[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, modes for carrying out the present invention (hereinafter, referred to as "embodiments") will be described in detail with reference to the accompanying drawings. In addition, the same elements are designated by the same numbers throughout the description of the embodiments. The hole portion to be engaged is referred to as an engaging hole portion, and the projection to be engaged is referred to as an engaging projection.
[0012] FIG. 1 is a perspective view of a rotating device 10 according to an embodiment of the present invention, FIG. 2 is a perspective view of the rotating device 10 with a first housing 23 removed, and FIG. As shown in FIG. 1, the rotating device 10 has a housing 20 formed by combining a first housing 23 having a first surface portion 21 as a surface portion and a first side wall portion 22 provided on the outer periphery of the first surface portion 21, and a second housing 27 having a second surface portion 25 as a surface portion and a second side wall portion 26 provided on the outer periphery of the second surface portion 25. The housing 20 is made of a resin material such as polypropylene, polyethylene terephthalate, or ABS.
[0013] As shown in FIG. 3, the first housing 23 has engagement portions 22b formed integrally with the first side wall portion 22, the engagement portions 22b extending toward the second housing 27 and provided on the outer periphery of the first side wall portion 22, and engagement holes 22a are provided in the engagement portions 22b.
[0014] In addition, as shown in Figure 3, the second housing 27 has a plurality of engagement protrusions 26a that engage with the engagement holes 22a of the engagement portions 22b at positions on the outer periphery of the second side wall portion 26 corresponding to each of the plurality of engagement portions 22b of the first housing 23, and are formed integrally with the second side wall portion 26.
[0015] Then, by combining the first housing 23 and the second housing 27 so that the engagement protrusion 26a of the second housing 27 engages with the engagement hole 22a of the engagement portion 22b of the first housing 23, the first housing 23 and the second housing 27 are integrated to form a housing 20 (see Figure 1) that houses various parts shown in Figures 2 and 3.
[0016] In this embodiment, an engagement portion 22b having an engagement hole 22a is provided on the first housing 23, and an engagement protrusion 26a is provided on the second housing 27, but it is also possible to provide an engagement portion on the second housing 27 and provide an engagement protrusion on the first housing 23.
[0017] As shown in FIG. 3, the outer periphery of the first housing 23 is provided with mounting portions A, B, C, and D for mounting the rotating device 10 to an air conditioning system.
[0018] The rotating device 10 includes various parts housed within a housing 20 (see FIG. 1), as shown in FIGS. 2 and 3, including a motor 30, a plurality of gears 60 including an output gear 50 that mechanically outputs the rotation of a rotating shaft 32 (see FIG. 3) of the motor 30 to the outside, and a sensor 70 that detects the rotation angle of the output gear 50. Further, the second housing 27 is provided with an opening 25a in a portion corresponding to the center side of the output gear 50, as shown in FIG.
[0019] FIG. 4 is a perspective view showing the second face portion 25 side of the second housing 27 of the rotating device 10. As shown in FIG. As shown in FIG. 4, the engagement portion 51 of the output gear 50 can be accessed from the outside through an opening 25a provided in the second surface portion 25 of the second housing 27, so that, for example, the drive shaft of a louver of an air conditioning system provided in a vehicle such as an automobile (not shown) can engage with the engagement portion 51 of the output gear 50.
[0020] Therefore, by rotating the output gear 50, a louver (not shown) provided in the air passage (hereinafter also referred to as the air flow path) of the air conditioning system is controlled, for example, so that the air passage of the air conditioning system is controlled to a predetermined opening degree.
[0021] (Motor) The motor 30 is a drive device for rotating the output gear 50, and in this embodiment, a DC motor is used. As shown in FIG. 3, the motor 30 includes a main body 31 having a rectangular prism-like shape with curved corners, a rotating shaft 32 extending from a first end face 31a of the main body 31, and a pair of motor terminals 33 located on the opposite side of the first end face 31a of the main body 31 and protruding outward from a second end face 31b facing the first end face 31a. The rotating shaft 32 is fixed to a rotor housed in the main body 31 of the motor 30 .
[0022] (Transmission gear) As shown in Figures 2 and 3, the multiple gears 60 include a transmission gear 40, which is a gear for transmitting the rotation of the rotating shaft 32 of the motor 30 to the output gear 50 at a predetermined gear ratio. In this embodiment, three gears (a worm gear 41, a first two-stage gear 42, and a second two-stage gear 43) are used as the transmission gear 40.
[0023] Specifically, as shown in FIG. 2, the transmission gear 40 includes a worm gear 41 fixed to the rotating shaft 32 of the motor 30 (see FIG. 3), a first two-stage gear 42 having a large diameter gear 42a and a small diameter gear 42b connected to the worm gear 41, and a second two-stage gear 43 having a large diameter gear 43a connected to the small diameter gear 42b in the first two-stage gear 42, and a small diameter gear 43b (see FIG. 3) connected to the output gear 50.
[0024] In this embodiment, the first two-stage gear 42 and the second two-stage gear 43 are used to transmit the rotation of the rotating shaft 32 of the motor 30 to the output gear 50 while adjusting the gear ratio by utilizing a small space. However, for example, the second two-stage gear 43 may be omitted and the output gear 50 may be connected to the gear 42b of the first two-stage gear 42, which has a smaller diameter, or the first two-stage gear 42 and the second two-stage gear 43 may be omitted and the output gear 50 may be connected directly to the worm gear 41.
[0025] (Output gear) As described above, the output gear 50 is a gear to which the drive shaft of the louvers of an air conditioning system (not shown) is connected, and which outputs the rotation of the rotating shaft 32 of the motor 30 as a driving force for controlling the drive shaft of the louvers.
[0026] In addition, the present invention is not limited to directly connecting the drive shaft of the louver (not shown) to the output gear 50, but it is also possible to provide a gear interposed between the rotating device 10 and the drive shaft of the louver (not shown), in which case the rotating shaft of the interposed gear is connected to the output gear 50.
[0027] (sensor) For example, air conditioners installed in automobiles are equipped with louvers. In order to drive and control this louver (not shown) to a specified state, it is particularly necessary to control the rotation angle of the output gear 50, and sensor 70 is a sensor that detects the rotation angle of the output gear 50 in order to control the rotation angle of the output gear 50.
[0028] Then, based on the detected rotation angle of the output gear 50, the rotation of the motor 30 is controlled, and the output gear 50 is rotated so that the louver (not shown) is brought into a predetermined state.
[0029] In this embodiment, a rotary-type resistive position sensor is used for the sensor 70, and as shown in Figures 2 and 3, the sensor 70 comprises three first connection terminals 71 for input and output to obtain a rotation angle signal corresponding to the rotation angle of the output gear 50, a resistor substrate 72 in which resistors to which the first connection terminals 71 are electrically connected are printed on a resin substrate, a rotating body (not shown) that has a conductive brush (not shown) that contacts the resistors and rotates integrally with the output gear 50 to detect the rotation angle, a base portion 73 for arranging these, and a cover portion 74 that is provided at a position corresponding to the rotating body (not shown) and forms a housing of the sensor (hereinafter referred to as the sensor housing) together with the base portion 73. The resin substrate of the resistor substrate 72 is made of, for example, an epoxy resin. The thickness of this resin substrate is, for example, about 300 μm to about 1600 μm. Moreover, this resin substrate is harder than the flexible wiring substrate 80 .
[0030] In this embodiment, a rotating body (not shown) that is engaged with the rotating shaft of the output gear 50 and rotates integrally with the output gear 50 is rotatably mounted on the base portion 73, and a resistor substrate 72 is arranged at a distance from the rotating body.A resistive position sensor is used for the resistor substrate 72, and the output resistance value changes as a result of a conductive brush (not shown) provided on the resistor substrate 72 side of the rotating body changing position as the rotating body rotates and comes into contact with the resistor of the resistor substrate 72. However, the sensor that detects the rotation angle may be a type that uses a sensor substrate on which a conductive portion is formed so that the conductive brush is repeatedly turned on and off as the rotating body rotates, and detects the rotation angle from the number of times this ON-OFF is repeated.
[0031] The base portion 73 is provided with a terminal arrangement portion 75 for arranging terminals, as shown in a dotted frame, and this terminal arrangement portion 75 is configured to accommodate not only the three first connection terminals 71 for input / output of the sensor 70, but also the two second connection terminals 35 for the motor 30.
[0032] Specifically, as shown in FIG. 2, the output gear 50 and the sensor 70 are arranged on the side (the side of the second housing 27 in the X-axis direction) of the main body 31 of the motor 30 along the second surface 25 of the second housing 27 that is approximately perpendicular to the direction of the rotation shaft 32 of the motor 30 (the Z-axis direction), and the base 73 of the sensor 70 is formed so that the terminal arrangement portion 75 extends from the sensor 70 toward the motor 30 so that the second connection terminal 35 for the motor 30 can be arranged in the terminal arrangement portion 75.
[0033] The terminal arrangement portion 75 is arranged so that the first connection terminal 71 is arranged on the side away from the motor 30, and the second connection terminal 35 is arranged on the side closer to the motor 30, thereby enabling electrical connection between the motor terminal 33 of the motor 30 and the second connection terminal 35 for the motor 30 over a short distance. Here, electrical connection refers to electrically connecting two components directly or via another component.
[0034] In this way, by not only fixing the three first connection terminals 71 for input and output of the sensor 70 to the base portion 73 of the sensor 70, but also fixing the two second connection terminals 35 for the motor 30, there is no need to provide a fine structure for fixing the two second connection terminals 35 for the motor 30 to the housing 20 (see Figure 1), which prevents the mold for forming the housing 20 from becoming complicated and makes it possible to reduce the manufacturing cost of the housing 20.
[0035] Alternatively, the terminal arrangement portion 75 of the base portion 73 of the sensor 70 must be such that the two second connection terminals 35 for the motor 30 can be arranged thereon. However, as can be seen from Figures 2 and 3, in order to accommodate the two second connection terminals 35, it is only necessary to design the terminal arrangement portion 75 so that it extends toward the motor 30. This means that the mold or the like for molding the base portion 73 does not become complicated, and therefore manufacturing costs do not increase, making it possible to reduce manufacturing costs in terms of the total cost of the entire product.
[0036] In this embodiment, the first connection terminal 71 and the second connection terminal 35 are fixed to the terminal arrangement portion 75 of the base portion 73 of the sensor 70 by means of adhesive or the like. However, for example, a protrusion corresponding to each terminal (first connection terminal 71 and second connection terminal 35) may be formed on the terminal arrangement portion 75, and a hole portion corresponding to the protrusion may be provided in each terminal (first connection terminal 71 and second connection terminal 35). In this case, the projections of the terminal arrangement portion 75 are press-fitted into the holes of the respective terminals (the first connection terminals 71 and the second connection terminals 35 ), and the respective terminals are fixed to the terminal arrangement portion 75 . Even when such fixing is performed, since a protrusion is simply formed on the planar terminal arrangement portion 75, the mold for forming the base portion 73 does not become complicated, and the manufacturing cost does not increase.
[0037] Furthermore, by arranging the second connection terminal 35 on the base portion 73, it is possible to prevent the second connection terminal 35 from coming into contact with the components housed within the housing 20 (see FIG. 1), thereby improving reliability.
[0038] In addition, by arranging the three first connection terminals 71 for input / output of the sensor 70 and the two second connection terminals 35 for the motor 30 in such a manner that they are concentrated on the base portion 73, it is possible to prevent the storage of the terminals from becoming complicated, and it is possible to design the rotating device 10 to be smaller overall.
[0039] The two second connection terminals 35 for the motor 30 thus arranged and fixed to the terminal arrangement portion 75 of the base portion 73 are electrically connected to the respective motor terminals 33 of the motor 30 by the flexible wiring board 80. Flexible wiring board 80 has a structure in which an adhesive layer is formed on a film (resin substrate) having a thickness of, for example, about 12 μm to 50 μm, and a conductor having a thickness of, for example, about 12 μm to 50 μm is printed or attached on the adhesive layer. The film is made of an insulating resin material such as polyimide or polyester. The conductor is made of a metal material such as copper. The adhesive layer is made of an epoxy resin or an acrylic resin. Such a flexible wiring board 80 is a board that can be restored to its original shape even if it is bent at an angle of 90 degrees or more.
[0040] The electrical connection between the second connection terminal 35 for the motor 30 and the motor terminal 33 may be a connection using a lead wire. When lead wires are used, the lead wires themselves are thin and difficult to handle, so the flexible wiring board 80 as in this embodiment is preferable in terms of ease of handling.
[0041] Therefore, by making the electrical connection between the second connection terminal 35 for the motor 30 and the motor terminal 33 using the flexible wiring board 80, the assembly work of the rotating device 10 can be made easier, thereby making it possible to reduce manufacturing costs.
[0042] On the other hand, in this embodiment, the shape, etc. of the flexible wiring board 80 is devised to improve the reliability of the connection between the second connection terminal 35 for the motor 30 and the flexible wiring board 80 and the connection between the motor terminal 33 and the flexible wiring board 80, as will be explained below with reference to Figures 3 and 5.
[0043] FIG. 5 is a perspective view showing a state in which the motor terminal 33 of the motor 30 and the second connection terminal 35 for the motor 30 provided on the sensor 70 are connected by a flexible wiring board 80. As shown in FIG.
[0044] As shown in Figures 3 and 5, the second connection terminal 35 for the motor 30 has one end side of the second connection terminal 35 bent in a direction away from the base portion 73, and has a connection portion 35a extending in a direction away from the base portion 73. In the illustrated example, the connection portion 35a extends from the base portion 73 toward the first surface portion 21 of the housing 20.
[0045] The flexible wiring board 80 has one end surface 82 connected to the connection portion 35a of the second connection terminal 35 for the motor 30, and the one end surface 82 is provided with an electrical connection portion having a hole portion 82a that engages with the connection portion 35a.
[0046] Therefore, by performing soldering so that the connection portion 35a is engaged with the hole portion 82a, a firm electrical connection can be achieved, thereby making it possible to prevent poor contact.
[0047] The flexible wiring board 80 also has another end surface 81 connected to the motor terminal 33 of the motor 30 , and the other end surface 81 is also provided with an electrical connection portion having a hole 81 a that engages with the motor terminal 33 .
[0048] Therefore, by performing soldering so that the motor terminals 33 are engaged with the holes 81a, a firm electrical connection can be achieved, thereby preventing poor contact.
[0049] In addition, the flexible wiring board 80 has an intermediate surface connecting one end surface 82 connected to the connection portion 35a of the second connection terminal 35 of the motor 30 and the other end surface 81 connected to the motor terminal 33 of the motor 30, and the intermediate surface is provided with a bent portion 83 that arranges the one end surface 82 and the other end surface 81 so as to be approximately perpendicular to each other, and the bent portion 83 is a bent portion having a folded-back structure as shown in Figure 3. Instead of providing the folded portion 83 with a folded structure, a curved structure may be provided. In the illustrated example, the extending direction of one end surface 82 and the extending direction of the other end surface 81 intersect with each other at a bent portion 83 . The bent portion 83 is provided midway from the second connection terminal 35 to the motor terminal 33 of the motor 30, and changes the angle (bending angle) between the other end surface 81 and one end surface 82 in response to vibrations, etc., and exhibits spring properties.
[0050] For example, if the second connection terminal 35 of the motor 30 and the motor terminal 33 of the motor 30 are linearly connected by the flexible wiring board 80, when the motor 30 or the sensor 70 vibrates due to vehicle vibrations or the like, tensile stress is likely to be applied to the connection portion between the second connection terminal 35 for the motor 30 and the flexible wiring board 80 and the connection portion between the motor terminal 33 and the flexible wiring board 80, which may result in poor connection or breakage of the flexible wiring board 80.
[0051] On the other hand, in this embodiment, the second connection terminal 35 of the motor 30 and the motor terminal 33 of the motor 30 are connected by the flexible wiring board 80 via the bent portion 83 having a folded-back structure. With this configuration, the bent portion 83 having the folded structure deforms so that the bent angle changes in response to vibration or the like, and exhibits spring properties. Therefore, the bent portion 83 prevents tensile stress, etc. from being applied to the connection portion between the second connection terminal 35 for the motor 30 and the flexible wiring board 80 and the connection portion between the motor terminal 33 and the flexible wiring board 80, thereby suppressing the occurrence of poor connection and also suppressing the occurrence of breakage, etc. of the flexible wiring board 80 itself.
[0052] Incidentally, even if the bend portion 83 is configured with only a single bend without a fold-back structure, a portion of excess length will be created compared to the case where the wiring is linear, and the effects of tensile stress, etc. can be reduced, so such a bend portion may be used; however, as in this embodiment, the use of a bend portion having a fold-back structure is preferable because the bend portion 83 is less susceptible to the effects of tensile stress, etc.
[0053] Therefore, by providing the flexible wiring board 80 with the bent portion 83 having a folded structure as in this embodiment, the reliability of the rotating device 10 can be improved.
[0054] The rotating device 10 as described above is used, for example, in an air conditioning system of a vehicle such as an automobile, and the case where it is used in an air conditioning system of a vehicle will be briefly described below. FIG. 6 is a schematic diagram for explaining an air conditioning system 100 including the rotating device 10 of the embodiment, and FIG. 7 is a diagram showing a vehicle including the air conditioning system 100 of FIG.
[0055] As shown in FIG. 6, the air conditioning system 100 includes a blower fan 101, an evaporator 102, a heater 103, and a louver 104, which are arranged in the front portion FR of the vehicle (see FIG. 7).
[0056] More specifically, a blower fan 101 is disposed on the suction port 100a side of the air conditioning system 100, and an evaporator 102 for cooling the air blown out from the blower fan 101 is disposed downstream in the air flow direction.
[0057] Furthermore, a heater 103 is disposed downstream of the evaporator 102 in the air flow direction, and a louver 104 is disposed between the evaporator 102 and the heater 103. The louver 104 controls the amount of air flowing from the evaporator 102 side to the heater 103 side, thereby adjusting the air temperature to an appropriate temperature.
[0058] The air adjusted to an appropriate temperature is then supplied to the vehicle cabin through an air outlet provided in the vehicle cabin via a duct or the like. In the above-mentioned air conditioning system 100, for example, the rotating shaft 104a of the louver 104 is connected to the engagement portion 51 (see FIG. 4) of the output gear 50 of the above-mentioned rotating device 10. Therefore, as described above, the rotation of the louvers 104 is controlled by the rotating device 10 (see the double-headed arrow in FIG. 6) so that they are brought into a predetermined state.
[0059] Note that the above is merely one example of the rotating device 10 in the air conditioning system 100. For example, the air conditioning system 100 may switch the air flow path (duct path) between circulating air inside the vehicle cabin and taking in air from outside the vehicle into the vehicle cabin, and louvers are also provided at the switching portion. Therefore, the rotating device 10 can be suitably used to control the louvers provided at this switching portion.
[0060] Although the present invention has been described based on the embodiment, the present invention is not limited to the embodiment. In the above embodiment, the case has been described where the sensor 70 is disposed to detect the rotation angle of the output gear 50 , but the detection of the rotation angle is not limited to the output gear 50 .
[0061] For example, if the relationship between the rotation angle of one of the multiple transmission gears 40 and the drive state of a louver (not shown) is determined, the rotation angle of that transmission gear can be detected by sensor 70, and the rotation of motor 30 can be controlled based on that rotation angle, thereby controlling the drive of the louver (not shown). Therefore, the sensor 70 for detecting the rotation angle may be one that detects the rotation angle of the transmission gear 40 .
[0062] In addition, in the above embodiment, a rotary type resistive position sensor was used as the sensor 70, but the sensor 70 does not necessarily have to be a rotary type resistive position sensor, and may be a non-contact rotary type position sensor.
[0063] However, since a resistive position sensor has a structure in which a conductive brush is in firm physical contact with a resistor, detection errors due to effects such as vehicle vibrations are less likely to occur, so it is preferable to use a rotary-type resistive position sensor for sensor 70.
[0064] In the above embodiment, the rotation angle of the output gear 50 is detected by a sensor, but this is not limited to this. As long as the rotation angle of the output gear 50 can be controlled, the rotation angle of another gear may be detected by the sensor instead of the rotation angle of the output gear 50.
[0065] In addition, in the above embodiment, one end side of the second connection terminal 35 for the motor 30 is bent, but a bent portion may be provided between a part of the second connection terminal 35 facing the base portion 73 and the connection portion 35a. In this case, the connection portion 35a becomes the end portion of the second connection terminal 35.
[0066] In addition, in the above embodiment, the intermediate surface is provided with a bent portion 83 that arranges one end surface 82 and the other end surface 81 so as to be approximately perpendicular to each other, but this is not limited to this, and it is also acceptable to provide a bent portion 83 on the intermediate surface that intersects the extending direction of one end surface 82 and the extending direction of the other end surface 81.
[0067] Furthermore, in the above, the rotating device 10 is described as being used in an air conditioner for a vehicle such as an automobile, but the rotating device 10 is not limited to being used in an air conditioner for a vehicle, and can be suitably used in vehicles such as an airplane.
[0068] Thus, it goes without saying that various modifications are possible without departing from the spirit of the present invention, and such modifications without departing from the spirit of the present invention are also included in the technical scope of the present invention, which will be clear to those skilled in the art from the description of the claims.
