Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile component sealing, in particular to an HVAC sealing structure. Background Art
[0002] With the development of society, the automotive industry has also experienced rapid growth. The HVAC system is an essential system in passenger cars, primarily responsible for regulating the interior temperature and providing a more comfortable driving experience. The HVAC system is typically installed inside the firewall. The air conditioning high and low pressure metal pipes pass through the firewall and connect to the air compressor. The air conditioning water inlet and outlet metal pipes pass through the firewall and connect to the water pump, which is rigidly fixed to the engine body.
[0003] However, existing HVAC systems are sealed by snapping the upper and lower shells together and then attaching a waterproof sponge. If there's a large amount of water outside, it can flow into the vehicle through the gaps in the shells and drip onto the passenger seat, reducing the effectiveness of the HVAC system. Therefore, we've developed an HVAC sealing structure to address this issue. Utility Model Content
[0004] The purpose of the present invention is to provide an HVAC sealing structure to solve the problems raised in the above background technology.

[0007] As a further solution of the present invention: multiple groups of mounting ears are provided on the side wall of the first mounting shell, each of the multiple groups of mounting ears is provided with a group of mounting holes, and each of the multiple groups of mounting holes is provided with a group of mounting bolts.
[0008] As a further solution of the present invention: a plurality of groups of connecting members are provided on the side wall of the second mounting shell, and each of the plurality of groups of connecting members is provided with a group of connecting holes.
[0009] As a further solution of the present invention: the mounting bolts are used in conjunction with the connecting holes.
[0010] As a further solution of the present invention: the number of the mounting ears is the same as that of the connecting piece, and the positions of the mounting ears and the connecting piece correspond to each other.
[0011] As a further solution of the present invention: the thickness of the rubber sealing cover is 8mm-12mm.
[0012] As a further solution of the present invention: the shapes of the first mounting shell and the second mounting shell match each other.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] This HVAC sealing structure, by providing a rubber sealing cover and then pasting a second sealing sponge, prevents water outside the vehicle from flowing into the vehicle through the gap in the shell, thereby playing a sealing role; at the same time, through multiple sets of mounting ears, mounting bolts and connecting parts, the sealing performance of the connection between the first mounting shell and the second mounting shell can be improved, thereby further preventing water outside the vehicle from flowing into the vehicle, which is relatively practical.
