Abstract
The utility model discloses a pull-wire mechanism of an automobile air conditioner hand controller. The pull-wire mechanism of the automobile air conditioner hand controller comprises a knob gear (2), a knob (1) which is coaxially connected with the knob gear (2), a spiral groove gear (3) which is connected with the knob gear (2) in a transmission mode and a pull-wire rocker arm (4), and one end of the rocker arm is connected with a pull-wire. The pull-wire mechanism of the automobile air conditioner hand controller further comprises a spiral sliding chute (5) and an installation shaft. The other end of the pull-wire rocker arm (4) is installed on the spiral groove gear (3), an installation hole is formed in the middle of the pull-wire rocker arm (4), and the installation shaft penetrates through the installation hole, the spiral sliding chute (5) in sequence and is connected with the spiral groove gear (3). By means of the pull-wire mechanism of the automobile air conditioner hand controller, the running control accuracy requirement of the pull-wire is high, by changing the rotation angle of the spiral sliding chute (5) and the size of the pull-wire rocker arm (4), a relative big running range can be achieved, the spiral sliding chute (5) is adopted to drive the pull-wire rocker arm (4) to rotate, the application theory is the worm and gear transmission theory, and thereby the self-locking performance of the pull-wire is high.
Description
Technical field
The utility model relates to a kind of wire-drawing mechanism, is specifically related to a kind of wire-drawing mechanism of automobile air conditioning manual controller.
Background technology
Automobile air conditioning manual controller is low because of its cost, reliability is high, time-to-market is short, is widely used in the air conditioning for automobiles field.Automobile air conditioning manual controller is by the knob on rotary panel, by mechanical transmission structure, operational torque is delivered on the controller rocking arm, moment is transferred in the wire drawing that coordinates with it by rocking arm again, wire drawing is under the drive of rocking arm, transmit torque on the interior A/C assembly air door crank of car, by A/C assembly damper movement in the Sports band motor-car of crank, thereby reach the functions such as the switching of each pattern of air-conditioning and adjustment.
The wire-drawing mechanism of manual air conditioning controller is mainly the form of quadrant gear structure and crowngear structure at present, and the shortcoming of two kinds of structures all is: wire drawing Stroke Control precision is lower, wire drawing control stroke zone is less and the wire drawing self-locking performance is relatively poor.
The utility model content
For the deficiency that prior art exists, the utility model purpose is to provide the wire-drawing mechanism that a kind of Stroke Control precision to wire drawing is high, the automobile air conditioning manual controller that stroke is regional greatly, the wire drawing self-locking performance is higher is controlled in wire drawing.
To achieve these goals, the utility model is to realize by the following technical solutions:
The utility model comprises the wire drawing rocking arm that knob gear, the plug helix gear that is in transmission connection with the coaxial knob that is connected of knob gear, with knob gear and an end are connected with wire drawing, and the utility model also comprises spiral chute and installation shaft; An other end of wire drawing rocking arm is arranged on the plug helix gear, is provided with mounting hole at the middle part of wire drawing rocking arm, and installation shaft is passed mounting hole successively, spiral chute is connected with the plug helix gear.
Above-mentioned wire drawing rocking arm is arranged on the plug helix gear by fixing swing pin.
What above-mentioned installation shaft specifically adopted is sliding pin.
The utility model is high to the Stroke Control precision of wire drawing, because the initiating terminal of spiral chute just determines the anglec of rotation of wire drawing rocking arm, so can because of the gap error between gear, not affect the angle of wire drawing rocking arm in the fitting process of reality; The utility model can be realized larger travel range by the anglec of rotation of change spiral chute and the size of wire drawing rocking arm; The utility model adopts spiral chute to drive the wire drawing rocking arm and rotates, and the principle of application is the transmission principle of worm and gear, so higher to the self-locking performance of wire drawing.
Description of drawings

Fig. 2 is the structural representation that the utility model does not comprise knob and knob gear;
Fig. 3 is schematic diagram of the present utility model (in figure, F represents to be subjected to force direction);
Fig. 4 is motion process design sketch of the present utility model.
Each label in figure: 1, knob, 2, knob gear, 3, the plug helix gear, 4, the wire drawing rocking arm, 5, spiral chute, 6, sliding pin, 7, fixing swing pin;
Wherein, A1 represents the knob hand of rotation, and A3 represents plug helix gear hand of rotation, and A4 represents wire drawing rocking arm sense of motion.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
The utility model adopts the mode of screw drives to control the anglec of rotation of wire drawing Rocker arm 4, thereby realizes control and self-locking to the wire drawing stroke.
Referring to Fig. 1 and Fig. 2, the present embodiment comprises knob gear 2, the plug helix gear 3, the wire drawing Rocker arm 4 that is positioned at plug helix gear 3 back sides, spiral chute 5 and the sliding pin 6 that are in transmission connection with the coaxial knob that is connected 1 of knob gear 2, with knob gear 2 fronts.
Right-hand member at the wire drawing Rocker arm 4 is connected with wire drawing (not shown in FIG.), the left end of wire drawing Rocker arm 4 is arranged on plug helix gear 3 by fixing swing pin 7, be provided with mounting hole (not marking in figure) at the middle part of wire drawing Rocker arm 4, sliding pin 6 passes mounting hole, spiral chute 5 be connected with plug helix gear 3 (being that spiral chute 5 is between wire drawing Rocker arm 4 and plug helix gear 3) successively.
Referring to Fig. 3 and Fig. 4, the working process of the present embodiment is as follows:
At first rotate knob 1, rotate thereby knob 1 drives knob gear 2; And then knob gear 2 drive plug helix gears 3 clockwise rotate; Plug helix gear 3 clockwise rotates drive spiral chute 5 and does the left-hand revolution motion; Spiral chute 5 is done the left-hand revolution sport to the directed force F that sliding pin 6 produces perpendicular to the helix line normal orientation, forces sliding pin 6 to do the left-hand revolution motion; Sliding pin 6 is done the left-hand revolution motion and then is driven wire drawing Rocker arm 4 left-hand revolution.
The utility model is high to the Stroke Control precision of wire drawing.Because the initiating terminal of spiral chute 5 just determines the anglec of rotation of wire drawing Rocker arm 4, so can because of the gap error between gear, not affect the angle of wire drawing Rocker arm 4 in the fitting process of reality.
The utility model can be realized larger travel range by the anglec of rotation of change spiral chute 5 and the size of wire drawing Rocker arm 4.
The utility model adopts spiral chute 5 to drive the wire drawing Rocker arm 4 and rotates, and the principle of application is the transmission principle of worm and gear, so higher to the self-locking performance of wire drawing.
Above demonstration and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
