Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mounting bracket technology, and specifically relates to a mounting bracket for AVAS modules. Background Technology
[0002] The AVAS module, or Vehicle Acoustic Warning System module, is an active safety device on new energy vehicles (pure electric vehicles, plug-in hybrid electric vehicles, etc.). Its core function is to remind pedestrians and non-motorized vehicles around the vehicle to notice the low-speed new energy vehicle by simulating specific sounds, thus compensating for the safety hazards caused by its "silent" characteristics.
[0003] The AVAS module is mounted on a bracket. Because the AVAS module generates a lot of heat when it is working, heat dissipation holes are often made on the bracket. However, the diameter of the heat dissipation holes is generally small, and the heat dissipation effect is limited. If the diameter of the heat dissipation holes is increased, a lot of dust and other substances will enter the inside of the bracket, which will have an adverse effect on the AVAS module. In addition, the existing brackets are often installed inside the protective plate of the vehicle chassis. In this way, the AVAS module is completely wrapped by the protective plate, the air circulation is obstructed, and heat is easy to accumulate. Utility Model Content

[0021] The present invention is further configured such that a damper is fixedly connected to the bottom of the bracket, and a buffer spring is wound around the surface of the damper.
[0022] By adopting the above technical solution, dampers and buffer springs can be set to facilitate vibration reduction of the support and reduce the sway amplitude of the support and AVAS module.
[0023] The present invention is further provided that a sealing ring is bonded to the penetration point between the condenser tube and the left side of the bracket.
[0024] The above technical solution involves setting a sealing ring to seal the bracket, preventing dust and other external environmental factors from adversely affecting the AVAS module.
