Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a lever device for operating a vehicle air conditioner.

(Prior Art) An operating lever device used in a vehicle air conditioner consists of an operating lever made of a single bar or elongated member, one end of which is rotatably supported, and the other end of which is supported with a finger. A knob is provided for easy operation, a cable connecting member is provided protruding from the side of this operating lever, and the end of the cable is connected to the cable connecting member.

(Problem to be solved by the invention) In the conventional operating lever device having the above structure, the operating lever moves in an arc shape, so when the knob is located at both ends of the operating range, it retracts toward the back. This makes it difficult to grasp the knob, making it difficult to operate, and the amount of movement of the cable connected to the side of the operating lever relative to the amount of movement of the knob is caused by the discrepancy between the length of the arc and the length of the string. There was a problem that a discrepancy in the amount occurred.

The present invention provides an operating lever device that solves the above problems.

(Means for Solving the Problems) The present invention, as a means for solving the above problems, includes forming a base body with an upright display board mounting part and a substrate extending rearward from the lower end of the display board mounting part, A display board is attached to the front of the display board mounting part, a lever guide is attached to the back of the display board mounting part, a lever through hole is provided in alignment with the display board mounting part, the display board, and the lever guide, and a lever through hole is provided in the lever through hole. In the operating lever device configured to move the cable using a slide lever inserted through the board, a rotating member having a portion of which the cable is fixed is rotatably supported at the rear upper part of the board. , the other part of the rotating member is formed into a downwardly slanted bent part, a hole is provided in the slanted bent part, and the rear end of the slide lever having a tapered rear end is inserted into the hole; A part of the slide lever is also formed with a slope bent part with a hole, and the tip of the rotary member having a tapered tip is inserted into the hole, and by this insertion, it overlaps with the rotary member in surface contact. The fitted slide levers are connected so as to be slidable in the radial direction, and a torsion spring is stretched between the rotating member and the slide lever to bias the rotating member in a direction that increases the total length of the combination. A long hole is bored for relief of the torsion spring,
The front part of the slide lever from the sloped bent part is raised upward and then extended horizontally, and the horizontal part is inserted into the lever through hole to form a knob mounting part, and the lever guide is attached to the slide lever. A mode groove into which the guide pin fits is formed on the back surface of the linear lever guide.

(Function) With the above configuration, the slide lever, which is biased by a torsion spring in a direction away from the pivot point of the rotating member, moves the guide member to the lever guide disposed on the back surface of the lever through hole. Since the position of the slide lever is regulated by coming into contact with the lever guide, the slide lever is moved substantially in parallel according to the lever guide, and the amount of movement in the longitudinal direction is absorbed by the slide lever sliding relative to the rotating member. As a result, the amount of operation movement of the slide lever becomes substantially linear, and it is possible to avoid errors in the control amount, that is, deviations in the amount of movement, due to the operation end of the slide lever drawing an arc. Therefore, when the operating end portions of the slide lever are located at both ends of the operating range, it is possible to avoid being pulled inward. When the slide lever is operated, the guide pin fits into the mode groove, so a good sense of moderation can be obtained.

(Embodiments) Hereinafter, illustrated embodiments of the present invention will be described. 1 to 4 show the basic parts of the present invention, in which 1 is a base. This base body 1 consists of a horizontally provided substrate 2 and a display plate mounting portion 4 formed in a straight line with its front portion raised up in order to attach a display plate 3 thereto. A lever through hole 5 is bored in the center of the display board mounting portion 4, and a lever guide 6 is provided along the lever through hole 5 on the side opposite to the side where the display board 3 is mounted. ing.

A rotating member 7 is attached to a pin 8 at the end (rear end) opposite to the end where the display board mounting portion 4 is raised.
It is rotatably supported by. This rotating member 7 is formed of a plate material having a V-shaped planar shape, and has a hole 7 for inserting a pin at the base of the two forks.
A is bored through the hole 7a, and a pin 8 is inserted through the hole 7a. One end of a cable 9 is locked to one end of the V-shaped rotating member 7. The other end of the cable 7 is connected to a damper valve of an air conditioner (not shown). A slide lever 10 made of an elongated plate is slidably attached to the other side of the rotating member 7 by a structure described below.

A portion of the rotating member 7 is formed with a downwardly bent sloped portion, and a hole 14 is formed in this sloped bent portion.
is provided, and the rear end of the slide lever 10 having a tapered rear end is inserted into this hole 14. A part of the slide lever 10 is also formed with a sloped bent portion provided with a hole 15, into which the tip of the rotating member 7 having a tapered tip is inserted. By this insertion, the slide lever 10, which overlaps the rotating member 7 in surface contact, is coupled so as to be slidable in the radial direction.

A torsion spring 13 is stretched between the rotating member 7 and the slide lever 10 and biases the rotating member 7 and the slide lever 10 in a direction in which the total length of the combination becomes longer (a direction in which the slide lever 10 extends in the X direction in FIG. 3). The rotating member 7 is provided with a long hole 7b for allowing the torsion spring 13 to escape. The front part of the slide lever 10 from the inclined bent part is raised upward and then extended horizontally, and this horizontal part 10a is inserted into the lever through hole 5, and this part is formed as the mounting part of the knob 11. There is. A guide pin 12 that contacts the back surface of the lever guide 6 is attached to the slide lever 10.

5 and 6 show the guide pin 12 and mode groove 16 in addition to the parts shown in FIGS. 1 to 4. FIG. As shown in these figures, a mode groove 16 defining a specific control position is carved in the abutting end surface of the guide pin 12 of the lever guide 6. As a result, knob 11
When the guide pin 12 reaches the position where the mode groove 16 is carved during the operation, the slide lever 10 is slid against the rotating member 7 by the elastic force of the torsion spring 13, and the guide pin 12 is inserted into the mode groove 16. When inserted, a click mechanism is formed that conveys a sense of moderation to the fingers when operating the knob 11.

In this operating lever device configured in this way, the slide lever 10 is biased in the direction away from the pin 8 (X direction in FIG. 3) by the elastic force of the torsion spring 13, so that the guide pin 12 will always come into contact with the end surface of the lever guide 6. In this state, when you pinch the knob 11 with your fingers and move it in the left-right direction, the guide pin 12 moves in the direction of movement of the knob 11 while coming into contact with the end surface of the lever guide 6, and the mode grooves 1 provided at several locations move.
6, it fits into the mode groove 16.

The slide lever 10 can be easily selected and stopped at any position by aligning the location where the mode groove 16 is provided with the wind outlet position shown in FIG. 4 (the locations indicated by A to D in FIG. 6). become. When the knob 11 is moved, the slide lever 10 and the rotating member 7 rotate together around the pin 8, so the cable 9 moves, thereby opening and closing the damper valve of the air conditioner (not shown). operations will be performed.

When operating in this manner, the rotating member 7 and the slide lever 10 are biased by the torsion spring 13 in a direction that increases the total length of their combined length, so that the rotating member 7 and the slide lever 10 are centered around the pin 8. The length error caused by the difference between the rotation and the movement of the guide pin 12 is corrected, the deviation between them is absorbed, and the operation can be controlled accurately.

(Effects of the invention) Since the present invention is an operating lever device configured as described above, the knob can be moved linearly by the coupling structure of the rotating member and the slide lever, and the rotation for this purpose is The movable member and the slide lever can be smoothly extended and contracted. Even though it can expand and contract smoothly in this way, the connection structure is such that one end with a thin end is inserted into the hole of the other, so the connection is strong and the rotational force is reduced. Even if you join, you will not be affected by it. The rotating member and the slide lever come into surface contact, and this part has a flat overlapping structure, resulting in a small and simple structure. A torsion spring stretched between the rotating member and the slide lever can also serve as a moderation spring that determines the stop position of the knob.
