Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile accessories, in particular to a damping type wave-preventing device. BACKGROUND

[0002] The existing patent with the publication number CN212499881U discloses a spring energy-absorbing type fuel tank wave-preventing plate, which adopts two baffles. The opposite sides of the two baffles are connected by elastic devices, and the opposite sides are respectively connected with the inner wall of the fuel tank by elastic devices. When the car decelerates, the oil in the fuel tank gathers to the front side of the fuel tank, and the oil impacts the baffle to move it forward. At this time, due to the elastic deformation of the elastic element, the kinetic energy of the baffle is converted into the elastic potential energy of the elastic element, which reduces the impact strength of the oil on the inner wall of the fuel tank, thereby reducing the noise generated by the impact of the oil. However, during the driving process of the car, the situation is variable. Not only acceleration and deceleration, but also turning and bumping. Therefore, the movement direction of the oil is complex and variable, and the moving direction of the above-mentioned baffle is limited to the front and back directions, and the noise reduction effect is not good. SUMMARY

[0003] The purpose of the present application is to overcome the shortcomings of the prior art and provide a damping type wave-preventing device with multi-dimensional wave-preventing and improved noise reduction effect.

[0004] To achieve the above-mentioned purpose, the technical scheme adopted by the damping type wave-preventing device of the present application is:

[0006] Preferably, the damping element comprises a first pipe body and a second pipe body, a groove is formed in the front end of the first pipe body, a baffle is accommodated in the groove, an inner thread is arranged on the inner side wall of the groove, a first anti-falling boss is arranged at the tail end of the first pipe body, a boss is arranged at the front end of the second pipe body, an outer thread matched with the inner thread is arranged on the outer peripheral wall of the boss, and a second anti-falling boss is arranged at the tail end of the second pipe body.

[0011] Compared with the prior art, the damping type wave-proof device has the following advantages:

[0012] 1. When the oil liquid in the oil tank surges, the damping member on the horizontal plate, the vertical transverse plate and the vertical longitudinal plate slides in the bushing, and the damping member hinders the movement of the oil liquid in multiple dimensions, cooperates with the small hole, disperses and reduces the kinetic energy of the oil liquid, so as to slow down the impact of the oil liquid on the inner wall of the oil tank, and improve the noise reduction effect.

[0013] 2. The horizontal plate, the vertical transverse plate and the vertical longitudinal plate used for manufacturing the wave-proof support can adopt a relatively thin metal plate, which not only saves cost, but also meets the design requirement of light weight of the whole vehicle, the large hole on the horizontal plate, the vertical transverse plate and the vertical longitudinal plate is thickened through the shaft sleeve, so as to avoid forming an edge at the position and reduce the wear of the damping member, thereby prolonging the service life of the damping member.
