Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning gearbox technology, specifically to an upper housing structure for an automotive air conditioning gearbox. Background Technology

[0002] With the continuous advancement of automotive technology, consumers are demanding increasingly higher levels of comfort from their vehicles. As a key component providing a comfortable in-car environment, the performance and reliability of the automotive air conditioning system are of paramount importance. The automotive air conditioning gearbox, as the power transmission component of the air conditioning system, requires optimized upper housing structure for stable operation of the entire system.

[0003] The existing upper housing structure of automotive air conditioning gearboxes generates excessive noise during use due to the vibrations caused by gear meshing and shaft rotation, which reduces driver comfort. Utility Model Content

[0004] The purpose of this utility model is to provide an upper housing structure for an automotive air conditioning gearbox, which has the advantages of noise reduction and sound absorption, as well as good heat dissipation. It solves the problem that the vibration generated by gear meshing and shaft rotation inside the upper housing structure of current automotive air conditioning gearboxes increases the noise inside the vehicle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an upper housing structure for an automotive air conditioning gearbox, comprising an upper housing device, the upper housing device comprising a base, the base being an annular plate structure, and an upper shell mounted on the top of the base, the upper shell having a plurality of arc seats for mounting gear shafts on its side, a noise reduction mechanism being slidably fitted inside the upper shell, and a sealing mechanism being provided at the bottom of the base.

[0006] Preferably, each of the arc seats has a plurality of heat dissipation fins on its outer edge surface, with one side of each heat dissipation fin adhering to the outer edge surface of the arc seat and the other side adhering to the side surface of the upper shell.

[0007] Preferably, the noise reduction mechanism includes a first damping pad and a second damping pad, wherein the inner edge surfaces of the first damping pad and the second damping pad are provided with sound-absorbing grooves, and the outer edge surfaces are provided with limit strips.

[0008] Preferably, the limiting strip has a T-shaped cross-section and is embedded in the inner edge of the upper shell, and the end of the first shock-absorbing pad facing the second shock-absorbing pad is provided with a sealing block embedded in the second shock-absorbing pad.

[0009] Preferably, the sealing mechanism includes a sealing gasket, the top of which is attached to the lower end face of the base, and a plurality of sealing rings embedded in the arc seat are symmetrically arranged on the sealing gasket.

[0010] Preferably, the sealing gasket has several through holes for bolts to pass through, and the sealing gasket also has a through groove. The vertical cross-section of the through groove is M-shaped, and the through groove avoids the through holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a base, upper shell, arc seat, heat dissipation fins, first damping pad, second damping pad, sound absorption groove and limiting strip, and using the first and second damping pads made of sound-absorbing damping material, can convert the mechanical energy of vibration generated by gear meshing and shaft rotation into heat energy for dissipation. The heat dissipation fins connecting the arc seat and the upper shell conduct heat out, accelerating heat dissipation while also increasing the structural strength of the upper housing equipment.

[0013] 2. This utility model, by setting a sealing gasket, a sealing ring, a through hole, and a through groove, and by setting the sealing gasket on the upper shell of the base and the bottom of the arc seat, and by embedding the sealing ring inside the arc seat, can increase the sealing performance when the upper housing is installed. The through groove opened in the sealing gasket can compress the sealing gasket to deform when the upper housing and the lower housing of the gearbox are connected, thereby increasing the tightness of the connection between the upper and lower housings of the gearbox.
