Description

AIR VENT DIAL FOR VEHICLE
The present invention relates to an air vent dial for a vehicle for improving the click feeling of an air vent dial while achieving cost reduction and quality enhancement.

In general, a vehicle air vent is an air discharge means of an air conditioning system for appropriately maintaining the temperature of a vehicle room and is provided to control a damper mounted on the inside of an air vent so as to control the discharge of air.
The damper in the air vent is rotationally provided with a dial for controlling an air flow rate, wherein a means is provided to the rotation structure of the air vent dial such that an operator can feel the click feeling of a dial.
That is, if a damper control unit is provided to an air vent so as to selectively open or close a damper and to control the flow rate of the air introduced to the inside, the damper control unit includes a dial assembly and a plurality of link members for connecting the damper to the dial assembly.
Herein, referring to Fig. 1, a leaf spring 1' is coupled to a prior art dial assembly for the improvement of clicking feeling, and the leaf spring 1' is applied with click feeling as the leaf spring 1' is pushed backwards by a holding protrusion provided to a dial housing when the dial assembly 30' is rotated. Therefore, selective fixing is realized at a position desired by a user so as to control the air flow rate of the damper.
However, the prior art has a disadvantage that, in the method for applying click feeling by mounting a leaf spring to a dial assembly, the both end portions of the leaf spring are inserted into the dial assembly so as to be coupled thereto such that the leaf spring is pushed backwards by the holding protrusion so as to be deviated from the dial assembly if the dial assembly is rotated.
Further, the leaf spring coupled to the dial assembly is made from a metal material, wherein a coupling process in terms of a manufacturing method using such a metal material is difficult and results in the increase of parts cost due to the rise of manufacturing costs.
In order to resolve the above disadvantage, Korean utility model publication no. 20-0462226 discloses a technique to improve the click feeling of a dial assembly. Referring to Fig. 2, an elastic member 40' made from a plastic material is coupled to a dial assembly 30' so as to improve manufacturing costs and the convenience of assembling work.
That is, the elastic member 40' of the technique is assembled into the dial assembly 30' by fitting one end thereof into a pin in a state, in which the other end thereof is coupled to the dial assembly 30' by the pin, wherein the both end portions are connected by a support part 2' and a protrusion part 3' is formed in the center of the support part 2' so as to be pushed backwards by the holding protrusion of a dial housing.
However, the technique still has a problem that the elastic member 40' has a hole in the one end and a pin-coupling hole in the other end for the assembling of the elastic member 40' into the dial assembly, wherein the hole of the one end is open at one side and the pin-coupling hole has to be formed as an elongated hole such that the pin of the dial assembly is likely to be deviated from the open hole of the one end of the elastic member 40' by vibration and shock, generating malfunction.
In addition, the elastic member is rotated in a state, in which one side thereof is first pin-coupled and then the other end is fitted. Therefore, the dial assembly needs a space for the rotation of the elastic member such that the parts become increased and the assembling work becomes complicated.

an elastic member 40 assembled into the mounting space such that both end portions are held by the hook protrusions 35 and a rear portion is fitted with the fixing protrusion 36 so as to be fixed thereto, and having an elastic portion 41 formed at a front portion and provided with a contact protrusion 42 which comes into contact with the holding protrusion 22 of the dial housing 20.
The elastic member 40 has holding members 43 extending from the both sides of the rear portion thereof so as to further protrude such that the holding members 43 are held by the hook protrusions 35 of the mounting space so as to limit the movement of the elastic member 40.
Further, the fixing plate 32 of the dial assembly 30 is further provided with a deviation prevention protrusion 33 in front of the elastic member 40 which is coupled and fixed to the mounting space so as to prevent the deviation of the elastic member 40.

Hereinafter, embodiments of the present invention will now be described with respect to the configuration in detail with reference to the drawings.
An air vent dial for a vehicle according to the present invention is to improve the click feeling at the time of operating an air vent dial and to achieve the cost reduction and quality enhancement.
First, referring to Fig. 3 and Fig. 4, a damper 11 is rotationally provided to an air path in the air vent housing 10 of an air vent for a vehicle and can open or close the air path by using a link member 12 assembled into a dial assembly 30 which is coupled to the inside of a dial housing 20.
Herein, the dial housing 20 is screw-coupled to the lower portion of the air vent housing 10 and has an opening portion 21 formed in a front portion, a hole formed in a central body portion for the axial coupling of a dial assembly 30 and a fixing protrusion 36 formed on an outer peripheral surface at the rear side of the central body portion.
Further, the dial assembly 30 is rotationally coupled to the dial housing 20 in the center portion thereof and has a dial knob 31 provided to a front portion and fitted into the opening portion 21 so as to be exposed to the outside and a fixing plate 32 extending from a rear portion so as to be connected to the damper 11 by the link member 12 at one side so as to control the opening or closing degree of the damper 11.
As shown in Fig. 5, the rear fixing plate 32 of the dial assembly 30 has a mounting space which is provided with hook protrusions 35 formed at both end portions and a fixing protrusion 36 formed at a rear portion.
The elastic member 40 is assembled into the mounting space such that both end portions are held by the hook protrusions 35 and a concave groove 44 formed on a rear portion is fitted with the fixing protrusion 36 such that the elastic member 40 is fixed to the dial assembly 30. The elastic member 40 has an elastic portion 41 provided with elasticity at a front portion and a contact protrusion 42 formed in the center of the elastic portion 41 so as to come into contact with the holding protrusion 22 of the dial housing 20.
Herein, the elastic portion 41 formed at the front portion of the elastic member 40 is preferably formed by injection-molding so as to have elasticity in such a manner that an elongated hole is formed in the rear portion of the elastic portion 41 so as to form the elastic portion 41 in a relatively thin thickness.
Further, the elastic member 40 has holding members 43 extending from the both sides of the rear portion thereof so as to further protrude such that the holding members 43 are held by the hook protrusions 35 of the mounting space, thereby limiting the movement of the elastic member 40.
Furthermore, the fixing plate 32 of the dial assembly 30 is further provided with a deviation prevention protrusion 33 in front of the elastic member 40 which is coupled and fixed to the mounting space so as to prevent the deviation of the elastic member 40.
That is, the elastic member 40 assembled into the rear fixing plate 32 of the dial assembly 30 is limited in the movement thereof through the firm coupling to the rear fixing plate 32 by the hook protrusions 35, the fixing protrusion 36 and the deviation prevention protrusion 33, and the contact protrusion 42 of the front elastic portion 41 comes into contact with the holding protrusion 22 of the dial housing 20.
Therefore, as shown in Fig. 6, if the dial knob 31 of the dial assembly 30 is rotated, the elastic member 40 at the rear portion moves along the outer peripheral surface at the rear side of the body of the dial housing 20 so as to come into contact with the fixing protrusion 36.
At this time, if the dial knob 31 is further rotated, the contact protrusion 42 which is in contact with the fixing protrusion 36 is pushed backwards with elasticity such that an operator can feel the clicking feeling.
Herein, the elastic member 40 is made from a plastic material. Therefore, differently from the prior art leaf spring made from a metal material, the elastic member 40 does not generate noise even though the elastic portion 41 is elastically deformed at the rotation of the dial knob 31.
The contact protrusion 41 pushed by the fixing protrusion 36 is restored by the elasticity of the elastic portion 41 and moves along the outer peripheral surface of the rear body of the dial housing 20 such that selective fixing is achieved at a position desired by the operator such that the air flow rate is controlled according to the opening or closing of the damper 11 when the dial knob 31 is rotated.
Explaining one embodiment of the present invention configured as above, as the dial knob 31 axially coupled to the dial housing 20 is rotated by the operator, the link member 12 assembled into the rear fixing plate 32 of the dial knob 31 moves together with the elastic member 40.
At this time, the other one end of the link member 12 is connected to the damper 11 such that the damper 11 in the air vent housing 10 rotates in association with the rotation of the dial knob 31 so as to open or close the air path.
Further, in a state, in which the elastic member 40 according to the present invention is coupled and fixed to the dial assembly 30, the contact protrusion 42 protruding from the front elastic portion 41 moves into contact with the outer peripheral surface at the rear side of the body of the dial housing 20.
That is, if the elastic member 40 rotates together with the dial knob 31, the contact protrusion 42 of the elastic member 40 rotates together in contact with the outer peripheral surface of the dial housing 20 and climbs over the holding protrusion 22 provided to the outer peripheral surface of the dial housing 20 at a position that the damper 11 is closed.
At this time, the elastic portion 41 of the elastic member 40 is formed to have elasticity so as to be pushed backwards while the contact protrusion 42 comes into contact with the holding protrusion 22 of the dial housing 20. Therefore, the elastic portion 41 of the elastic member 40 is restored if the elastic portion 41 of the elastic member 40 passes the holding protrusion 22.
Therefore, the operator can recognize the click feeling that the damper is closed by rotating the dial knob 31 and also recognize the click feeling when the damper 11 is opened by rotating the dial knob 31 in the opposite direction such that the contact protrusion 42 of the elastic member 40 climbs over the holding protrusion 22.
Herein, the holding protrusion 22 of the dial housing 20 and the contact protrusion 42 of the elastic member 40 are preferably formed to have rounded shapes such that the contact protrusion 42 can naturally climb over the holding protrusion 22.
