Description

  The present invention relates to an air vortex launcher including a first air gun and a second air gun.

  2. Description of the Related Art A supply device has been proposed in which a fragrance component is supplied from a blowout port of an air conditioner mounted on a vehicle so as to keep the environment in the vehicle interior favorable. However, if the fragrance component is supplied from the outlet, the fragrance component diffuses throughout the passenger compartment, so that a large amount of the fragrance component is necessary to obtain a predetermined effect. In view of this, a supply device has been proposed in which an air cannon that can emit an air vortex is mounted so that an aroma component is included locally in the air vortex (for example, Patent Document 1 and 2).

Moreover, as shown in Patent Document 1, if an air vortex containing a fragrance component is fired so as to hit the user, there is a risk that the user may feel uncomfortable due to wind pressure. Therefore, as shown in Patent Document 2, by mounting a plurality of air cannons on the supply device, air vortices launched from the respective air cannons collide with each other to diffuse the fragrance component, A supply device has been proposed in which an aroma component is supplied without giving a sense of incongruity.

  By the way, since the supply apparatus described in patent document 2 is a structure which attaches an electric motor to each air cannon, the enlargement and cost increase of a supply apparatus provided with a plurality of air cannons are caused. It was. In particular, when a supply device is mounted on an instrument panel in a vehicle compartment, since a large number of devices are incorporated in the instrument panel, it has been desired to reduce the size of the supply device. In order to reduce the size and cost of the supply device, it may be possible to share a drive system for multiple air cannons. However, the air cannons should be installed in an inclined state to collide with air vortices. Therefore, it has been difficult to share the drive system.

  An object of the present invention is to achieve downsizing and cost reduction of an air vortex launcher including a first air gun and a second air gun.

  An air vortex launching device of the present invention includes an air chamber and a launch port communicating with the air chamber, a first air cannon that fires an air vortex by changing the volume of the air chamber, and an air chamber communicating with the air chamber. A second air cannon having a mouth and changing the volume of the air chamber to emit an air vortex; a forward position provided in the first air cannon for reducing the air chamber; and a retreat for expanding the air chamber A first rod that is movable to a position; a second rod that is provided on the second air cannon and is movable to a forward position for reducing the air chamber and a backward position for expanding the air chamber; A first cam that moves the first rod to a forward position and a backward position, and a rotary center that is tilted with respect to the second rod; Move the second rod to the forward and backward positions A second cam that, the first cam and the second cam is fixed, and having a cam shaft rotated by a driving means.

  In the air vortex launcher of the present invention, the sliding surface formed on the cam is a curved surface.

  The air vortex launcher of the present invention is characterized in that the sliding surface formed on the rod is an inclined surface inclined with respect to the traveling direction of the rod.

  An air vortex launcher according to the present invention includes a leaf spring member that biases the rod toward a forward position, a switch that outputs a signal when the leaf spring member is deformed to exceed a predetermined value, Recognizing means for recognizing the operating state of the air gun based on the signal.

  The air vortex launcher of the present invention includes a leaf spring member that urges the rod toward the forward position, a contact point that contacts the leaf spring member when the leaf spring member is deformed to exceed a predetermined value, Recognizing means for recognizing the operating state of the air gun based on the energized state of the leaf spring member in contact with the contact.

  According to the present invention, the first cam assembled with the rotation center inclined with respect to the first rod and the second cam assembled with the rotation center inclined with respect to the second rod are arranged with respect to the cam shaft. I try to fix it. As a result, the drive system of the air cannon that is installed at an inclination can be easily configured, and the air vortex launcher can be reduced in size and cost.

  Further, since the first cam and the second cam are fixed with respect to one cam shaft, it is possible to combine the driving means for rotationally driving the first cam and the second cam into one. . This makes it possible to further reduce the size and cost of the air vortex launcher.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view showing a vehicle equipped with an air vortex launcher 10 (hereinafter referred to as launcher) according to an embodiment of the present invention. As shown in FIG. 1, a launching device 10 installed in an instrument panel 11 in a passenger compartment includes a first air cannon 12 that launches an air vortex ring (air vortex) V <b> 1 containing an aromatic component, and air containing an aromatic component. And a second air gun 13 for firing a vortex ring (air vortex) V2. These air cannons 12 and 13 are installed in an inclined state, and the vortex rings V1 and V2 can be fired toward the diffusion region B set at the nose tip of the occupant A. Accordingly, the vortex rings V1 and V2 can be made to collide with each other in the diffusion region B to cancel each other, and the fragrance component can be supplied to the occupant A without feeling uncomfortable due to the wind pressure.

  FIGS. 2A to 2D are explanatory views showing a procedure for launching the vortex rings V1 and V2 by the air cannons 12 and 13. FIG. As shown in FIG. 2 (A), each of the air cannons 12 and 13 has sleeves 14 and 15 for partitioning air chambers 14a and 15a on the inner side. End plates 16 and 17 having 16a and 17a are provided, and pistons 18 and 19 are slidably assembled to the other ends of the sleeves 14 and 15, respectively. The rods 20 and 21 connected to the pistons 18 and 19 are formed with cam holes 22 and 23 having protrusions 22a and 23a. The protrusions 24a and 23 are formed in the cam holes 22 and 23, respectively. Cams 24 and 25 having 25a are slidably assembled. Further, coil spring members 26 and 27 are assembled at the rear ends of the rods 20 and 21, and the rods 20 and 21 are urged toward the advance position by the coil spring members 26 and 27.

  When the vortex rings V1 and V2 are fired from the air cannons 12 and 13, the cam springs 26 and 27 are rotated by rotating the cams 24 and 25, as shown in FIGS. 2, the rods 20 and 21 are moved from the advanced position to the retracted position, and then the compressed state of the coil spring members 26 and 27 is released to move the rods 20 and 21 to the retracted position, as shown in FIG. It is made to move instantaneously from the forward position to the forward position. In this way, by moving the rods 20 and 21 from the retracted position where the air chambers 14a and 15a are expanded toward the advanced position where the air chambers 14a and 15a are contracted, the volume of the air chambers 14a and 15a is instantaneously reduced. Therefore, the vortex rings V1 and V2 can be fired from the launch ports 16a and 17a. In addition, the air chambers 14a and 15a in the air cannons 12 and 13 are supplied with fragrance components from fragrance units 36 and 37, which will be described later, and can be included in the vortex rings V1 and V2 to be launched. It has become.

  FIG. 3 is a schematic diagram showing the configuration of the launching device 10. As shown in FIG. 3, in order to output a drive signal to each drive unit of the launching device 10, the launching device 10 is provided with a control unit 30. The control unit 30 includes a microprocessor (CPU) (not shown), and a ROM, a RAM, and an I / O port are connected to the CPU via a bus line. The ROM stores control programs and various map data, and the RAM temporarily stores data calculated by the CPU. The control unit 30 is connected to an operation switch 31 that is operated by an occupant, and the control unit 30 controls the type of fragrance component, the firing timing of the vortex rings V1 and V2, and the like based on the switch operation of the occupant. Become.

  In addition, the launching device 10 is provided with an electric motor 32 as a driving means for operating the air cannons 12 and 13, and a cam shaft 34 that is driven by the electric motor 32 via a reduction gear train 33. ing. A first cam 24 for driving and controlling the air cannon 12 is fixed to one end of the cam shaft 34, and a second cam 25 for driving and controlling the air cannon 13 is fixed to the other end of the cam shaft 34. Yes. 4 is a perspective view showing the shapes of the cams 24 and 25, and FIGS. 5A to 5D are explanatory views showing the operating states of the cams 24 and 25. FIG. As shown in FIG. 4, the sliding surfaces 24b and 25b of the cams 24 and 25 are curved surfaces, and the rotation centers (cam shafts) of the cams 24 and 25 are shown in FIGS. 34 axial direction) and the traveling direction of the rods 20, 21 can be inclined with respect to each other. Thus, by curving the sliding surfaces 24b and 25b of the cams 24 and 25, the angular difference between the cam shaft 34 and the rods 20 and 21 can be absorbed, so that one cam shaft 34 is rotated. Thus, the two rods 20 and 21 having different installation angles can be moved between the forward position and the backward position.

  A rotation sensor 35 for detecting the rotation position of the driven gear 33 a is provided in the vicinity of the driven gear 33 a fixed to the camshaft 34, and a rotation signal is output from the rotation sensor 35 to the control unit 30. Has been. The control unit 30 functioning as a recognition means recognizes the operating state of the air gun based on the position signals of the cams 24 and 25 output from the rotation sensor 35 and drives the electric motor 32 based on the recognized operating state. The signal is controlled. Further, the air cannons 12 and 13 are provided with fragrance units 36 and 37 each having a porous body such as ceramic impregnated with an fragrance component, and the fragrance components diffusing from the fragrance units 36 and 37 are air cannons.

As described above, even when the pair of air cannons 12 and 13 are inclined with respect to each other, that is, when the pair of rods 20 and 21 are inclined with respect to each other, the sliding of the cams 24 and 25 assembled to the rods 20 and 21 is performed. Since the surfaces 24b and 25b are curved, the rotation center of the cams 24 and 25 and the traveling direction of the rods 20 and 21 can be inclined. Thereby, since the two rods 20 and 21 having different operating directions can be driven by the single camshaft 34, the drive system of the air cannons 12 and 13 can be combined into one, and the launching device 10 It is possible to achieve downsizing and cost reduction. Further, by combining the drive systems, the operation state of the individual air cannons 12 and 13 can be recognized by one rotation sensor 35, so that the control system can be simplified.

  In the above description, the sliding surfaces 24b and 25b of the cams 24 and 25 are curved surfaces in order to incline the rotation center of the cams 24 and 25 and the moving direction of the rods 20 and 21, but this is not limited thereto. However, a flat sliding surface with respect to the cam may be formed. Here, FIG. 6 is a perspective view showing the shapes of the cams 41 and 42 incorporated in the launching apparatus according to another embodiment of the present invention, and FIGS.

As shown in FIG. 6, even when the sliding surfaces 41a and 42a of the cams 41 and 42 are formed flat, they are formed on the rods 20 and 21 as shown in FIGS. By configuring the sliding surfaces 43a, 44a of the cam holes 43, 44 as inclined surfaces that are inclined with respect to the traveling direction of the rods 20, 21, the rotation centers of the cams 41, 42 (the axial direction of the cam shaft 34) And the traveling directions of the rods 20 and 21 can be inclined with respect to each other. Thereby, since the two rods 20 and 21 having different operating directions can be driven by the single camshaft 34, the drive system of the air cannons 12 and 13 can be combined into one, It is possible to achieve downsizing and cost reduction.

  In the above description, in order to push the rods 20 and 21 from the retracted position to the advanced position, the coil spring members 26 and 27 are provided for the individual rods 20 and 21, but a plate spring member is used. The rods 20 and 21 may be pushed out. Here, FIG. 8 is a schematic view showing a configuration of a launching apparatus 50 according to another embodiment of the present invention.

The detection signal from the proximity switch 52 is output toward the control unit 30 functioning as a recognition unit, and the control unit 30 recognizes the operating state of the air gun based on the detection signal. As described above, when the leaf spring member 51 is used, the operation state of the air cannon can be recognized by the simple proximity switch 52, and thus the cost of the launching device 50 can be reduced. Further, by using the leaf spring member 51, both the rods 20 and 21 can be pushed out by one leaf spring member 51, and the cost of the launching device 50 can be reduced by reducing the number of parts. Become.

  In the case shown in FIG. 8, the operation state of the air cannon is recognized by the proximity switch 52 disposed in the vicinity of the leaf spring member 51, but the leaf spring member 51 may function as a switch. .
