Description

[Detailed description of the invention] This invention is a damper switching system for automobile air conditioners.
This invention relates to a moderation mechanism for an operating lever that controls operations such as switching a multi-stage air flow rate adjustment switch and changing the resistance value of a variable resistor.

Conventionally, this type of moderation mechanism for an operating lever has a protruding slider attached to the operating lever via an elastic member made of a leaf spring, and the slider is pressed against a guide plate of the operating lever. It is being done. The portion of the guide plate on which the slider slides is provided with an arbitrary number of clicks consisting of moderation recesses formed at appropriate intervals, and when the slider falls into these clicks, the operating lever is The structure is such that moderation is maintained.

However, in conventional devices such as those mentioned above,
If the operating force applied to the control lever is large, the slider of the control lever will go over the click on the guide plate and will not stop at the position that requires moderation, so correction is required to return the control lever to the specified position. It has the disadvantage of being.

The present invention has been developed in view of the above points, and includes protrusions on the operating lever and the guide plate so that these protrusions interfere with each other at positions where moderation of the operating lever is required. This interference relationship is canceled when the force is removed, and by applying further operating force, the protrusion can be moved to the next interfering position, making it easy to apply and remove operating force to the operating lever. The control lever can only be moved to the next moderation position by repeating the operation, and even if there are variations in the strength of the operating force applied to the control lever, moderation can be reliably stopped at the required position, and furthermore, the operation lever can be moved to the next moderation position. To provide a moderation mechanism for an operating lever that allows a person to safely move the operating lever to a desired position without shifting his or her line of sight to the lever by counting the number of interferences when operating the lever. It is something.

The present invention will be described below with reference to embodiments shown in the drawings. The operating lever device of the present invention, as shown in FIG. 1, is provided on a guide plate 13 disposed at the front of the vehicle interior for operating an air conditioner for an automobile. An enlarged version of the lever device in FIG. 1 is shown in FIG. 2, and its disassembled state is shown in FIG. As shown in FIGS. 2 and 4, the operating lever is composed of metal plates 1 and 2 as main parts. plate 1 is plate 2
The end of the plate 1 is connected to the plate 2 via an elastic member 4 made of a metal spring wire to prevent relative movement. Resilience is always working. Further, the rotation range of the plate 1 is limited by a cut-and-raised portion 11 that is integral with the plate 2.

A plastic knob 10 is provided at the end of the plate 1. Meanwhile, the plate 2 is connected to a temperature control damper of an automobile air conditioner through a control cable connected to a multi-stage switch or variable resistor (not shown). A plastic slider 6 is fixed to the end of the plate 2 through an elastic member 5 made of a leaf spring. The slider 6 has a protrusion 12 cut and raised integrally from the plate 1 in an L-shape and a convex portion 1 provided on the slider 6.
The operating lever is lifted up by forming a cam device that allows interference between the movable member 5 and the movable member 6, and is set in the positional relationship shown in Fig. 3. A movable member 3 that can move within a guide groove 14 provided in a guide plate 13 of the operating lever is attached, and a plurality of protrusions 7 are provided at positions that interfere with protrusions 16 provided on the movable member 6 of the operating lever, and the movable member 6 is attached so that interference with the protrusions 7 of the movable member 3 is released when the movable member 6 is lifted up.

Further, the end of the mover 3 is connected to the guide groove 14 by a spring 9, and is set to move in the direction in which force is applied to the protrusion 7. Mover 3
An arbitrary number of protrusions 7 are provided at positions requiring moderation. Each of the above constituent members is the fourth
The assembly relationship is as shown in the figure.

The operation of the moderation mechanism of the operating lever configured as described above will be explained with reference to FIGS. 5a to 5f. Fig. 5a shows the normal state, and when an operating force is applied to the knob 10 and it is moved to the right, the knob 10 moves due to interference between the protrusion 16 of the slider 6 and the protrusion 7 of the slider 3, as shown in Fig. 5b. Child 3 is pushed to the right and compresses spring 9.
When the slider 3 moves fully to the right in the guide groove 14, the operating force is applied to the elastic member 4, causing it to rotate around the shaft 8. As the operating force continues to be applied, the protrusion 12 pushes down the protrusion 15 a little as shown in FIG. 5c, and comes to the right side of the protrusion 15 as shown in FIG. 5d. At this position,
Plate 1 corresponds to cut and raised portion 11 of plate 2.
Then, when the operating lever stops moving even when force is applied, the operating force that has been applied is removed, and the restoring force of the elastic member 4 causes the protrusion 12 to move from the protrusion of the slider 6 as shown in FIG. 5e. It moves along the lower surface of the section 15, and a force that lifts the mover 6 is exerted. Then, when the interference relationship between the protrusion 16 and the protrusion 7 is released, the slider 3 returns to its original position by the force of the spring 9 due to compression, as shown in Figure 5f, and as a result, the protrusion 7 Come to the left of 16. In other words, the interfering relationship between the protrusion 7 and the protrusion 16 is released, and if further operating force is applied, the lever moves to the right. In this way, even if a leftward force is applied to the knob 10, the same operation as described above can be achieved.

In the above embodiment, the mover 6 and the elastic member 5 are made of different materials, but the mover 6 may be integrally formed at the end of the elastic member 5 as shown in FIG. .

Further, as shown in FIG. 7, the attachment part of the elastic member 4 in the plate 1 is made into an elongated hole 19, and the part of the plate 2 into which the shaft 8 fixed to the elastic member 5 is inserted is made into an elongated hole 19. A guide 17 for preventing the elastic member 5 from rotating.
If the plate 1 is fixed by the cut-and-raised part 11 of the plate 2 in the state shown in FIG. It is also possible to adopt a configuration in which lever operation similar to that of the above embodiment is enabled by pulling the knob 10.

As described above, the present invention has an operating lever that has two plates, one of which is rotatable about the pivot axis within a limited range relative to the other, and the movement of this one plate. a first elastic member that acts to return the one plate to its original position against the rotational force; a protrusion that protrudes from the rotating surface of the one plate; and a protrusion of the protrusion relative to the other plate. A mover having a first protrusion that is provided to be able to move elastically in a direction, a plurality of second protrusions that interfere with the first protrusion, and a mover that resists movement of the mover. a second elastic member which acts to return the plate to its original position; and a second elastic member which engages with the protrusion when the one plate is rotated, is inclined with respect to the protrusion direction and has a predetermined length; Since the configuration is such that a convex part is provided integrally with the first protrusion, if this protrusion is provided at a place where the guide plate is to be moderated, the operating force will be too large and the lever will not be pushed at the desired position. This eliminates the need to return the lever and make corrections due to failure to stop, and the driver can count the number of times these protrusions interfere by feel.
It has the excellent effect of making it safer to operate the lever while driving a car because it can be operated without shifting one's line of sight toward the lever.
