Description

Air conditioner

Technical Field

The present disclosure relates to an air conditioner.

Background

An air conditioner provided with a fan for supplying air to a seat cushion or discharging air from the seat cushion may be provided in a vehicle seat disposed in a vehicle or the like. The air conditioner is mounted on a seat cushion frame that supports a seat cushion (see japanese patent No. 6623844).

A component holder for holding a wire harness connected to an air conditioner and other devices is arranged below the air conditioner. Therefore, when the load of the seat cushion increases due to the sitting of the user, or when the seat cushion is lowered by the lifting device, or the like, the fan may interfere with the member holder.

Here, it is conceivable to suppress interference between the fan and the component holder by providing a stopper on the air conditioner that contacts the component holder from above.

Disclosure of Invention

The position and shape of the retainer are different depending on the specification of the vehicle seat (for example, the position of the vehicle seat in the vehicle), and therefore it is necessary to change the position and shape of the stopper in accordance with the vehicle seat. As a result, the cost of the air conditioner increases.

An aspect of the present disclosure preferably provides an air conditioning apparatus capable of generalizing a shape of a casing for suppressing interference between the casing and a component holder.

One aspect of the present disclosure relates to an air conditioner for use in a vehicle seat including a cushion frame and a member holder disposed below the cushion frame. The air conditioner includes a fan and a housing for holding the fan.

The housing has a housing main body, a 1 st stopper, and a 2 nd stopper, the housing main body is configured to hold the fan and is attached to the cushion frame; a 1 st stopper projecting downward from the housing main body and configured to restrict downward movement of the housing at a position opposed to the member holder; the 2 nd stopper protrudes downward from the housing main body at a position different from the 1 st stopper, and is configured to restrict downward movement of the housing at a position facing the member holder.

According to the above configuration, interference of the housing with the component holders having different shapes can be suppressed by providing the housing with the plurality of stoppers arranged at staggered positions. That is, the shape of the housing can be made common to the vehicle seat having the member holders having different shapes. Therefore, the cost of the air conditioner can be reduced.

In one aspect of the present disclosure, a lower end of the 2 nd stopper may be located at a lower position than a lower end of the 1 st stopper. According to the above configuration, the shape of the housing can be easily made common to the plurality of component holders having different heights of portions facing the housing.

In one aspect of the present disclosure, the air conditioner may be used for a 1 st vehicle seat and a 2 nd vehicle seat, which have different shapes of the component holder from each other. The 1 st stopper may be configured to: the 1 st stopper is disposed at a position facing the member holder of the 1 st vehicle seat, thereby restricting downward movement of the housing. The 2 nd stopper may be configured to: the housing is restricted from moving downward by arranging the 2 nd stopper at a position facing the member holder of the 1 st vehicle seat, and the housing is restricted from moving downward by arranging the 2 nd stopper at a position facing the member holder of the 2 nd vehicle seat.

According to the above configuration, the movement of the housing can be restricted by the 1 st stopper in addition to the 2 nd stopper with respect to the housing whose movement can be restricted by the 1 st stopper. Therefore, the effect of suppressing the interference of the housing with the member holder can be promoted.

In one aspect of the present disclosure, the vehicle seat may further include a lifting device and/or a tilting device, and the lifting device and/or the tilting device may be configured to: at least a part of the seat cushion frame is moved in the up-down direction with respect to the member holder. According to the above configuration, when the seat cushion frame is lowered by the lifter and/or the recliner, interference of the housing with the member holder can be reliably suppressed.

The 1 st vehicle seat 100 is used as a seat of a passenger car. Note that the directions in the following description and the drawings indicate the directions in a state where the 1 st vehicle seat 100 is mounted in a vehicle (i.e., a passenger car). In the present embodiment, the seat width direction coincides with the left-right direction of the vehicle, and the seat front coincides with the front of the vehicle.

The seat cushion 101 is a part for supporting the buttocks of the seated person. The seat back 102 is a portion for supporting the back of a seated person. The seat cushion frame 103 supports the seat cushion 101.

< cushion frame >

As shown in fig. 2A and 2B, the seat cushion frame 103 has a left side frame 103A, a right side frame 103B, a front panel 103C, a 1 st link 103D, and a 2 nd link 103E.

The left side frame 103A and the right side frame 103B each extend in the front-rear direction and are disposed at a distance from each other in the seat width direction. The front panel 103C, the 1 st bar 103D, and the 2 nd bar 103E link the left side frame 103A and the right side frame 103B in the seat width direction.

The front panel 103C supports the front portion of the seat cushion 101 from below. The rear end portion of the front panel 103C is attached to the front end portions of the left and right side frames 103A and 103B via a tilt device 106.

The 1 st rod 103D and the 2 nd rod 103E are formed of cylindrical tubes. The 1 st lever 103D is disposed behind the front panel 103C. The 2 nd lever 103E is disposed rearward of the 1 st lever 103D.

< sliding device >

The 1 st slide device 104A and the 2 nd slide device 104B are configured to slide the seat cushion 101 and the seat back 102 in the seat front-rear direction in cooperation.

Each of the 1 st slide device 104A and the 2 nd slide device 104B has a movable rail attached to the seat cushion frame 103, and a fixed rail fixed to the floor surface of the vehicle and slidably supporting the movable rail.

The movable rail of the 1 st slide device 104A is attached to the left side frame 103A via the lifter 105. The movable rail of the 2 nd slide device 104B is attached to the right side frame 103B via the lifter device 105.

< lifting device >

The lifter 105 is configured to move the cushion frame 103 in the vertical direction with respect to the floor surface of the vehicle (i.e., the 1 st slide device 104A and the 2 nd slide device 104B).

The lifter device 105 includes a plurality of links that connect the movable rails of the left side frame 103A and the slide device 104A and connect the movable rails of the right side frame 103B and the slide device 104B, and a driving source such as a motor that drives the plurality of links.

< tilting apparatus >

The reclining device 106 vertically moves the front portion of the seat cushion 101 relative to the rear portion by swinging the front panel 103C relative to the left and right side frames 103A and 103B.

The reclining device 106 includes a plurality of links that connect the rear end portions of the left side frame 103A and the front panel 103C and the rear end portions of the right side frame 103B and the front panel 103C, and a driving source such as a motor that drives the plurality of links.

< component holder >

The member holder 107 holds a plurality of wire harnesses for supplying power from the vehicle to the

slide devices

104A, 104B, the lifting device 105, the tilting device 106, the air conditioner 1, and the like, or for performing communication between the devices and the vehicle.

The member holder 107 is disposed below the cushion frame 103. Specifically, the component holder 107 is disposed at a position that overlaps the front panel 103C in the up-down direction, among the lower side of the front panel 103C.

The member holder 107 is not fixed to the cushion frame 103. The member holder 107 is attached to the movable rail of the 1 st slide device 104A and the movable rail of the 2 nd slide device 104B by, for example, a bracket not shown. Therefore, the lifter 105 and the recliner 106 move the whole or part of the cushion frame 103 in the vertical direction with respect to the member holder 107.

< air conditioner >

The air conditioner 1 is a device for supplying air to the seat cushion 101 or discharging air from the seat cushion 101. The air conditioner 1 is mounted on the cushion frame 103.

As shown in fig. 3A and 3B, the air conditioner 1 includes a fan 2, a casing 3, and a duct 4.

(Fan)

The fan 2 is configured to perform an air blowing operation for sending air to the duct 4 or a ventilation operation for sucking air from the duct 4 by rotating a plurality of blades. In addition, the fan 2 may have a function of heating or cooling air by a heater or a cooler.

(outer cover)

The housing 3 has a housing main body 31, a 1 st stopper 32, a 2 nd stopper 33, and a connector 34.

The housing main body 31 includes a frame 31A, a projection 31B, and a locking portion 31C. The frame 31A holds the fan 2 by surrounding the fan 2. The protruding portion 31B protrudes forward from the frame 31A.

The locking portion 31C is a hook portion arranged above the frame 31A and having a C-shape. As shown in fig. 2B, the locking portion 31C is locked to the 1 st lever 103D of the seat cushion frame 103 from the front.

The locking portion 31C is not fixed to the 1 st lever 103D, but is locked to the 1 st lever 103D so as to be slidable on the outer peripheral surface of the 1 st lever 103D. Therefore, the housing main body 31 is attached to the seat cushion frame 103 so as to be swingable about the center axis of the 1 st lever 103D.

The housing 3 and the seat cushion frame 103 are moved together in the vertical direction relative to the member holder 107 by the lifter 105. Further, the housing 3 swings in the vertical direction as the front panel 103C swings in the vertical direction by the tilting device 106.

As shown in fig. 4, the 1 st stopper 32 and the 2 nd stopper 33 each protrude downward from the protruding portion 31B of the housing main body 31. The 2 nd stopper 33 protrudes from a position different from the 1 st stopper 32 in the protruding portion 31B (specifically, from the right side of the 1 st stopper 32). Further, the lower end of the 2 nd stopper 33 is located below the lower end of the 1 st stopper 32.

The 1 st stopper 32 and the 2 nd stopper 33 are both disposed at positions facing the member holder 107 in the vertical direction. Therefore, the 1 st stopper 32 and the 2 nd stopper 33 are both configured to restrict the downward movement of the housing 3 by contacting the member holder 107 from above.

Fig. 4 shows a state in which the housing 3 is at the lowermost position (i.e., the lowermost descending point) in the movement range in which the housing 3 is moved by the lifting device 105 and the tilting device 106. In this state, the 1 st stopper 32 and the 2 nd stopper 33 contact the member holder 107 from above together, and the housing 3 is restricted from moving downward.

Specifically, the lower surface of the 1 st stopper 32 and the lower surface of the 2 nd stopper 33 are in contact with the member holder 107 at different heights, respectively. Further, a portion of the housing 3 other than the 1 st stopper 32 and the 2 nd stopper 33 is spaced apart from the member holder 107.

When the housing 3 is located at the lowest lowering point, the 1 st stopper 32 and the 2 nd stopper 33 may not contact the member holder 107. The position of the seat cushion frame 103 in the up-down direction varies depending on the magnitude of the load (e.g., the weight of the seated person) applied to the seat cushion 101.

Therefore, it is also possible to design: when the load applied to the seat cushion 101 is the maximum load, the 1 st stopper 32 and the 2 nd stopper 33 are in contact with the member holder 107, and when less than the maximum load, gaps are generated between the 1 st stopper 32 and the 2 nd stopper 33 and the member holder 107.

In the present embodiment, the 1 st stopper 32 and the 2 nd stopper 33 are provided continuously (i.e., adjacently) in the seat width direction. The lower surfaces of the 1 st stopper 32 and the 2 nd stopper 33 are flat surfaces. The 1 st stopper 32 and the 2 nd stopper 33 are disposed on the left side of the center axis of the fan 2.

In the present embodiment, the 1 st stopper 32 and the 2 nd stopper 33 are formed integrally with the housing main body 31 by molding. However, the 1 st stopper 32 and the 2 nd stopper 33 may be configured as members that are attached to the housing main body 31 and are independent from the housing main body 31.

The connector 34 is a portion to which a wire harness for supplying power to the fan 2 and inputting a signal to the fan 2 is connected. The connector 34 is disposed below the frame 31A so that a terminal of the wire harness can be inserted into the connector 34 from the front.

In the present embodiment, the connector 34 is disposed on the right side of the 1 st stopper 32 and the 2 nd stopper 33. The connector 34 is disposed at a position overlapping the central axis of the fan 2 in the front-rear direction.

(guide tube)

The duct 4 shown in fig. 3A and 3B constitutes a flow path of air supplied by the fan 2 or air sucked by the fan 2.

The conduit 4 is a corrugated pipe body formed of an elastic body such as a flexible rubber. The lower end of the duct 4 is connected to the fan 2. The upper end of the duct 4 opens toward the seat cushion 101.

The pipe 4 has a coupling portion 41 projecting radially outward from an upper end portion of the pipe 4. The coupling portion 41 is provided with a hole through which a bolt is inserted. The duct 4 is attached to the front panel 103C via the coupling portion 41.

As the front panel 103C is swung in the vertical direction by the tilting device 106, the upper end portion of the duct 4 moves in the vertical direction. When the front panel 103C swings upward, the duct 4 is pulled upward and downward, and the fan 2 and the casing 3 connected to the duct 4 swing upward around the 1 st lever 103D. When the front panel 103C swings downward, the duct 4 contracts, and the fan 2 and the housing 3 swing downward around the 1 st lever 103D.

< seat for vehicle 2 >

As shown in fig. 5A and 5B, the air conditioner 1 may be mounted on the 2 nd vehicle seat 100A including the member holder 107A.

The 2 nd vehicle seat 100A is disposed, for example, in a different position from the 1 st vehicle seat 100 in the same vehicle. Therefore, the wiring path (i.e., wiring process) of the wire harness connected to the 2 nd vehicle seat 100A and the wiring path of the wire harness connected to the 1 st vehicle seat 100 are different. Thus, the member holder 107A of the 2 nd vehicle seat 100A and the member holder 107 of the 1 st vehicle seat 100 of fig. 1 have different shapes from each other.

The structure of the 2 nd vehicle seat 100A other than the component holder 107A is the same as that of the 1 st vehicle seat 100. The mounting position of the air conditioner 1 in the 2 nd vehicle seat 100A is also the same as that of the 1 st vehicle seat 100.

As shown in fig. 6, in the 2 nd vehicle seat 100A, the 1 st stopper 32 and the 2 nd stopper 33 of the air conditioner 1 are both disposed at positions that are opposed to the member holder 107A in the up-down direction.

In a state where the casing 3 of the air conditioner 1 is at the lowest descent point shown in fig. 6, the 2 nd stopper 33 contacts the member holder 107A from above, and the 1 st stopper 32 does not contact the member holder 107A.

That is, the 2 nd vehicle seat 100A is configured to: the housing 3 is restricted from moving downward by only the 2 nd stopper 33 of the 1 st stopper 32 and the 2 nd stopper 33 contacting the member holder 107A from above.

In other words, the 2 nd stopper 33 functions as follows: movement of the housing 3 is restricted in both the 1 st vehicle seat 100 and the 2 nd vehicle seat 100A. On the other hand, the 1 st stopper 32 functions as follows: the movement of the housing 3 is restricted only in the 1 st vehicle seat 100.

[1-2. Effect ]

According to the embodiments described in detail above, the following effects can be obtained.

(1a) By providing the 1 st stopper 32 and the 2 nd stopper 33 arranged at different positions in the housing 3, interference of the housing 3 with the

member holders

107, 107A having different shapes can be suppressed. That is, the shapes of the housings 3 can be made common to the vehicle seats 100 and 100A provided with the

member holders

107 and 107A having different shapes. Therefore, the cost of the air conditioner 1 can be reduced.

(1b) By positioning the lower end of the 2 nd stopper 33 below the lower end of the 1 st stopper 32, the shapes of the housings 3 can be made more versatile for the plurality of

component holders

107, 107A having different heights of portions facing the housings 3.

(1c) The 2 nd stopper 33 in the 1 st vehicle seat 100 restricts the movement of the housing 3 together with the 1 st stopper 32, and thus the movement of the housing 3 can be restricted by the 1 st stopper 32 in addition to the 2 nd stopper 33 with respect to the housing 3 whose movement can be restricted by the 1 st stopper 32. Therefore, the effect of suppressing the interference of the housing 3 with the member holder 107 can be promoted.

(1d) When the seat cushion frame 103 is lowered by the lifter 105 and/or the recliner 106, interference of the housing 3 with the

member holders

107, 107A can be reliably suppressed.
