bottom ends. The top of the first base plate 1 and the second base plate 2 are each provided with multiple rectangular holes 6. The honeycomb structure of the honeycomb grooves 3 has a high strength-to-weight ratio. While ensuring the overall strength of the component, it can effectively reduce the weight of the component, reduce the overall load of the equipment, and improve energy utilization efficiency. When subjected to impact, the honeycomb grooves 3 can absorb and disperse energy through their own deformation, reduce the impact force on other internal structures of the component, and play a good buffering and protection role. Removing some material to form rectangular holes 6 can effectively reduce the weight of the component without affecting its main function, and at the same time save material costs.

[0024] The honeycomb grooves 3 not only reduce weight but also increase strength, reducing deformation during use. The rectangular holes 6 further reduce overall weight, making it lighter.

[0025] The vertical mechanism includes a third vertical plate 11 fixedly connected between the first base plate 1 and the second base plate 2. Two mounting holes 13 are provided on the third vertical plate 11. A connecting arc plate A14 is fixedly connected to the right end of the third vertical plate 11, and a fourth vertical plate 15 is fixedly connected to the right end of the connecting arc plate A14. A second inclined plate 32 is fixedly connected to the right end of the fourth vertical plate 15. The connecting arc plate A14, the fourth vertical plate 15, and the second inclined plate 32 are all fixedly connected to the second base plate 2 and smoothly connected via a connecting arc surface B16. The third vertical plate 11 not only increases the stability of the component in the corresponding direction but also prevents tipping or swaying, ensuring the stability of the component during operation and providing more mounting points for easy integration with other components. The connecting and fixing plates enhance the overall integrity of the system. The connecting arc plate A14 achieves a smooth transition between different components, reducing stress concentration and wear at the connection points, and improving the reliability and durability of the connection. Its arc surface helps improve the sealing performance of the connection points, preventing leakage of liquids, gases, etc., making it suitable for applications with high sealing requirements. The fourth vertical plate 15 provides additional support for critical parts of the components, enhancing local load-bearing capacity and preventing damage due to excessive force. Its vertical surface may act as a guide, ensuring that related components or objects move along a predetermined direction during movement, improving work accuracy. The inclined structure of the second inclined plate 32 can guide and disperse the force acting on its surface. When subjected to external pressure or impact, the inclined plate can decompose the force along the inclined plane into different directions, reducing the force intensity in a single direction, thereby enhancing the overall impact resistance and stability of the components. The design of the second inclined plate 32 helps to better utilize space and adapt to different installation environments and usage requirements. It can form a more compact layout with surrounding components, reducing space occupation. At the same time, the inclined plane can adapt to other components with specific shapes, ensuring proper fit and coordinated operation between components.

[0026] The reinforcing plate body is installed on the luggage compartment cover of the electric vehicle through the mounting hole 13. The fourth vertical plate 15 and the third vertical plate 11 are fixedly connected together by the connecting arc plate A14. The connecting arc plate A14, the fourth vertical plate 15, and the second inclined plate 32 are also fixedly connected together.

[0027] The left end of the third vertical plate 11 is fixedly connected to a connecting arc plate B19. The left end of the connecting arc plate B19 is fixedly connected to a second vertical plate 10. The left end of the second vertical plate 10 is fixedly connected to an arc plate 9. The front end of the arc plate 9 is fixedly connected to a first vertical plate 8. The front end of the first vertical plate 8 is fixedly connected to a first inclined plate 7. The second vertical plate 10, the arc plate 9, the first vertical plate 8, and the first inclined plate 7 are all fixedly connected to the first base plate 1 and smoothly connected by a connecting arc surface B16. The arc design of the connecting arc plate B19 can effectively alleviate the stress concentration phenomenon at the connection of different components. When the component is subjected to external force, the stress will be evenly distributed along the arc surface, avoiding the formation of excessive stress peaks in a local area, thereby enhancing the structural strength of the connection and reducing the risk of cracking or damage. It achieves a smooth connection transition between different components. This smooth connection method can reduce friction and wear of components during relative movement and extend the service life of the components. For example, when an object moves at the connection point, the curved surface can guide the object to pass smoothly, avoiding jamming or collision. The second vertical plate 10 can further enhance the overall structural strength of the component, especially by providing support in the vertical direction, preventing the component from bending or twisting under stress. It can be used to separate different functional areas, prevent mutual interference between internal components, and facilitate maintenance and management. The curved design of the arc plate 9 helps to disperse stress concentration and avoid excessive stress in local areas, thereby improving the fatigue resistance and service life of the component. It can better adapt to the shape or movement trajectory of surrounding objects, reduce interference and friction, and make the component work more smoothly. The first vertical plate 8 acts as a protective barrier, protecting the internal components from impacts, dust, moisture, etc. from external objects, improving the durability and reliability of the component, and providing installation positioning references for other related components to ensure the correct assembly and relative position accuracy between components. The first inclined plate 7 can provide additional structural support, enhancing the rigidity and stability of the entire component, making it less prone to deformation when subjected to external pressure or vibration.

[0028] By connecting the arc plate B19, the second vertical plate 10 and the third vertical plate 11 are fixed together, and the second vertical plate 10, the arc plate 9, the first vertical plate 8 and the first inclined plate 7 are fixed together to form a whole.

[0029] The second vertical plate 10, the third vertical plate 11, and the fourth vertical plate 15 have multiple inner grooves 12 and outer grooves 18 at their front and rear ends, respectively. The inner grooves 12 and outer grooves 18 not only reduce the overall weight but also facilitate airflow, thereby ensuring that the installation area is always dry.

[0030] A processing method for a reinforcing plate for the inner panel of a car trunk lid includes the following steps: Step 1: First, the first base plate 1 is reinforced by reinforcing ribs B22 and A21 in the reinforcement mechanism, and the second base plate 2 is reinforced by reinforcing ribs C25 and D26, thereby improving the overall strength of the reinforcing plate body and extending its service life. Step 2: The vertical mechanism ensures that the reinforcing plate is tightly fitted inside the car's trunk lid, facilitating subsequent installation.
