The to-be-solved technical problem of the utility model is to overcome current defect, provide a novel vehicle air conditioner of air door drive structure, prevent that the rocking arm from droing, design mistake proofing structure can effectively prevent the wrong dress, improves assembly efficiency and quality, and this structure mould simple structure, and the machining precision requirement is lower, and the mould is with low costs, and it is convenient to dismantle simultaneously, and the later maintenance of being convenient for can effectively solve the problem in the background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel vehicle air conditioner of air door drive structure, includes rocking arm and air door, be provided with fan-shaped spline on the rocking arm, the front end of rocking arm is provided with the conical head, and the middle part of rocking arm is provided with the polished rod, be provided with the shaft hole on the air door, be provided with the spline groove on the shaft hole inner wall, be provided with the inclined plane in the shaft hole.
Furthermore, the number of the fan-shaped splines is 3, and the angles of the fan-shaped splines are different.
Furthermore, the spline grooves are correspondingly matched with the fan-shaped splines, and the spline grooves and the fan-shaped splines play a limiting and mistake-proofing role in the radial direction, so that wrong assembly is effectively prevented, and the assembly accuracy is improved.
Furthermore, the inclined plane is correspondingly matched with the conical head, the conical head is limited through the inclined plane, the rocker arm is prevented from falling off, and the safety and the reliability of the driving structure are guaranteed.
Furthermore, the diameter of the polished rod is smaller than that of the rocker arm, the polished rod deforms under the action of the conical head at the front end of the fan-shaped spline and the inclined plane, and finally the polished rod resets when the rocker arm is inserted into the bottom end, so that the conical head and the inclined plane are matched in place, assembly is facilitated, and assembly efficiency is improved.
Compared with the prior art, the beneficial effects of the utility model are that: this novel vehicle air conditioner of air door drive structure has following benefit:
1. the utility model discloses on set up the spline groove, radially play spacing and mistake proofing effect through spline groove and fan-shaped spline, the effectual mistake proofing dress that prevents improves the accuracy of assembly, restricts the conical head through the inclined plane, prevents that the rocking arm from taking place to drop, has guaranteed drive structure's safe and reliable.
2. The utility model discloses on set up the polished rod, under fan-shaped spline front end conical head and inclined plane effect, the polished rod takes place deformation to the polished rod resets when the bottom end is inserted to the rocking arm finally, makes conical head and inclined plane cooperation target in place, is convenient for assemble, improves assembly efficiency.
3. The utility model discloses can effectually prevent that the rocking arm from droing, design mistake proofing structure can effectively prevent the misloading, improves assembly efficiency and quality, and this structure mould simple structure, and the machining precision requirement is lower, and the mould is with low costs, and it is convenient to dismantle simultaneously, the later maintenance of being convenient for.
