Description

Technical Field

[0001] The invention belongs to the technical field of vibration and noise control, and in particular relates to a foam structure for improving the sealing of holes in a vehicle triangular window cover. Background Art

[0002] Triangular windows are important parts of a car. They can increase the driver's field of vision. When driving, you need to see not only the front of the car, but also the traffic on the left and right. If there are no triangular windows on the front doors, the driver may not be able to see the traffic in that direction and the surrounding situation, which may easily lead to traffic accidents. Triangular windows on rear doors can increase the sightseeing area of the rear row, making the field of vision of the rear passengers wider. In addition, the triangle shape has the best stability. The triangular windows on the car can make the entire window more stable.

[0003] Foam is a material made of foamed plastic particles. It has a series of characteristics such as elasticity, light weight, fast pressure-sensitive fixation, easy use, easy bending, ultra-thin volume, and reliable performance.

[0004] With the rapid development of automotive technology, especially electric vehicles, speed limits are constantly increasing, and wind noise from high-speed driving is increasing. Triangular windows are a key wind noise control point. If the openings are not strictly sealed, the wind noise caused by leakage will pose a serious challenge to the quietness of the vehicle interior.

[0005] Traditional sealing simply adds foam or controls the installation method without further sealing the installation holes. When the vehicle is driving at high speed, leakage near the triangular window is still relatively serious. Summary of the Invention

[0006] The present invention provides a foam structure for improving the sealing of holes in a vehicle's triangular window cover, aiming to solve the problem that traditional sealing simply involves adding foam or controlling the installation method without further sealing the installation holes, resulting in severe leakage near the triangular window when the vehicle is traveling at high speed.

[0007] The present invention is achieved by providing a foam structure for improving the sealing of holes in a vehicle triangular window cover, comprising:

[0008] The foam body comprises a groove, and at least one mounting hole is formed on the bottom surface of the groove;

[0009] At least one circle of hole ribs is provided at the edge of the mounting hole for sealing the mounting hole;

[0010] The foam body has a flange, and the flange is provided with at least one circle of mounting surface ribs.

[0011] As a further solution of the present invention, a plurality of auxiliary ribs are connected between the sides of the mounting surface ribs.

[0012] Furthermore, the width of the hole rib is 1-2 mm.

[0013] Furthermore, the height of the hole rib is 1-3 mm.

[0014] Furthermore, the hole position convex ribs and the installation surface convex ribs are integrally formed with the foam body.

[0015] Furthermore, the hole ribs are wavy in shape. Experiments have shown that wavy hole ribs can effectively reduce airflow disturbance and reduce airflow noise.

[0016] Furthermore, the width of the convex rib on the mounting surface is 1-2 mm.

[0017] Furthermore, there are three convex ribs at the hole positions, each 0.5 mm apart.

[0018] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0019] The foam structure for improving the sealing of the holes in the vehicle triangular window cover provided by the present invention is provided with hole position ribs and installation surface ribs on the basis of the traditional foam structure. It is simple, convenient and effective. The hole position ribs are used to directly seal the area near the hole position, which can block most of the airflow; the installation surface ribs can block the very small amount of leaked airflow again; the overall foam can be compressed by installation to further block the airflow, which can effectively improve the leakage wind noise caused by poor hole sealing in the triangular window, and greatly improve the quietness in the vehicle.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0025] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] Traditional triangular window foam has no features near the installation holes, so airflow is more likely to leak from the foam surface near the holes when driving at high speeds;

[0027] The embodiment of the present invention provides a foam structure for improving the sealing of the hole of the vehicle triangular window 1 cover plate, such as Figure 1-Figure 3 Shown, including:

[0028] A foam body 5, wherein the foam body 5 has a groove, and at least one mounting hole 2 is formed on the bottom surface of the groove;

[0029] At least one circle of hole ribs 3 provided on the foam body 5 and outside the mounting hole 2 directly seals the area near the hole, thereby mostly blocking the airflow.

[0030] The width of the hole rib 3 is 1-2 mm. If it is too narrow, it may be insufficient in strength and fail to achieve the sealing effect of blocking the airflow. If it is too wide, it is unnecessary and will cause waste of materials.

[0031] In this embodiment, at least one circle of mounting surface ribs 4 is provided on the mounting surface flange of the foam body 5. The width of the mounting surface ribs 4 is 1-2 mm. The mounting surface ribs 4 can block the very small amount of leaked airflow again.

[0032] In a specific implementation, the hole position rib 3 and the mounting surface rib 4 can together form an encircling circle that seals the mounting hole 2. Specifically, in some positions, the hole position rib 3 and the mounting surface rib 4 can share a length, as long as they can enclose the mounting hole 2. The hole position rib and the mounting surface rib are integrally formed with the foam body. According to the principle of reducing material waste, reducing production costs, and simplifying the production process, there are no excessive restrictions.

[0033] The hole ribs can be wavy. Experiments have shown that wavy hole ribs can effectively reduce airflow disturbance and reduce airflow noise. Three or more hole ribs can be provided, each 0.5 mm.

[0034] Preferably, multiple auxiliary ribs can be connected between the sides of the mounting surface rib 4 to further improve the sealing effect. On the one hand, providing multiple auxiliary ribs provides several more airflow blocking and sealing functions. On the other hand, the auxiliary ribs are connected to the sides of the mounting surface rib 4, which can improve the overall strength and stability of the mounting surface rib 4 and is not easily deformed or damaged.

[0035] In summary, the present invention provides a foam structure for improving the sealing of the holes in the cover plate of the vehicle's triangular window 1. The foam structure of the rear triangular window 1 is optimized, and three seals can be performed near the hole position. First, the hole rib 3 directly seals the area near the hole position, which can mostly block the airflow; second, the installation surface rib 4 blocks the very small amount of leaked airflow again; third, the overall foam can be compressed as a whole by installation to further block the airflow, which can effectively improve the leakage wind noise caused by poor hole sealing in the triangular window 1, and greatly improve the quietness in the vehicle.
