Description

A New Structure to Increase the Inching Stiffness of Radiator Installation

technical field

The utility model relates to a connection structure of automobile components, in particular to a structure for enhancing the inching stiffness of the installation under the automobile radiator.

Background technique

With the advancement of automobile design technology and production technology, in the process of vehicle design, the requirements for NVH are getting higher and higher, and then the requirements for dynamic stiffness of each installation point of the car body are also becoming more stringent. NVH refers to (noise, vibration, harshness), that is, the noise, vibration, and harshness of the car. It studies the changes in the comfort of the occupants and the smoothness and stability of the car under the action of the vibration and noise in the car cabin. It is one of the most concerned projects in the research and development of automobiles to analyze the impact of each system and the matching between each system on NVH, and to select the best design parameters.

The car radiator is an important part of the car. It is generally installed and fixed in the engine compartment of the front end of the car through the upper and lower radiator brackets. The dynamic stiffness of the lower mounting point refers to the connection structure between the radiator and the fuselage through the radiator lower bracket. In the dynamic process of stiffness, the structure of the lower bracket of the radiator is one of the important factors affecting the inching stiffness of the lower installation.

The common lower bracket of the radiator is a stamped part of single-layer steel sheet. There are some reinforcing ribs on the bracket to improve its rigidity and strength. Under static conditions, the upper and lower brackets of the radiator are sufficient to ensure the fixing and support of the radiator. However, in dynamic conditions, especially when the car is running on complex roads, the shaking of the radiator will generate a large moment arm, and the torsional force and bending force generated by the moment arm will act on the lower bracket of the radiator. The rigidity of the lower bracket of the radiator of the layer structure is poor, and the lower bracket of the radiator will be partially deformed or twisted, which will cause the radiator to vibrate in dynamic conditions. The vibration will not only generate noise and affect the NVH performance of the vehicle, but also affect the heat dissipation. The connection reliability of the installation point under the device.

By changing the structure of the lower bracket of the radiator to improve the ability of the lower bracket of the radiator to resist torsion and bending force, it is the best way to improve the inching stiffness of the installation under the radiator, prevent the vibration of the radiator, improve the NVH performance of the vehicle, and improve the reliability of the radiator installation. The essential. The prior art provides some technical solutions, such as a technical solution for the installation of a radiator announced on September 6, 2006, as the Chinese patent announcement number is CN2813376, the name is "automobile radiator protection device", and the announcement date is September 6, 2006. The connection mode between the radiator and the lower bracket of the radiator is improved, but the disadvantage is that the vibration of the radiator is not prevented by increasing the dynamic stiffness of the mounting point under the radiator.

Contents of the invention

The utility model solves the technical problem that the structure of the lower bracket of the automobile radiator in the prior art has poor resistance to torsion force and bending force, resulting in poor inching rigidity of the installation under the radiator, and provides a method to prevent the radiator from being generated under dynamic conditions. Vibration, radiator mounting point structure to improve radiator installation reliability.

In order to solve the above technical problems, the utility model adopts the following technical solutions: a new structure for increasing the inching stiffness of the lower installation of the radiator, the structure includes the lower bracket of the radiator, the middle part of the lower bracket of the radiator is provided Both ends are provided with symmetrical beam connection cover plates, and the beam cover plate and the beam connection cover plate are fixedly connected with the lower bracket of the radiator.

The utility model improves the dynamic stiffness of the mounting point of the radiator by improving the structure of the lower bracket of the radiator. The method is to add a cover plate to the middle part and both ends of the lower bracket of the radiator. The function of the cover plate is to enhance the stress of the lower bracket of the radiator. The strength and rigidity of the more concentrated parts, the principle is that the additional cover plate is combined with the original structure of the lower bracket of the radiator to form an integral cavity structure, which greatly improves the performance of the radiator under the radiator. The rigidity of the bracket, in particular, improves the ability of the bracket under the radiator to resist torsional and bending forces.

The lower bracket of the radiator is provided with a lower bracket beam, and the two ends of the lower bracket beam are provided with symmetrical lower bracket columns, and the lower bracket beam is fixedly connected with the lower bracket column; The bracket beam is fixedly connected; the two ends of the lower bracket beam, the junction of the lower bracket beam and the lower bracket column are provided with a beam connection cover, and the beam connection cover is fixedly connected with the lower bracket beam and the lower bracket column; the lower bracket beam, the lower bracket Columns, beam cover plates, and beam connection cover plates are all stamped parts with equal wall thickness.

The lower bracket of the radiator in the prior art is composed of the lower bracket beam and its two ends respectively fixedly connected with a lower bracket column. The utility model adds a beam cover plate to the middle part of the lower bracket beam; An additional beam is connected to the cover plate at the junction with the column of the lower support; the additional cover plate is fixedly connected to the lower support. The purpose of the partial additional cover plate on the lower bracket of the radiator instead of the integral additional cover plate is to facilitate the installation of the bracket and reduce the weight of the bracket.

The utility model greatly improves the dynamic stiffness of the installation point under the radiator through the simple structure change of the lower bracket of the radiator, and plays a great role in preventing the vibration of the radiator, preventing the generation of vibration noise, and increasing the reliability of radiator installation. It has a good effect and has the beneficial effect of improving product quality and improving product quality.
