A damper control device for vehicle air conditioner and vehicle

Abstract

The invention provides a damper control device of a vehicle-mounted air conditioner and a vehicle, belonging to the field of vehicle-mounted air conditioners. The damper control device includes: a drive motor; and a worm gear transmission, including: a worm driven by the drive motor; a first worm wheel and a second worm wheel both meshed with the worm, and the first worm wheel passes through the first unit The direction rotating bearing is connected with the first target damper blade shaft, and the second worm gear is respectively connected with the second target damper blade shaft through the second one-way rotating bearing, and the freely rotatable direction of the first one-way rotating bearing is the same as that of the first one-way rotating bearing. The freely rotatable direction of the second one-way bearing is opposite, so that the first worm wheel can only drive the first target damper blade shaft in the first direction, and the second worm wheel can only drive the first target damper blade shaft in the second direction. The second target damper blade axis, the first direction is opposite to the second direction. The damper control device of the present invention can save costs.

Description

technical field [0001] The invention belongs to the field of vehicle-mounted air conditioners, and in particular relates to a damper control device of a vehicle-mounted air conditioner and a vehicle. Background technique [0002] Car air conditioners generally have air outlets, air ducts, and dampers. At present, the dampers of most cars are integrated with the air outlets, and the air outlets in different positions share the same air duct, which cannot be automatically and independently controlled. Users can manually open the damper or adjust the air volume and direction of the air outlet according to actual needs, which is not very convenient to operate. [0003] With the increasing maturity and development of automobile technology, the requirements for the operability and comfort of automobiles are getting higher and higher. Some cars have used different air ducts to correspond to the air outlets in different positions, and even how many air outlets are in the same positi...

AI Technical Summary

Problems solved by technology

Now with the increase in the number of air ducts, the corresponding control system and the number of motors also need to increase, so the cost of the control system will also increase exponentially, so the development and application of this technology are restricted to a certain extent due to the cost problem
