Abstract
The utility model relates to a transmission structure of air-conditioning controller knob, comprising a knob, a transmission gear in transmission connection with the knob, and an output gear in transmission connection with the transmission gear. The transmission structure is characterized in that an external gear which is engaged with the transmission gear is arranged on the knob, and the teeth number of the external gear is more than that of the transmission gear; and that the transmission gear and the output gear is internal gearing. Compared with the prior arts, the transmission structure of the utility model has the advantages that the transmission gear is designed as external gearing transmission, so that buttons can be directly arranged on the knob, thereby requiring no positions prepared for the buttons; that occupied space is decreased so that the knob structure is more compact; that the teeth number of the external gear is designed to be more than that of the transmission gear, so that output angles differ form input angles according to transmission ratio distribution; that the structure is stable, accurate and reliable in transmission, so that the service life can reach more than 50000 times.
Description
Technical field
The utility model relates to controller knob structure, specifically refers to a kind of automotive air-conditioning controller knob drive mechanism.
Background technology
The air conditioning for automobiles hand controller all is to adopt the mode of knob and button split to design basically at present, and its size is bigger, and it is bigger therefore to take up room, and the installation site of other parts of automobile is affected.Simultaneously, its input and output of existing controller knob are transmissions on year-on-year basis, i.e. the input angle of knob work is consistent with the output angle of controller, and it is bigger therefore influenced by overall dimension, need to do to improve further.
Summary of the invention
The utility model technical problem to be solved is to first present situation by technology a kind of air-conditioning controller knob drive mechanism that can amplify gearratio and take up room little to be provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this air-conditioning controller knob drive mechanism; The travelling gear that comprises knob, is in transmission connection with this knob, the output gear that is in transmission connection with described travelling gear; It is characterized in that: said knob is provided with the external gear with said travelling gear external toothing, and the number of teeth of said external gear is greater than the number of teeth of said travelling gear; Said travelling gear and said output gear are interior engagement.
Described travelling gear can be arranged on the printed substrate through fixed mount; Said knob is provided with the button that can touch this printed substrate.
Preferably, said printed substrate is provided with emitting led, and is coated with the light guide that light is evenly seen through on the said printed substrate.Light guide can mildly be derived the emitting led light that emits.
As improvement; Described knob can be fixed on described knob and be arranged on the described light guide; Said light guide is provided with the groove towards said printed substrate; The bottom surface that described knob portion is passed this groove is contained in this groove described external gear, and described travelling gear passes described printed substrate and described external gear meshes in said groove.
Compared with prior art, the utility model is designed to the external toothing transmission with travelling gear, and button can be set directly on the knob, does not need extra reservation key position again; Reduced shared space, made that the structure of knob is compact more; The number of teeth of external gear then can be distributed according to gearratio greater than the design of the number of teeth of said travelling gear, makes the output angle be different from the input angle; Working stability during transmission, transmission accurately, reliable, can reach more than 50000 times useful life.
Description of drawings
Fig. 1 is the solid intention of the utility model embodiment decomposition texture.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, this air-conditioning controller knob drive mechanism comprises: parts such as knob 1, external gear 2, light guide 3, printed substrate 4, travelling gear 5, fixed mount 6 and output gear 7.
Wherein knob 1 is arranged on air-conditioner controller panel outside, and external gear 2 is arranged on the internal port of knob 1, and the knob 1 in the present embodiment is formed in one with external gear 2.Knob 1 is fixed on the light guide 3 with external gear 2 together, and light guide 3 is transparent, can evenly mildly light conducted.Light guide 3 covers on the side of printed substrate 4, also is provided with on this printed substrate 4 to be used for emitting led 8 of indicating operating status.Printed substrate 4 is provided with the through hole 9 that supplies travelling gear 5 to pass with light guide 3.Travelling gear 5 is the connector of external gear 2 and output gear 7, its pass through hole 9 and external gear 2 external toothings, with output gear 7 in engagement.Also be fixed with fixed mount 6 on another side of printed substrate 4, travelling gear 5 is installed on the fixed mount 6; Fixed mount 6 also has the effect of knob location and control gear.Output gear 7 is an internal gear, is used for the output of controller angle, connects the HVAC controller system through soft drawn silk parts simultaneously.
The number of teeth of aforementioned external teeth wheel and output gear is all greater than the number of teeth of travelling gear.
This air-conditioning controller knob drive mechanism adopts external gear, travelling gear, the output gear secondary kind of drive that the input of knob and air-conditioner control system is linked together; Promptly drive travelling gear by the external gear on the knob; Drive output gear by travelling gear again, thereby reach the output of operating angle, inner space that simultaneously can vacant knob; Parts such as button conveniently are set in the knob space; Simplify the structure, the shared space of this knob drive mechanism is littler, makes the more compact structure of entire controller panel; The number of teeth of external gear and output gear all then can be distributed according to gearratio greater than the design of the travelling gear number of teeth, makes the output angle be different from the input angle.
