A type of automotive reinforcement plate

Abstract

This utility model belongs to the technical field of automotive reinforcement plates, and more particularly to an automotive reinforcement plate. This utility model includes an upper steel plate and a lower steel plate disposed at the bottom of the upper steel plate. Both the upper and lower steel plates have integrally connected connecting lugs on their sides, with positioning holes in the connecting lugs allowing bolts to pass through. A lower pressure frame plate presses longitudinally against the bolt head, with a rotating mechanism at one end and a locking mechanism at the other. The rotating mechanism is connected to the connecting lug of the lower steel plate, and the locking mechanism is connected to the connecting lug of the upper steel plate. This utility model, through the lower pressure frame plate in conjunction with the rotating and locking mechanisms, longitudinally presses the bolt head, axially restricting bolt movement. The limiting block in the locking mechanism continuously presses against the locking protrusion under the action of a spring, ensuring the lower pressure frame plate remains locked, effectively counteracting high-frequency vibrations during vehicle operation. The operation is simple and convenient, and assembly can be completed by a single person.

Description

Technical Field

[0001] This utility model relates to the field of automotive reinforcement plate technology, specifically an automotive reinforcement plate. Background Technology

[0002] As a core load-bearing and protective component of the vehicle body, automotive reinforcement plates are widely used in key parts such as doors, chassis, and frames. Their core function is to improve the local structural rigidity, deformation resistance, and impact resistance of the vehicle body, thereby ensuring driving safety. This is especially important as the automotive industry moves towards lightweighting and high reliability.

[0003] When conventional reinforcing plates are assembled to the vehicle body with bolts, the bolts are fixed only by the friction of the threads. The continuous vibration during vehicle operation can cause gaps to appear in the threaded pair, leading to loosening or even detachment of the bolts, causing the reinforcing plate to separate from the vehicle body and lose its reinforcing function.

[0004] Therefore, we propose an automotive reinforcement plate to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an automotive reinforcing plate that solves the problem mentioned in the background art: when conventional reinforcing plates are assembled to the vehicle body with bolts, the bolts rely solely on thread friction for fixation. Continuous vibrations during vehicle operation can cause gaps in the threaded pair, leading to bolt loosening or even detachment, causing the reinforcing plate to separate from the vehicle body and lose its reinforcing function.

[0029] Example

[0030] like Figure 1-5 As shown, an embodiment of the present invention provides an automotive reinforcing plate, including an upper steel plate 1 and a lower steel plate 2 disposed at the bottom of the upper steel plate 1. A glass fiber reinforced plastic 3 is assembled between the upper steel plate 1 and the lower steel plate 2, such that the surface of the upper steel plate 1 is integrally connected with an insert groove 7, and both ends of the glass fiber reinforced plastic 3 are provided with protrusions extending into the insert groove 7, so that the entire reinforcing plate presents a three-layer composite structure.

[0031] Furthermore, both the upper steel plate 1 and the lower steel plate 2 have integrated connecting ear plates 6 on their sides. The connecting ear plates 6 have positioning holes 8 that allow bolts to pass through. The connecting ear plates 6 on the side of the upper steel plate 1 have a downward-extending design, while the connecting ear plates 6 on the side of the lower steel plate 2 are flush with the side of the lower steel plate 2. After the three-layer composite structure is attached, the upper and lower sets of connecting ear plates 6 are attached longitudinally, and the openings of the positioning holes 8 are completely aligned longitudinally. After the bolts are inserted through the positioning holes 8, it can be assembled with a specific installation position, thus completing the positioning and assembly of the entire reinforcing plate.

[0032] The bolt head will remain on the connecting ear plate 6. In order to reduce the bolt retraction caused by vibration and improve the stability of the connection between the entire reinforcing plate and the installation point, a lower pressure frame plate 13 is set to press horizontally on the bolt head, so that the bottom of the lower pressure frame plate 13 is pressed tightly on the bolt head, and the bolt is given downward pressure. A rotating mechanism is provided at one end of the lower pressure frame plate 13 and a locking mechanism is provided at the other end. The rotating mechanism is connected to the connecting ear plate 6 of the lower steel plate 2, and the locking mechanism is connected to the connecting ear plate 6 of the upper steel plate 1. Through the combination of the locking mechanism and the rotating mechanism, the lower pressure frame plate 13 can be stably pressed on the bolt head.

[0033] In order to provide stability for the combination of the upper steel plate 1, the lower steel plate 2 and the glass fiber reinforced plastic 3, a steel plate side groove 5 is provided on the side of the upper steel plate 1, and a side pressure protrusion 4 is fixed on the side of the lower steel plate 2, which extends upward and can be inserted into the groove of the steel plate side groove 5. After the complete assembly, the top of the side pressure protrusion 4 is inserted into the groove of the steel plate side groove 5, which can improve the stability and strength of the connection of the entire reinforcing plate side.

[0034] The rotating mechanism includes an adjusting groove 9, an adjusting plate 10, a rotating shaft 11, and a connecting horizontal plate 12. The adjusting groove 9 is located on the side of the connecting ear plate 6. The adjusting plate 10 is rotatably connected to the groove of the adjusting groove 9. The rotating shaft 11 is rotatably connected to the top groove of the adjusting plate 10. The connecting horizontal plate 12 is fixed to the outer wall of the rotating shaft 11. One end of the lower pressure frame plate 13 is fixed to the connecting horizontal plate 12. The side of the connecting ear plate 6 of the upper steel plate 1 has a groove that matches the adjusting groove 9. A rotating shaft is provided between the adjusting plate 10 and the groove wall of the adjusting groove 9. By rotating the adjusting plate 10 to a vertical position and rotating the connecting horizontal plate 12 to a horizontal position, the lower pressure frame plate 13, which is fixedly connected to the front end of the connecting horizontal plate 12, can be pressed against the top of the bolt head. The lower pressure frame plate 13 can be locked in place by locking.

[0035] Meanwhile, the locking mechanism includes a column plate 14, a locking protrusion 15, a protrusion groove 16, and a limiting block 18. The column plate 14 is fixed to the top of the connecting ear plate 6, and the protrusion groove 16 is formed on the top of the column plate 14. The locking protrusion 15 is fixed to one end of the connecting horizontal plate 12, and the limiting block 18 presses against the top of the locking protrusion 15. The front end of the locking protrusion 15 is inserted into the groove of the protrusion groove 16, and a functional compartment plate 17 is fixed to the side of the column plate 14. The limiting block 18 is slidably connected to the side of the functional compartment plate 17. A detachable spring is provided between the end of the limiting pressure block 18 and the groove of the functional compartment plate 17. The top of the limiting pressure block 18 is provided with a top gripping rod 19 that allows the limiting pressure block 18 to move laterally. The side of the functional compartment plate 17 has a detachable end cap that is bolted on, and the top of the functional compartment plate 17 is also provided with a sliding groove that allows the top gripping rod 19 to move laterally. Driven by the elasticity of the spring, the limiting pressure block 18 is kept pressing on the locking protrusion 15, so that the locking protrusion 15 cannot be disengaged from the groove of the protrusion slot 16 in the use state.
