Problems solved by technology

[0003] If the materials of the two moving parts are the same, problems such as abnormal friction and noise will easily occur during the movement, which will affect the comfort of the driver and passengers; if the parts are made of different materials, it will inevitably increase the cost

Embodiment Construction

[0011] Such as figure 1 The damper movement mechanism of an automobile air conditioner is shown, which includes a damper 1, a damper lever 2, and a dial 3. The dial 3 is provided with a track groove 4, and the end of the damper lever 2 is provided with a track groove 4 and a track groove 4. A cylindrical boss with rolling friction on the inner wall, a sheath 5 is sleeved on the outer wall of the cylindrical boss, and the sheath 5 is a PA66 nylon sheath.

[0012] This mechanism uses wire drawing to drive the disc-shaped dial to rotate, and directly controls the synchronous movement of the three dampers through the disc-shaped dial, so as to meet the air supply requirements required by the design.

[0013] Firstly, the driving force comes from the soft drawing disc fixed on the disc-shaped dial. The drawing disc is controlled by the manual panel, and the control dial rotates around the rotating shaft. At this time, the sheath makes relative rolling motion in the track groove of ...

Abstract

The invention discloses an automotive air conditioning damper moving mechanism which comprises a damper, a damper poking rod and a drive plate. A track groove is arranged on the drive plate, an end of the damper poking rod is provided with a cylindrical boss extending into the track groove and having rolling friction with an inner wall of the track groove, and a sheath is sleeved on an outer wall of the cylindrical boss. By means of the structure, the automotive air conditioning damper moving mechanism has the advantage that the sheath structure enables two components in the drive plate, the poking rod and the sheath to be in opposite rolling motion, materials of the two opposite moving components are different, moving is stable, friction resistance is small, and transmission noise is low; the moving mechanism is compact, simple in transmission process, simple and clever in structure; the damper can be taken to a preconceived design position, and control is precise and stable and noise is low during the process; and all components of the transmission mechanism rotate around the normal axis of the casing, and occupied space is small.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to an automobile air conditioner damper movement mechanism. Background technique [0002] The air outlet modes of the air-conditioning system are all in different states of the three dampers in the air-conditioning assembly, which are air blowing, defrosting, and foot blowing, forming ventilation, semi-ventilation, and wind-blocking states, so that the entire air distribution system forms 5 different air outlets. wind pattern. The damper is matched with the lever, and the guide column of the lever is matched with the track groove of the dial. The rotation of the dial drives the movement of each lever, so that the damper rotates in different angles in the housing, so that the air outlet can achieve ventilation, semi-ventilation and no wind. status. During this movement, it is a sliding process between the driving lever and the dial, and its frictional force is s...
