[0054] Embodiment 1

[0055] In the current automobile industry, the NVH performance is not only directly related to the comfort of passengers and the driving experience, but also reflects the overall manufacturing level and quality of the vehicle; excellent NVH performance can significantly reduce the noise and vibration in the vehicle, reduce the fatigue of the driver and the passenger, and improve the quietness and comfort of driving; at the same time, good NVH performance is also an important embodiment of the competitiveness of the vehicle brand, which helps to improve the market appeal and customer satisfaction of the vehicle. Therefore, in the process of automobile design and manufacturing, the optimization and control of NVH performance is very important.

[0056] In combination with the background art mentioned above, the existing water side module mounting bracket is usually designed to be relatively weak and low in rigidity, especially in the case of long cantilever, the dynamic stiffness of the bracket will be significantly affected; and the dynamic stiffness is an important indicator to describe the deformation resistance of the structure under dynamic load, which is crucial to ensure the stability and reliability of the water side module; due to the poor dynamic stiffness of the mounting bracket, the water side module will be subjected to various vibrations and impacts from the road during vehicle driving, which will be transmitted to the vehicle interior through the mounting point, affecting the comfort of the passengers; at the same time, due to the unsatisfactory vibration isolation effect, these vibrations may also cause damage to other parts of the vehicle body (such as seats, instrument panels, etc.), further reducing the NVH performance of the vehicle.

[0057] In order to solve the above problems, that is, to improve the NVH performance of the vehicle, the present embodiment provides a water side module mounting bracket reinforcing structure, which uses the reinforcing structure to provide greater support to the cantilever end of the water side module mounting point. This scheme improves the stiffness of the connection point, and further improves the dynamic stiffness of the mounting point and the noise sensitivity in the vehicle, thereby improving the NVH performance of the automobile.

[0058] As Figure 1 shown, the embodiment provides a water side module mounting bracket reinforcing structure, the device includes a bracket 3, the bracket 3 is provided with mounting holes, the mounting holes are inserted with studs 3-5, and the studs 3-5 are used to install water side modules; in the embodiment, considering the strength, service life and corrosion resistance of the bracket 3, the bracket 3 is preferably made of stainless steel or stainless steel alloy.

[0059] As Figure 2 shown, in order to improve the structural rigidity of the bracket 3, in the embodiment, the top end of the bracket 3 is connected to the firewall reinforcing vertical beam 2 through bolts, and the bottom end of the bracket 3 is fixedly connected to the vehicle body cross beam 4 through bolts, and before the bracket 3 is connected to the firewall reinforcing vertical beam 2 and the vehicle body cross beam 4, the vehicle body cross beam 4 and the firewall cross beam and the vehicle body cross beam 4 and the firewall panel are respectively connected through the firewall reinforcing vertical beam, so that the firewall reinforcing vertical beam, the firewall cross beam and the firewall panel are closely connected together to form a solid whole; the cantilever of the water side module mounting point bracket is greatly shortened, and the local structural rigidity is greatly enhanced, so as to improve the NVH performance of the vehicle body.

[0060] Compared with the traditional water side module mounting bracket, the bottom of the mounting bracket is only single-sidedly connected to the vehicle body cross beam, the cantilever is usually long, and the water side module is installed and fixed on the cantilever, which leads to insufficient rigidity and further leads to poor vibration isolation effect under various vibrations and impacts from the road; the water side module mounting bracket reinforcing structure provided by the embodiment effectively overcomes the above problems, one end of the reinforcing structure is connected to the firewall reinforcing vertical beam, and the other end is connected to the vehicle body cross beam, which ensures the stability of the water side module installation and improves the safety of the overall structure of the vehicle body.

[0071] As shown in Figure 5 , one side edge of the third side plate 3-3 is connected with the second side plate 3-2, and the other side edge of the third side plate 3-3 is connected with the second reinforcing assembly to form a closed structure.

[0072] In this embodiment, the first side plate 3-1, the second side plate 3-2 and the third side plate 3-3, together with the second reinforcing assembly and the vehicle body cross beam 4, form a three-dimensional cavity structure, which can not only ensure the structural strength but also help to reduce the weight and provide additional buffer space to further improve the NVH performance of the vehicle.

[0075] In the embodiment, the first bending part of the first side plate 3-1 and the end part of the second side plate 3-2 are respectively provided with a second screw hole 6, so that the first reinforcing assembly and the vehicle body beam 4 are fixed through the cooperation of the second screw hole 6 and the bolt, and the requirement of convenient disassembly is met, thereby easily realizing the maintenance and replacement of the components.

[0076] In the embodiment, the middle part of the mounting plate 3-4 is used as a cantilever structure of the whole bracket 3, and it can be seen that the cantilevers of the bracket 3 realize the reinforcement and fixation of the two ends respectively, the length of the whole cantilever is shortened, and the reliability requirement is met; the mounting plate 3-4 and the crank arm 3-6 are designed in an integral molding manner, and the side edges of the two are inwardly folded to form reinforcing ribs 3-7, the design of the reinforcing ribs 3-7 can enhance the anti-deformation ability of the whole structure, and the rigidity and load capacity of the bracket are improved.

[0077] In the embodiment, two second screw holes 5 are provided at the end part of the crank arm 3-6, and the connection with the firewall reinforcing vertical beam 2 is realized through the cooperation of the bolt, where the upper end surface of the crank arm is matched with the lower end surface of the firewall reinforcing vertical beam 2, and the two are designed in a close fit manner, which not only enhances the connection stability of the bracket and the firewall reinforcing vertical beam, but also reduces the vibration and noise.

[0078] It can be seen that the embodiment provides a water side module mounting bracket reinforcing structure, the bracket of the reinforcing structure is formed by using a self-welding process, and the vehicle body beam and the firewall reinforcing vertical beam are connected through bolts, so that the cantilever end of the water side module bracket mounting point is greatly reinforced and supported, the rigidity of the connection point is improved, and then the dynamic rigidity of the mounting point and the noise sensitivity in the vehicle are improved, so that the NVH performance is improved, and the specific advantages are as follows:
