Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.

It should be noted that the features of the embodiments of the present application may be combined with each other without conflict.

At present, automobiles are common vehicles for people to go out, and the automobiles also meet the NVH (Noise, Vibration, Harshness, English abbreviation for Noise, Vibration and Harshness) characteristics on the premise of meeting the convenience of people going out. NVH is a comprehensive problem for measuring automobile manufacturing quality, research on NVH characteristics is not only suitable for the whole automobile new product development process, but also suitable for improving the riding comfort of the existing automobile type, and the riding comfort is improved by improving the vibration condition (amplitude reduction or frequency shift) of an excitation source or controlling the transmission of vibration noise of the excitation source to the automobile chamber.

In the development process of the automobile part product, the structural performance of the part product needs to be verified so that the structural design of the part product meets the NVH characteristic requirement when the part product is installed in a whole automobile. In case that after the vehicle is used for a period of time, the wear or actual use condition of some parts can have a significant influence on the NVH characteristic of the whole vehicle.

The automobile shock absorption assembly comprises a spring pad upper support which is used for being connected with an automobile body longitudinal beam in a matched mode. During the early design and development of the spring cushion upper support, various performances of the components (for example, corrosion resistance, weather resistance, low temperature resistance, high temperature resistance, strength, durable service life and the like of the spring cushion upper support) are generally considered, and the various performances of the spring cushion upper support meet the requirements during the design.

However, when the upper support of the spring pad is installed on the whole vehicle, and the vehicle is in the driving process, the specific use condition where the upper support of the spring pad is located is different from the verification environment during early design, which often results in deviation between the actual performance of the upper support of the spring pad in the use process and various performances verified during early design.

The spring cushion upper support is in a sealing state after being matched with a vehicle body longitudinal beam in an earlier development process. The vehicle is at the in-process of traveling, no matter when the vehicle passes through what kind of road conditions, and the spring pad is gone up the support and is in encapsulated situation with automobile body longeron junction all the time, can not exert an influence to the inside structure of support on the spring pad.

However, the inventor finds that the connecting structure between the automobile shock absorption assembly and the vehicle body longitudinal beam is easy to have a structure aging phenomenon after the automobile is used for a period of time, particularly after a wading road surface. Even when severe, the position between the shock absorbing assembly of the vehicle and the body side member can generate the NVH noise of knocking, and the phenomenon greatly influences the good experience of users.

Based on the above problem, the embodiment of the application provides a vehicle spring cushion upper support. The support on the vehicle spring pad belongs to a part in a vehicle damping assembly, is matched with a spring upper pad in the vehicle damping assembly, and is used for improving the NVH noise and the structure aging phenomenon of knocking at the position between the damping assembly and a vehicle body longitudinal beam of the existing vehicle.

Referring to fig. 1, a cross-sectional view of a seat 100 on a vehicle spring mat according to an embodiment of the present application is shown.

The seat 100 for a vehicle spring mat may include a first fitting portion 110, a connecting portion 120, and a second fitting portion 130 fixedly connected, and the connecting portion 120 is connected between the first fitting portion 110 and the second fitting portion 130. And the second fitting portion 130 and the connecting portion 120 define a limiting structure, and the limiting structure is used for being matched and connected with an upper spring pad in the automobile shock absorption assembly.

Specifically, the first fitting portion 110 is an annular structure, and the first fitting portion 110 extends along its own axial direction. The second fitting portion 130 is also an annular structure, and the second fitting portion 130 also extends along its own axial direction. The connecting portion 120 is connected to an end of the first mating portion 110, and the second mating portion 130 is connected to an end of the connecting portion 120 away from the first mating portion 110, thereby forming an integral structure. In other words, the seat 100 may be integrally formed, and may be a column structure with one end being larger and the other end being smaller, and the axial direction of the seat 100 is the axial direction of the column structure.

Alternatively, the central axis of the first fitting part 110 and the central axis of the second fitting part 130 may coincide. The first mating portion 110 is adapted to mate with a tray on a vehicle body rail, and the second mating portion 130 is adapted to mate with a spring upper pad.

When the automobile shock absorption assembly is assembled, in order to enable the upper spring pad to be sleeved on the limiting structure formed between the second matching portion 130 and the connecting portion 120, the upper spring pad can be limited by the connecting portion 120. Optionally, the diameter of the first fitting portion 110 is greater than the diameter of the second fitting portion 130, and the connecting portion 120 is connected between the first fitting portion 110 and the second fitting portion 130 in a transition manner, so that the seat 100 has a step in the axial direction on the vehicle spring pad, and the spring pad can be fixedly connected to the step.

The cavity 131 is formed in the second matching portion 130, so that the structural weight of the support 100 on the vehicle spring cushion can be reduced, and the purposes of reducing weight and saving material cost are achieved.

Because support 100 is installed in whole car and use after a period on the vehicle spring cushion, especially when crossing the road conditions of wading, the wheel causes the ponding on the road surface of wading to splash easily, and partial ponding can enter into the cavity 131 of second cooperation portion 130 from support 100 on the vehicle spring cushion, and the ponding that gets into in the cavity 131 that splashes is dirty water mostly, and has debris such as gravel, silt incidentally. Ponding not only can cause vehicle spring pad to go up support 100 easily and rust, leads to structural strength to descend, and long-time storage can make the vehicle produce certain NVH noise of knocking when serious in cavity 131 moreover.
