Description

Technical Field

[0001] The utility model relates to a buffer structure for an automobile engine cover. Background Art

[0002] A car's hood, also commonly known as the engine compartment cover or bonnet, is part of the vehicle's body structure, located above the engine compartment. Its primary functions include protecting the engine and surrounding wiring and components while ensuring adequate heat dissipation. Hood design often incorporates aerodynamic principles to reduce wind resistance, improve fuel economy, and enhance vehicle stability. There are various ways to open the hood, including the hand-operated method: a more traditional method, common in earlier models. The driver manually lifts the hood upward and then secures it in place. The lever-operated method has become increasingly popular with advancements in vehicle design. The driver unlocks and raises the hood by pulling a lever from inside the vehicle, making it more convenient. Hydraulic hood opening: Some high-end models utilize a hydraulic system to automatically raise and lower the hood, making it both easy to operate and enhancing the vehicle's luxurious feel.

[0003] The car hood is a component used to protect the engine compartment. The existing hand-held hood needs to be closed by using the weight of the hood to ensure that the hood is locked in place. However, it is difficult to control the closing force when closing. If the force is too light, it cannot be locked. If the force is too strong, it will cause loud noise. In serious cases, it is easy to cause damage to the hood, especially the locking part is subject to greater impact force. Long-term use may easily cause the locking position to loosen. During driving, the hood may cause vibration and generate loud noise, affecting the performance of the hood. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The present utility model will be further described below by way of examples, but the present utility model is not limited to the scope of the described examples.

[0026] Such as Figure 1-3As shown in the figure, the buffer structure for an automobile engine hood includes:

[0027] The hood 2 is rotatably connected to the vehicle body 1. The edge of the hood 2 is fixedly connected to the inner lining plate 4 through an elastic plate 3. The bottom of the inner lining plate 4 is fixedly connected to a bearing plate 6, and the bearing plate 6 is correspondingly arranged above a sunken groove 14 opened in the vehicle body 1. A sunken groove 14 is opened in the middle of the front end of the vehicle body 1. A hook 15 is rotatably connected inside the sunken groove 14. The hook 15 is correspondingly arranged below a catch 7, and the catch 7 is fixedly connected to the bearing plate 6. Buffer mechanisms corresponding to the bearing plate 6 are opened on the vehicle body 1 on both sides of the sunken groove 14.

[0028] In this technical solution, the hood 2 is of an arc structure. The bottom edge of the hood 2 is fixedly connected to an arc-shaped elastic plate 3, and the elastic plate 3 is fixedly connected to the four weeks of the inner lining plate 4 respectively. When the edge of the hood 2 fits on the vehicle body 1, at this time, the bearing plate 6 pulls the elastic plate 3 and the hood 2 through the locking of the hook 15 and the catch 7, so that the elastic plate 3 is in an elastic deformation state when the hood 2 is closed to ensure the tightness after the hood 2 is closed.

[0029] In this technical solution, a pressure pad 5 is fixedly connected inside the hood 2. The pressure pad 5 is in contact with the top surface of the inner lining plate 4. When the hood 2 is closed, the bearing plate 6 contacts the buffer mechanism on the vehicle body 1. At this time, the bearing plate 6 drives the inner lining plate 4 to approach the hood 2, so that the inner lining plate 4 contacts the pressure pad 5 on the hood 2, playing a role of buffer protection.

[0030] In this technical solution, the inner lining plate 4 is of an arc structure and is located in the middle of the hood 2. One end of the bottom of the inner lining plate 4 is provided with a bearing plate 6, and the bottom surface of the bearing plate 6 contacts the vehicle body 1. The contact between the hood 2 and the buffer mechanism when the hood 2 is closed is realized by setting the bearing plate 6.

[0031] In this technical solution, a catch 7 with an L-shaped structure is provided in the middle of the bottom end of the bearing plate 6. A guide rod 19 is provided on one side of the catch 7. The bottom of the guide rod 19 is fixedly connected to the bearing plate 6. The bearing plate 6 drives the catch 7 to be clamped on the hook 15. At this time, the limit of the bearing plate 6 is realized. At this time, the elastic plate 3 is in a bent state, driving the hood 2 to closely adhere to the edge of the vehicle body 1.

[0032] In this technical solution, the buffer mechanism includes a connecting plate 10 which is fitted into a groove 8 formed in the vehicle body 1. The bottom of the connecting plate 10 is connected to the vehicle body 1 through a buffer spring 9. A buffer pad 11 is fixedly connected to the top of the connecting plate 10. The buffer pad 11 is correspondingly arranged below the bearing plate 6. A gap for air flow to enter is formed between the connecting plate 10 and the groove 8. When the bearing plate 6 contacts the buffer mechanism, the buffer pad 11 and the connecting plate 10 move downward, thus playing a buffering role. When the vehicle hood 2 is opened, when the buffer spring 9 restores and pushes the connecting plate 10 upward, at this time, the peripheral edge 12 and the connecting plate 10 are separated, enabling external gas to enter the groove 8.

[0033] In this technical solution, a peripheral edge 12 is fixedly connected to the bottom edge of the connecting plate 10. The peripheral edge 12 is made of deformable rubber material and is fitted and connected to the inner wall of the groove 8. An air hole 13 extending to the outside of the vehicle body 1 is formed in the groove 8 below the peripheral edge 12. When the vehicle hood 2 is closed, the downward movement of the connecting plate 10 drives the peripheral edge 12 to move synchronously, making the peripheral edge 12 fit with the edge of the connecting plate 10. At this time, the gas inside the groove 8 is compressed, and the gas inside the groove 8 is discharged from the air hole 13, which can play a protective role for the vehicle hood 2 by using the air pressure buffering function.

[0034] In this technical solution, a sunk groove 14 is formed in the middle of the vehicle body 1. The sunk groove 14 is located between two grooves 8 formed in the vehicle body 1. A hook 15 is rotatably connected to the bottom of the sunk groove 14. The two sides of the top of the hook 15 are respectively fixedly connected to a handle 17 and a limiting rod 18. The handle 17 is in transmission connection with a lock rod in the cab. The sunk groove 14 is used for the installation of the hook 15 and cooperates with the hook 7 to realize the locking of the vehicle hood 2.

[0035] In this technical solution, the cross-section of the hook 15 is a U-shaped structure. Both sides of the hook 15 are connected to the inner wall of the sunk groove 14 through a return spring 16. The hook 15 is internally clamped with the hook 7. When the vehicle hood 2 is closed, it drives the hook 7 to contact the hook 15, causing the hook 15 to rotate to one side and then realizing mutual clamping. When separating, only need to pull the lock rod from the driver's seat, drive the handle 17 to move through the transmission structure, and then realize the unlocking of the vehicle hood 2.

[0036] In the present technical solution, two counterbores 23 are provided at the top of the vehicle body 1. Both of the two counterbores 23 are located between the sunk groove 14 and the groove 8. The inside of the counterbore 23 is connected to a movable plate 21 through a connecting spring 20. The movable plate 21 is fitted and slidably engaged with the inside of the counterbore 23. And a channel 22 communicating with the groove 8 is provided at the bottom of the counterbore 23. When the vehicle cover 2 is closed, the bearing plate 6 drives the guide rod 19 to insert into the inside of the counterbore 23. When the guide rod 19 contacts the movable plate 21, the connecting spring 20 is compressed, and the movable plate 21 squeezes the gas to make the gas enter the inside of the groove 8 from the channel 22. At this time, the air inside the groove 8 is compressed and discharged from the air hole 13, further improving the buffer protection performance.
