Technical Field
The utility model relates to the technical field of automobile shock pads, in particular to a new energy automobile battery cooler shock pad.
Background
The new energy automobile power battery is used as the power source of the automobile, and the heat generated by charging and discharging can always exist. The performance of the power battery is closely related to the battery temperature, in order to extend the service life of the power battery as much as possible and obtain maximum power, the storage battery needs to be used in a specified temperature range, and in principle, the actual battery temperature is in an operable state in the range of-40 ℃ to +55 ℃. Therefore, the power battery units of the new energy are all provided with cooling devices at present so as to be used for controlling the temperature of the battery and ensuring the use of the battery.
In order to ensure the service lives of the battery and the cooler, and avoid the faults caused by the vibration, the shock pad is required to be arranged for absorbing the vibration energy. The shock pad is used as an important part for bearing and damping the battery cooler, and mainly plays roles of bearing the whole battery cooler assembly and buffering vibration and jolt generated in the running process of the automobile so as to prevent the whole battery cooler from being damaged due to high-strength collision, and meanwhile, noise can be reduced, and the running stability, comfort and safety of the automobile are improved. However, because the road conditions through which the vehicle passes are different when the vehicle runs, the vibration generated by the whole vehicle is different, the existing shock pad is mainly used for ensuring the durability of a cooling system, only the shock energy can be absorbed in the same state, and the different shock absorption and buffering conditions under normal and limit working conditions are not involved, for example, the existing Chinese patent publication No. CN202531733U discloses a shock pad of an electric vehicle condenser, which comprises a shock pad body and a drill bit part, wherein a connecting part for enabling the shock pad to be installed in a frame hole of the electric vehicle is arranged between the shock pad body and the drill bit part; the structure of the shock pad body can only play a role in shock absorption and buffering in a fixed mode.
Disclosure of Invention

the axial dimension of the first-order shock absorber is larger than that of the second-order shock absorber.
As a further scheme of the utility model: the hollow structure is internally and fixedly provided with a plurality of supporting ribs, and the supporting ribs are uniformly distributed around the axis of the first-order shock absorber.
As a further scheme of the utility model: an annular gap is formed in the middle of the outer circular surface of the second-order shock absorber.
As a further scheme of the utility model: the first-order shock absorber is cylindrical.
As a further scheme of the utility model: an annular groove is formed in the inner wall of the first-order shock absorber.
As a further scheme of the utility model: and round corner structures are arranged at two ends of the first-order shock absorber.
As a further scheme of the utility model: the first-order shock absorber, the second-order shock absorber and the supporting ribs are all made of rubber materials.
The novel energy vehicle battery cooler shock pad has at least one of the following technical effects:
because the length of the first-order shock absorber is longer than that of the second-order shock absorber, under normal working conditions, namely, the vibration amplitude of the vehicle is in a normal state, such as a state when the vehicle runs on a relatively flat road surface in a city, at the moment, the first-order shock absorber plays a main role in shock absorption and buffering, when the vibration and vibration amplitude of the vehicle are large, such as the vehicle passes through a relatively poor road condition position, the vehicle integrally vibrates greatly, at the moment, the first-order shock absorber cannot completely meet the shock absorption requirement, the first-order shock absorber is pressed and then continues to press the second-order shock absorber, and the second-order shock absorber and the first-order shock absorber play a role in shock absorption and buffering together; therefore, through the structural arrangement of the two-order shock absorber, the device can exert different shock absorption effects under different working conditions, and the service life of the whole shock pad can be ensured through the two-order shock absorber while the shock absorption effect is ensured; further, the device is also provided with a hollowing structure, and the rigidity of the device in the axial direction and the radial direction can be simultaneously reduced through the hollowing structure, so that the damping performance of the damping pad in the axial direction and the radial direction can be simultaneously enhanced.
