Vehicle air conditioner mode control panel

Abstract

The invention provides a vehicle air conditioner mode control panel, which comprises a control panel body, two slideways are arranged on the front end surface of the control panel body; the slidewaysare respectively a short slideway and a long slideway; long circular holes are formed in the positions, where the connecting rods or the rocker arms are installed, of the short sliding ways and the long sliding ways, reinforcing ribs for adjusting the mass center of the control panel to the rotating center of the control panel body are arranged on the two end faces of the control panel body, and positioning columns are arranged at the rotating centers of the two end faces of the control panel body and include the first positioning column and the second positioning column. The two slideways drive the three air doors to move, the diameter of the control panel is greatly reduced, the size of the control panel is reduced, and the occupied air conditioner space is small; Meanwhile, stable operation of the control panel is guaranteed, shaking of the control panel in the operation process is eliminated, the angle operation precision of the air door is improved, and the air conditioner qualityis improved.

Description

technical field [0001] The invention relates to the field of vehicle air conditioners, in particular to a vehicle air conditioner mode control panel. Background technique [0002] The mode control panel is a component used to adjust the different rotation angles of each damper in the moving device of the automobile air conditioner, so as to realize different air outlet modes. The mode control panel is designed with track slots for controlling different operating angles of different dampers, which are called slides. According to the number of dampers, the number of slides is generally 1-3. [0003] The mode control panel rotates to control the operation of the damper link (the other end of the damper link is connected to the damper rocker arm), and then controls the movement of the damper, or directly drives the rocker arm connected to the damper to rotate, so as to realize the operation of the damper. The stability and precision will directly affect the rotation angle of th...

AI Technical Summary

Problems solved by technology

[0004] 1. The operation of the control panel is unstable, and the side of the slideway will squeeze the connecting rod or the rocker arm, resulting in increased friction of the moving device. After a long period of use, the accuracy will decrease, the control accuracy of the damper will decrease, and the extrusion will easily produce frictional noise. Or vibration, affecting comfort and NVH performance;

[0005] 2. The movement of the control panel is unstable, which will cause the connecting rod or the rocker arm to be stuck, which will lead to the breakage of the connecting rod or the rocker arm. After the breakage, the operation of the damper cannot be controlled, so that the control of each air outlet mode fails, and the air conditioner cannot work normally;

[0006] 3. The existing control panel has a large volume, and its rotation center is at the center of the circle (see Image 6 As shown), the farther the slideway is from the center of rotation, the more unstable the rotation of the control panel, and the more likely it is to shake, resulting in poor running accuracy of the connecting rod and rocker arm, resulting in improper rotation of the damper angle, air leakage of the air conditioner, and affecting The comfort of the occupants; and when there is air leakage during defrosting, it is very easy to cause fogging on the front windshield, affecting the driving vision and causing the risk of traffic accidents;

[0007] 4. The diameter of the integrated control panel is large, resulting in a large volume of the control panel and taking up a large space for the air conditioner (see Image 6 As shown), at the same time, the product uses a lot of materials, resulting in increased weight and waste of energy, which is not conducive to the lightweight and energy saving of the whole vehicle;

[0008] 5. The axial fixation of the existing control panel is only set on the control side. When the coaxiality of the control panel’s running direction cannot be guaranteed during operation, the control panel will shake, which will cause the connecting rod or rocker arm to not operate properly, and cause the damper to operate. Did not do well
