Description

Technical Field

[0001] This utility model belongs to the field of automotive protection technology, and in particular relates to a PET continuous fiber automotive underbody protection plate. Background Technology

[0002] During driving, the bottom of a car is constantly exposed to the elements, facing a complex and harsh working environment. Gravel and sharp objects flying from the road can directly impact the bottom of the vehicle, causing damage to chassis mechanical components such as the engine oil pan, transmission housing, and suspension components. This can affect the normal operation of the vehicle and even create safety hazards. To address these challenges, underbody protection plates have emerged, bearing the important responsibility of protecting the mechanical components and chassis structure of the car's bottom and resisting external environmental erosion and damage.

[0003] Most existing automotive underbody protection plates are one-piece designs. When repairing a vehicle, it is often necessary to disassemble the entire underbody protection plate and repair the vehicle, which greatly increases the labor intensity of workers and reduces the efficiency of vehicle repair. Therefore, a PET continuous fiber automotive underbody protection plate is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a PET continuous fiber automotive underbody protection plate to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A PET continuous fiber automotive underbody protection plate includes an underbody protection plate body, auxiliary plates at both ends of the underbody protection plate body, first slots at both ends of the underbody protection plate body, a retaining plate at one end of the auxiliary plate, U-shaped rods at the bottom of both ends of the underbody protection plate body, a reinforcing rod at the bottom of one end of the auxiliary plate, the U-shaped rods and the reinforcing rods being connected by fixing bolts, and louvers at the other end of the auxiliary plate.

[0007] In a further technical solution, the number of auxiliary plates is two, and one end of each auxiliary plate is connected to the first slot via a card plate.

[0008] In a further technical solution, a limiting groove is provided on the top of both the main body of the bottom guard plate and the auxiliary plate, and a hydrophobic filter screen is connected to the bottom of the limiting groove.

[0009] In a further technical solution, ventilation slots are provided inside both the main body of the bottom protective plate and the auxiliary plate, and the ventilation slots are arranged in a honeycomb pattern.

[0010] In a further technical solution, a connecting plate is provided on the outer bottom of the main body of the bottom guard plate and the auxiliary plate, and the connecting plate is provided with a threaded groove and a second slot.

[0011] In a further technical solution, both the bottom of the main body and the auxiliary plate of the bottom guard plate are provided with buffer pads, and both the main body and the auxiliary plate of the bottom guard plate are made of PET continuous fiber material.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model achieves a modular design by using auxiliary plates at both ends of the main body of the underbody protection plate and connecting them with a locking plate and a first locking groove, a U-shaped rod and a reinforcing rod, and fixing bolts. Compared with the traditional one-piece underbody protection plate, maintenance does not require disassembling the whole plate; only the corresponding auxiliary plates need to be removed. This significantly reduces the labor intensity of workers, improves vehicle maintenance efficiency, and reduces maintenance time and costs. Furthermore, the connection structure between the reinforcing rod and the U-shaped rod enhances the overall structural stability and improves the deformation resistance of the underbody protection plate.

[0014] In this invention, the louvers on the other end of the auxiliary plate, together with the internal honeycomb-shaped ventilation slots, promote air circulation and help dissipate heat from chassis components such as the engine, preventing performance degradation or malfunction due to overheating. The limiting slot and hydrophobic filter at the top prevent water and dust from entering the vehicle chassis after the louvers are opened, thus affecting vehicle use. The hydrophobic filter also provides good ventilation, further improving the vehicle's heat dissipation. The threaded groove and second locking groove on the connecting plate facilitate precise connection and positioning with the vehicle chassis, ensuring stable and convenient installation, while also providing an interface for possible future functional expansion or component additions.

[0015] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description
