Description

Technical Field

[0001] This utility model relates to the field of automotive underbody protection technology, specifically an automotive underbody protection plate that is easy to disassemble and repair. Background Technology

[0002] Engine skid plates are engine protection devices custom-designed for various vehicle models. Their primary purpose is to prevent mud from covering the engine, and secondly, to prevent engine damage caused by impacts from uneven road surfaces during driving.

[0003] Currently, many OEMs use snap-fit ​​or screw-mounted structures for the disassembly and repair of underbody protection plates. Snap-fit ​​installations are complex and difficult to assemble. To address this issue, patent document CN209795379U discloses a car underbody protection plate that facilitates disassembly and repair. This plate uses a cylinder mounted at one end of the repair opening. A second spring in the cylinder compresses a limiting rod inserted into a limiting hole at one end of the cover plate, thus fixing the cover plate in the repair opening. During disassembly and repair, pulling the limiting rod disengages it from the limiting hole, allowing the cover plate to detach from the repair opening. This changes the traditional screw-mounted method, making disassembly much easier. However, the above technical solution still needs improvement in the disassembly process. Therefore, this utility model designs a car underbody protection plate that facilitates disassembly and repair to solve the aforementioned problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a car underbody protection plate that is easy to disassemble and repair, including a mounting bracket 1 installed on the bottom of the car. During assembly, the mounting bracket 1 is welded or fixed to the bottom of the car by screws. The mounting bracket 1 has two symmetrically arranged locking grooves 2 inside. A protective plate 3 is snapped between the opposite surfaces of the two locking grooves 2. The material of the protective plate 3 can be customized according to actual needs. The material of the protective plate 3 is preferably resin or carbon steel.

[0023] The surface of the protective plate 3 is provided with several inspection holes 15. Each inspection hole 15 is fitted with an inspection cover plate on its inner wall. The purpose of the inspection holes 15 is to perform inspection and maintenance work on the bottom components of the vehicle.

[0024] The protective plate 3 is equipped with an elastic locking mechanism that engages with two locking slots 2, and a positioning component is also installed inside the protective plate 3.

[0025] The elastic locking mechanism includes a rotating shaft 4 located at the center of the protective plate 3 and two locking frames 5 arranged symmetrically around the rotating shaft 4. The locking frames 5 are L-shaped structures. The circumferential side of the rotating shaft 4 is rotatably connected to the protective plate 3. A handle 12 is fixedly installed at one end of the rotating shaft 4. A cross hole is fixedly opened at the center of the handle 12.

[0026] A drive plate 6 is fixedly installed on the circumferential side of the rotating shaft 4. Two symmetrically arranged transmission guide grooves 7 are opened on the surface of the drive plate 6. The inner walls of the two transmission guide grooves 7 are slidably connected to the two lock frames 5 respectively. A set of guide rods 8 are fixedly installed on the surface of each of the two lock frames 5. The circumferential side of the guide rods 8 is slidably connected to the protective plate 3. Lock plates 9 are fixedly installed on the surface of each of the two lock frames 5 through the guide rods 8. The circumferential side of the two lock plates 9 respectively cooperate with the two lock grooves 2.

[0027] The two locking plates 9 are slidably connected to the protective plate 3. The protective plate 3 has two symmetrically arranged storage slots that cooperate with the locking plates 9. The two locking plates 9 can be stored in the storage slots. A set of stop teeth 11 arranged in a linear array is fixedly connected to the end face of the locking plates 9. A set of stop grooves that cooperate with the stop teeth 11 are opened on the inner wall of the two locking grooves 2.

[0028] A tensile spring 10 is fitted around the periphery of the guide rod 8, and the two ends of the tensile spring 10 are fixedly connected to the protective plate 3 and the lock frame 5, respectively.

[0029] Among them, two symmetrically arranged limiting blocks 13 are fixedly installed on the inner wall of the protective plate 3. The peripheral side surfaces of the two limiting blocks 13 respectively cooperate with the two locking frames 5. The two locking frames 5 are arranged between the two limiting blocks 13. The function of the limiting blocks 13 is to limit the movable position of the two locking frames 5 respectively.

[0030] The positioning component includes a set of embedded posts 16 regularly distributed on the top surface of the protective plate 3. Each embedded post 16 has a tube 14 snapped into its peripheral side. The peripheral side of the embedded post 16 is fixedly connected to the protective plate 3, and the top end of the tube 14 is fixedly connected to the mounting bracket 1.

[0031] Working principle: During assembly, the mounting bracket 1 is welded or fixed to the bottom of the car with screws. When the protective plate 3 needs to be assembled onto the mounting bracket 1, the user rotates the handle 12. After the handle 12 is rotated, both locking brackets 5 move away from the limit plate. After the two locking brackets 5 move, the two locking plates 9 are finally stored in the two storage slots respectively. After the two locking plates 9 are stored, they are then separated from the mounting bracket 1. At this time, the protective plate 3 can be quickly removed from the bottom of the car. During assembly, the operation is reversed to quickly assemble the protective plate 3 onto the mounting bracket 1. After the protective plate 3 is assembled onto the mounting bracket 1, due to the action of the tension spring 10, the two locking plates 9 can be pressed tightly into the two locking slots 2 respectively.
