Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a link stopper structure in which a link member connected to a wind direction switching door or the like of a vehicle air conditioner is temporarily fixed to a case of the air conditioner by a stopper member.

[0002]

2. Description of the Related Art Conventionally, as a link stopper structure of this kind, as disclosed in, for example, Japanese Utility Model Application Laid-Open No. 4-95511, a predetermined position of a link member arranged so as to overlap an outer surface of a case of an air conditioner is known. By providing a key hole, inserting a key piece (stopper member) into the key hole from a direction substantially orthogonal to the outer surface of the case, further inserting the key piece into the engaging portion provided on the outer surface of the case, and twisting by approximately 180 degrees, It is known that a key piece and an engaging portion are engaged with each other so that they can be securely fixed so as not to fall off.

In Japanese Patent Laid-Open No. 5-127769, a link member is arranged so as to overlap the outer surface of the case of an air conditioner as described above, and is substantially orthogonal to an insertion hole provided on the outer surface of the case. In the link fixing device in which the fixing pin is inserted from the direction to position the link member, both the insertion hole and the fixing pin have an oval cross section, and the fixing pin is aligned with the insertion part. And then twist it about 180 degrees,
A technique for reducing rattling and improving positioning accuracy is disclosed.

[0004]

By the way, in general,
Air conditioners for vehicles are installed inside the instrument panel in the front of the passenger compartment, but in recent years, airbags have become standard equipment inside the instrument panel. The mounting of in-vehicle electrical components such as audio and navigation systems is increasing, and the space is becoming very small.

For this reason, the gap between the air conditioner and other mounted equipment is extremely narrowed, and the air conditioner itself is required to reduce the space between the units as much as possible. As in the example, it becomes impossible to insert and remove stopper members such as key pieces and fixing pins from the direction orthogonal to the outer surface of the case of the air conditioner, and moreover, the operator inserts his hand into such a narrow space. Even twisting the stopper member is an extremely difficult task.

The present invention has been made in view of the above problems, and an object thereof is to temporarily fix a link member arranged on the outer surface of a case of a vehicle air conditioner by a stopper member. By carefully devising the structure of the part that fits with the stopper member in the link member and the case, it is possible to reduce the rattling of the stopper member and prevent the stopper member from falling off, and easily attach and detach the stopper member even in a narrow space. Is to be able to.

[0007]

In order to achieve the above object, according to a link stopper structure for a vehicle air conditioner according to the present invention, a projecting portion projecting from an outer surface of a case of the air conditioning system and a link facing the projecting portion. The member is provided with a groove portion extending in a preset direction along the outer surface of the case, and the stopper member is fitted into the groove portion.

Specifically, according to the invention of claim 1, a door member for adjusting the direction of the flow of the air for air conditioning is provided in the case of the air conditioner for a vehicle, and a link member for opening and closing the door member. Is provided on the outer surface of the case, and is premised on the link stopper structure of the vehicle air conditioner in which the link member is temporarily fixed to the fixed portion on the outer surface of the case at a predetermined position by the stopper member. The fixed portion of the case is formed with a projecting portion projecting from the outer surface of the case, a groove portion that is open to the projecting end surface and linearly extends in a set direction along the outer surface of the case, and one end portion of which is open to the outer peripheral surface of the projecting portion. On the other hand, the link member is provided with a groove portion that opens so as to correspond to the groove portion of the case when the link member is at the predetermined position, and further, the stopper member is provided in the setting direction. Along with this, there are provided two fitting portions that are respectively fitted into the groove portions of the link member and the case, and a claw portion that can be engaged and disengaged with the locking portion provided on the link member or the case.

With the above structure, when the link member is temporarily fixed at the predetermined position, the groove portion of the link member and the groove portion of the projecting portion of the case are aligned so as to face each other, and the stopper member is set in the setting direction with respect to these groove portions. The fitting portion is fitted, whereby the claw portion of the stopper member is locked and fixed by the link member or the locking portion of the case. As a result, the stopper member is prevented from falling off, and rattling can be sufficiently reduced by increasing the dimensional accuracy of the fitting portion and the groove portion of the stopper member.

On the other hand, when the temporary fixing of the link member is released, the stopper member is pulled in the set direction with a certain amount of force or more, so that the locking of the claw portion is released and the stopper member is pulled out from the groove portion. That is, even if the space between the case outer surface of the air conditioner in which the link member is disposed and the equipment adjacent to the case is very small, the stopper member can be easily removed along the space. The direction of the groove may be set so that the stopper member can be most easily pulled out depending on the shape of the boss or the like protruding to the outer surface of the case and the distance between the adjacent device.

According to the second aspect of the invention, the outer surface of the case in which the link member is disposed is substantially orthogonal to the vehicle width direction of the vehicle when the air conditioner is mounted on the vehicle. As a result, the direction in which the stopper member is pulled out (setting direction)
Since the direction is substantially perpendicular to the vehicle width direction, the stopper member can be easily removed from the gap between the adjacent devices even when the air conditioner is mounted inside the instrument panel of the vehicle.

According to the third aspect of the invention, the stopper member has two
In the middle of the two fitting portions, the stopper member extends outward from both sides in the thickness direction, and is sandwiched between the projecting end surface of the projecting portion of the case and the facing surface of the link member that faces the surface in close proximity. A clamped part shall be provided.

As a result, when the fitting portion of the stopper member is fitted into the projecting portion of the case and the groove portion of the link member, the sandwiched portion of the stopper member is sandwiched between the projecting end surface of the projecting portion and the facing surface of the link member. Since the will be pinched, rattling will be further reduced and the positioning accuracy will be improved.

According to the fourth aspect of the invention, the stopper member is a resin molded product, and the side surface on one side in the thickness direction of the fitting portion is in contact with the inner side surface on one side in each groove of the link member or the case. On the other hand, a plurality of ridges are formed on the opposite side surface so as to intersect with the inner surface on the other side of each groove so as to intersect with each other.

As a result, the clearance between the fitting portion of the stopper member and the groove portion can be made sufficiently small, and rattling can be minimized. That is, in general, as the resin molded product has a larger wall thickness, the sink mark at the time of molding becomes larger and the size thereof varies, which makes it difficult to maintain the required dimensional accuracy. If the thickness of the fitting portion of the member is simply set so as to correspond to the width of the groove portion, large rattling may occur due to dimensional deviation, or fitting may become too tight.

On the other hand, according to the present invention, in the fitting portion of the resin stopper member, the entire side surface on one side in the thickness direction is the contact surface with the groove portion, while a plurality of ridge portions are formed on the opposite side. Accordingly, while the dimension of the fitting portion in the thickness direction corresponds to the width of the groove portion, it is possible to reduce the wall thickness itself and suppress the dimension deviation. Moreover, since the plurality of ridges are provided so as to intersect with each other, the contact state between the ridges and the inner side surface of the groove becomes stable, which also causes rattling. Can be reduced.

On the other hand, when the fixation of the second link member 27 by the stopper member 37 is released, the grip portion 46 on the proximal end side of the stopper member 37 is grasped and pulled downward with a certain amount of force or more, and the claw portion is formed. The locked state of 43 is released, and the stopper member 37 is pulled out from the groove portions 36b and 40b. Therefore, even if the space between the blower unit 3 in which the link mechanism 25 is arranged and the air conditioning unit 2 is very narrow, the operator puts one hand in the space between the units 2 and 3 and Since it suffices to pull out the stopper member 37 along the line, the work can be performed very easily.

In the above-described embodiment, the air-conditioning unit 2 and the air-blowing unit 3 of the air-conditioning apparatus 1 are provided close to each other, and the link mechanism 25 of the present invention is used for the link mechanism 25 arranged in the gap between them. However, the present invention is not limited to this, and, for example, a link mechanism may be provided on the left side surface of the vehicle body of the blower unit 3 and the configuration of the present invention may be applied to the link mechanism. That is, when a mounted device such as a glove box or a CD changer is disposed near the left side surface of the vehicle body of the blower unit 3, the stopper member can be easily attached and detached even in a narrow space. Will be effective.

Needless to say, the link stopper structure according to the present invention can be applied not only to the link mechanism arranged in the case 19 of the blower unit 3 but also to the link mechanism on the air conditioning unit 2 side. .

[0052]

As described above, according to the link stopper structure of the vehicle air conditioner according to the invention of claim 1,
When the link member disposed on the outer surface of the case of the air conditioner is temporarily fixed at a predetermined position by the stopper member, the protrusion protruding from the outer surface of the case and the link member facing the protrusion are set in advance along the outer surface of the case. Since the groove portion extending in this direction is provided and the fitting portion of the stopper member is fitted into the groove portion, the distance between the outer surface of the case of the air conditioner in which the link member is disposed and the equipment adjacent to it is extremely small. Even if it is narrow, the stopper member can be easily attached or detached along the gap. Further, by locking the claw portion of the stopper member with the link member or the locking portion of the case, the stopper member can be prevented from falling off.

According to the second aspect of the present invention, with the air conditioner installed in the instrument panel of the vehicle, the stopper member is inserted / removed in a direction substantially orthogonal to the vehicle width direction so that the stopper members are adjacent in the vehicle width direction. The stopper member can be easily attached and detached from the gap between the fitting devices.

According to the third aspect of the present invention, the clamped portion provided between the two fitting portions of the stopper member is clamped between the case-side fixed portion and the link member to further reduce rattling. The positioning accuracy can be improved.

According to the fourth aspect of the present invention, one side surface in the thickness direction of the fitting portion of the stopper member serves as an abutting surface for abutting against the inner side surface of the groove portion, while a plurality of ridge portions intersecting each other are formed on the opposite side. By doing so, while setting a required dimension corresponding to the width of the groove portion in the thickness direction of the fitting portion, the wall thickness of the fitting portion itself can be made relatively thin, and the deviation of the dimension at the time of molding can be suppressed. . Therefore, rattling can be reduced and the positioning accuracy can be improved.
