Description
The application is a divisional application of patent application with the application number 201911358539.3, the application date 2019, 12 months and 25 days and the name of 'rotating equipment'.
Technical Field
The present invention relates to a rotary device including a motor and supplying a rotational driving force to various devices.
Background
Conventionally, various motors have been used to supply rotational driving forces to various devices. The motor is an electrical component, and thus moisture and dust are avoided. However, in some electric devices of automobiles and the like used outdoors, it is difficult to avoid moisture and dust due to the use environment, and in such use environment, the motor is used in a state of being accommodated in a closed container.
The motor is required to be firmly fixed to the housing because it generates a driving force. However, in the sealed container, since the through hole for mounting cannot be provided in the housing, the mounting becomes complicated or a space for mounting is required. For example, if a belt-like pressing member such as a metal is wound around a motor and the ends thereof are fastened, a space for the fastening is required, and in addition, the work becomes complicated, which increases the cost.
In addition, if a flange is previously provided on the motor and fastened, a space for fastening is still required, and simplification of the work is insufficient. Thus, if the motor is firmly mounted to the housing, not only is it difficult to achieve miniaturization of the hermetic container, but also special processing or an increase in the number of parts for mounting is required, resulting in complicated assembly and an increase in cost.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Fig. 1 is a perspective view of a rotary device according to an embodiment of the present invention, and fig. 2 is an exploded perspective view. In fig. 2, the components contained in the housing 4 are not directly related to the constitution of the present invention, and therefore, are not shown (the same applies to the following drawings). In practice, a reduction gear set or the like for reducing the rotational driving force of the motor 3 is also accommodated in the housing 4 for outputting the required rotational driving force to the outside.
The rotary device 1 is configured by accommodating a motor 3 in a closed container configured by a housing 4 having one surface opened and a cover 5 combined so as to cover the opening. In the present embodiment, the motor 3 is held using the holder 2, and the holder 2 also holds the wiring substrate 6.
The motor 3 is electrically controlled by supplying power through the wiring board 6, and is controlled to a desired number of rotations. The housing 4 is provided with a connection port 42 for introducing a wire harness (electric wire, not shown) for supplying power to the wiring board and transmitting an electric signal. The wiring board 6 is formed with a plurality of holes 61 serving as terminals, and is press-fitted to a connector (not shown) attached to the front end of the wire harness, thereby electrically connected to an external power source or an external control device.
Fig. 3 shows an enlarged perspective view of the holder 2. In order to show a state in which the motor 3 is held by the holder 2, fig. 4 shows an enlarged front view of the rotary apparatus 1 after only the holder 2 and the motor 3 are taken out.
The holder 2 is made of resin, and includes a pair of sheets (hereinafter referred to as holding sheets) 21, 21 and a main body 22 connected to a portion of one end 21x side of the pair of holding sheets 21, 21. The main body 22 is hard, but the pair of holding pieces 21, 21 has elasticity and is formed so as to be close to or apart from each other.
The pair of holding pieces 21, 21 includes a beam portion 211 extending in a flat plate shape from one end 21x connected to the main body 22, and a protruding portion 212 protruding in an arc shape in cross section at the other end 21 y. The protruding portion 212 protrudes from the beam portion 211 toward the outer peripheral surface of the motor 3 in a direction from one retaining piece 21 toward the other retaining piece 21 of the pair of retaining pieces 21, 21. As shown in fig. 4, the flat plate-like beam portion 211 is in contact with the motor 3 at a position slightly closer to the other end 21y (this contact position is referred to as "intermediate contact portion 21 a").
In the intermediate contact portion 21a, the pair of holding pieces 21, 21 sandwich the outer peripheral surface of the housing of the motor 3 from a direction perpendicular to the axial direction of the rotation shaft of the motor 3 (a vertical direction with respect to the paper surface of fig. 4) (i.e., a position where the width of the motor 3 becomes the maximum width in the extending direction of the holding piece 21). Since the pair of holding pieces 21, 21 sandwich the motor 3 from the direction perpendicular to the axial direction of the rotation shaft of the motor 3, the pair of holding pieces 21, 21 can effectively suppress the rotational movement and vibration of the motor 3, and can stably hold the motor 3 that is driven.
As shown in fig. 4, the motor 3 is contacted with the protruding portion 212 protruding inward (the outer peripheral surface of the housing of the motor 3) at a position closer to the one end 21x than the top portion thereof (the position where the width of the motor 3 is maximized and the most protruding position). In the protruding portion 212, a portion that contacts the motor 3 at a position near the one end 21x becomes an end-side contact portion (hereinafter referred to as "other-end-side contact portion") 21b. That is, the other end side contact portion 21b contacts the motor 3 at a position on the bottom side of the housing 4 different from a position where the width of the motor 3 is maximized. Thereby, the holder 2 holds the motor 3 so that the motor 3 is sandwiched by the intermediate contact portion 21a and the other end side contact portion 21b.
In the central portion of the main body 22 in the extending direction, a curved recess 221 corresponding to the outer peripheral surface of the motor 3 is formed, and the motor 3 is positioned by fitting the outer peripheral surface of the motor 3 into the recess 221, and the retainer 2 stably retains the motor 3 by acting in conjunction with the elastic force of the pair of retaining pieces 21, 21.
When the motor 3 is attempted to be held by the holder 2, the holder 2 is brought relatively closer from the positional relationship between the two shown in fig. 2, and even if the protruding portion 212 contacts the outer peripheral surface of the motor 3, the two are brought closer together in this state, and at this time, the pair of holding pieces 21, 21 are expanded due to their elasticity, and the protruding portion 212 is narrowed again after passing over the outer diameter of the motor 3, so that the outer peripheral surface of the motor 3 is fitted into the recess 221 and contacts the intermediate contact portion 21a and the other end side contact portion 21b, and finally the motor 3 is held by the holder 2.
Further, the holder 2 may be moved closer to the axis of the rotation shaft of the motor 3, and the holding area of the motor 3 formed by the recess 221, the beam 211, and the projection 212 may be inserted in this state, so that the motor 3 is held by the holder 2.
As described above, the retainer 2 shown in fig. 4 retains the motor 3.
Fig. 5 shows a perspective view of the interior of the housing 4 from obliquely above. The housing 4 is a box-shaped container with an upper opening, and the holder 2 holding the motor 3 is assembled into the housing 4 so that the other ends 21y of the pair of holding pieces 21, 21 are arranged toward the bottom 41 of the housing 4.
More specifically, a pair of grooves 43 are provided in two opposing inner wall surfaces 45 standing in the vertical direction from the bottom 41 of the housing 4 toward the cover 5, and the outer side surfaces of the pair of holding pieces 21, 21 are slidably fitted, whereby the holder 2 holding the motor 3 is assembled into the housing 4. Then, as described later, the holder 2 holding the motor 3 is fixed in the housing 4 by pressing the portion of the holder 2 on the main body 22 side against the bottom 41 of the housing 4.
Fig. 6 is a plan view showing a state in which the holder 2 holding the motor 3 is assembled into the housing 4, and fig. 7 is A-A cross-sectional view thereof. As shown in fig. 6 and 7, the outer side surfaces of the pair of holding pieces 21, 21 are restricted by the groove wall surfaces 43a of the pair of grooves 43 in the inner wall surface 45 of the housing 4, and the other ends 21y of the pair of holding pieces 21, 21 are restrained from expanding in the direction away from each other. That is, the pair of grooves 43 constitute a "pressing portion" in the present invention.
Accordingly, the other ends 21y of the pair of holding pieces 21, 21 of the assembled retainer 2 are restrained from expanding in the separating direction, and the pair of holding pieces 21, 21 sandwich the motor 3 from the outer peripheral surface of the motor 3 toward the inside of the motor 3, thereby maintaining the state in which the motor 3 is firmly held. That is, the pair of holding pieces 21, 21 can be pressed toward the motor 3 (in the direction approaching each other) by the pressing portion (the pair of grooves 43) with a small number of components, without requiring a space, and with a simple structure, thereby firmly holding the motor 3.
In particular, in the present embodiment, the motor 3 is held by being sandwiched by the other end side contact portion 21b protruding toward the motor 3 side than the intermediate contact portion 21a, which is located closer to the other end 21y than the intermediate contact portion 21a which contacts the outer diameter of the motor 3, and this state is held by the pair of grooves 43 constituting the "pressing portion", so that the motor 3 can be held more firmly.
In the present embodiment, ribs 44 are provided on the groove wall surfaces 43a of the housing 4 constituting the pair of grooves 43 in the vertical direction from the bottom 41 toward the cover 5. Only one of the ribs 44 is visible in fig. 5, but is provided on both sides of the pair of grooves 43. The ribs 44 protrude from the groove wall surface 43a at the same height over a certain length in the vertical direction from the bottom 41 toward the cover 5, but gradually decrease in height as they go away from the bottom 41 and disappear in the middle of the groove 43, whereby the end surfaces of the ribs 44 are formed obliquely.
The rib 44 applies a force to the other end side portions of the pair of holding pieces 21, 21 from the outside. That is, the provision of the rib 44 causes the "pressing portion" of the present embodiment to apply a force to the other ends of the pair of holding pieces 21, 21 in the direction to approach each other. Therefore, the motor 3 is held more firmly by the holder 2.
Further, since the end surfaces of the ends of the ribs 44 distant from the bottom 41 are formed obliquely as described above, the retainer 2 holding the motor 3 is smoothly pushed in by the ends of the ribs 44 when the outer side surfaces of the pair of holding pieces 21, 21 are slidably fitted into the pair of grooves 43. Therefore, the holder 2 holding the motor 3 is easily assembled into the housing 4 in the pressed-in state.
As shown in fig. 3 and 4, the main body 22 of the holder 2 is provided with a pair of claws (hereinafter referred to as holding claws) 23, 23 for holding the wiring board 6. The pair of holding claws 23, 23 extend from the main body 22 in opposite directions of the pair of holding pieces 21, 21. The pair of holding claws 23, 23 are immediately bifurcated from the main body 22 to form a pair of pieces (hereinafter referred to as holding claw pieces) 23a, 23a'.
The pair of holding claw pieces 23a, 23a' are arranged side by side with the tip portions thereof spaced apart in a direction perpendicular to the direction from one holding piece 21 to the other holding piece 21 (the width direction of the holding piece 21) among the pair of holding pieces 21, 21. In the example of the present embodiment, the pair of holding claw pieces 23a, 23a' are bifurcated in the vicinity of the main body 22 at the base end portion, but may be slightly separated at the tip side. A pair of protrusions (hereinafter referred to as holding protrusions) 23b, 23b 'protruding in directions opposite to each other are provided at the tip ends of the pair of holding claw pieces 23a, 23 a'.
Fig. 8 is an exploded perspective view showing a positional relationship in which the wiring board 6 is fixed to the cover 5 by the holder 2. The wiring board 6 has a rectangular shape, and a pair of semicircular notches 61, 61 are formed in the outer edges of the opposing sides. The pair of holding claws 23, 23 are respectively fitted into the pair of notches 61, 61.
In the present invention, the term "outer edge" when referring to the outer edge of the wiring board refers to an outer edge in the outer shape of the wiring board in plan view, and does not include an edge of an opening when the wiring board is provided with a through hole.
Opposite regions 61a, 61a are provided at both ends of the semicircular arc of the pair of notches 61, and the pair of holding claw pieces 23a, 23a' contact the regions 61a, 61a. These opposing regions 61a, 61a become the 1 st and 2 nd portions opposing each other at the edge of the wiring substrate 6.
Further, the pair of notches 61, 61 may not be provided, and for example, a through hole may be provided in the wiring board, and a pair of holding claw pieces may be inserted into the through hole to be fitted. In this case, the edge of the opening of the through hole corresponds to the "edge" of the wiring board held by the holding claws mentioned in the present invention, and the area in contact with the pair of holding claw pieces corresponds to the "1 st and 2 nd opposed portions" mentioned in the present invention.
The wiring board 6 is sandwiched between the pair of holding projections 23b, 23b' of the holding claws 23 and the upper surface (surface on the side where the pair of holding claws 23, 23 are provided) 222 of the main body 22 in the thickness direction.
In this state, as shown in fig. 2, the wiring board 6, the holder 2, and the motor 3 are sandwiched between the case 4 and the cover 5, and are fixed so as to cover the opening of the case 4 with the cover 5. The fixation of the two is achieved by fitting 6 (see fig. 6) protrusions (hereinafter referred to as locking protrusions) 46 provided on the outer periphery near the opening of the housing 4 into 6 (see fig. 8) hole portions (hereinafter referred to as locking holes) 51 provided at corresponding portions of the cover 5.
When the cover 5 is fixed to the housing 4, the wiring board 6, the holder 2, and the motor 3 held therebetween are pressed. Accordingly, as described above, the holder 2 holding the motor 3 is fixed in the housing 4 by pressing the body 22 side of the holder 2 against the bottom 41 of the housing 4. The wiring board 6 is also fixed to the cover 5 by the holder 2.
Fig. 9 is a B-B sectional view of the rotary apparatus 1 assembled in the above manner (referring to fig. 1, corresponding portions of the B-B section are also illustrated in fig. 6). Fig. 10 is a C-C sectional view of the rotary apparatus 1 (referring to fig. 1, corresponding portions of the C-C section are also illustrated in fig. 6). Further, fig. 11 is a perspective view from the angle at which the top 53 of the lid 5 can be seen. The lower side in fig. 11 is the obliquely lower left direction in fig. 1.
The bottom 41 of the housing 4 is opposite to the top 53 of the cover 5 and forms a shell. A gasket 7 is provided between the case 4 and the cover 5 to ensure the sealing property of the case formed by both. In fig. 6, a gasket 7 is shown in addition to the housing 4.
A pair of protruding portions (hereinafter referred to as urging protrusions) 52 are provided upright on the top 53 of the cover 5. As shown in fig. 10, the urging projection 52 is fitted between the pair of holding claw pieces 23a, 23a' in a wedge shape. In fig. 9, since the urging projection 52 is partially shown in cross section, it is apparent that the urging projection 52 is positioned in front of the holding claw piece 23 a'.
As described above, when the pair of holding claw pieces 23a, 23a' are engaged with the opposing regions 61a, 61a of the notch 61 on the outer side thereof, and the urging projection 52 is fitted into the gap between the tip portions thereof in a wedge shape, the gap between the two is urged in a further expanding direction, that is, the urging force to the regions 61a, 61a as the edges of the wiring substrate 6 increases. In the present invention, the shape of the urging protrusion is not necessarily a wedge shape, but means a form of a wedge that is pushed into the gap between the pair of holding claw pieces and that functions to widen the gap.
Further, since the pair of holding projections 23b, 23b 'are provided at the tip ends of the pair of holding claw pieces 23a, 23a', and if the gap between the pair of holding claw pieces 23a, 23a 'is widened, the holding projections 23b, 23b' act so as to press against the upper surface 222 of the main body 22, and thus the force in the thickness direction of the wiring board 6 is also strengthened.
As described above, the biasing protrusion 52 provided on the cover 5 functions to firmly hold the wiring board 6.
Even if the pair of holding projections 23b, 23b 'are not provided on the holding claw pieces 23a, 23a', the holding claw pieces 23a, 23a 'act to hold the wiring board 6 by applying force to the edges of the wiring board 6 by the urging projections 52, but can be held more firmly by the pair of holding projections 23b, 23 b'.
As described above, according to the rotary apparatus 1 of the present embodiment, the motor 3 and the wiring board 6 can be firmly held in the sealed container (housing) formed by the case 4 and the cover 5 with a small number of components, and the space is not required, and the structure is simple.
The rotating apparatus of the present invention has been described above by way of preferred embodiments, but the rotating apparatus of the present invention is not limited to the configuration of the above embodiments. For example, in the above embodiment, the case constituted by the housing 4 and the cover 5 was described as an example of a closed container, but in the present invention, the case may not be a closed container. Even in a general container which is not airtight, a motor and a wiring board can be firmly held in a housing having at least a casing by a small number of components, and the structure is simple without requiring a space.
In the above embodiment, the case in which the motor 3 and the wiring board 6 are held by the holder 2 in the case constituted by the case 4 and the cover 5 has been described as an example, but even if only one of them is held, the effect of firmly holding the held motor and wiring board can be obtained.
In the above embodiment, the assembly method is described in terms of the order in which the motor 3 is held by the holder 2 and mounted on the housing 4, and then the wiring board 6 is mounted and the cover 5 is mounted on the housing 4, but the assembly order is not limited thereto. For example, the motor 3 may be mounted on the housing 4, the holder 2 may be pressed to fix the motor 3 to the housing 4 by the holder 2, and the cover 5 may be attached to the wiring board 6 before the motor 3 is attached to the housing 4.
Several modifications will be described below.
In the above-described embodiment, the rib 44 is formed on the groove wall surface 43a in the groove 43 as an example of the pressing portion, but the rib 44 may not be formed because the groove 43 alone can suppress the expansion of the other end sides 21y of the pair of holding pieces 21, 21 in the direction away from each other. Of course, the rib 44 is preferably formed in the present embodiment because it acts to apply force to the other end sides 21y of the pair of holding pieces 21, 21 in the direction to approach each other.
In the above-described embodiment, the pair of holding pieces 21, 21 as the pressing portion hold the outer diameter of the motor 3 from the direction perpendicular to the axial direction of the rotation shaft of the motor 3, but may be held from other directions depending on the shape of the motor, or may be held from such directions in the present invention. Of course, by holding from the direction as in the present embodiment, the rotational movement and vibration of the motor 3 can be effectively suppressed.
In the above embodiment, the pair of holding pieces 21, 21 contact the outer periphery of the motor 3 at a position where the intermediate contact portion 21a is distant from the other end side contact portion 21b, but for example, the contact portions (contact surface in the case of surface contact and contact line in the case of line contact) of the pair of holding pieces with the motor may have a shape corresponding to the outer periphery of the motor and continuously contact, and the intermediate contact portion is continuous with the other end side contact portion.
In this case, the pressing portion preferably has a shape corresponding to the pair of holding pieces. That is, when the opposite sides of the pair of holding pieces to the contact portion with the motor are curved or curved, the pressing portion is preferably curved or curved corresponding to the curved or curved side, and when the pressing portion is planar (or linear) as in the present embodiment, the pressing portion is preferably planar as in the present embodiment. The rib is preferably provided in the same manner as in the present embodiment, regardless of the configuration.
The motor may have other contact portions in addition to the intermediate contact portion and the other end contact portion.
In the above embodiment, the holding claws 23 provided in the holder 2 are exemplified as the configuration in which the pair of holding claws 23, 23 are each constituted by the pair of holding claw pieces 23a, 23a' divided into two in the middle, and only one holding claw 23 has the holding force for holding the wiring substrate 6, but the present invention is not limited to this.
For example, the pair of holding claws may be arranged such that the front ends of the opposed elongated plate-like bodies are bent to the opposite sides in a hook shape, and the wiring board may be held at the edge therebetween. In this case, it is preferable that a biasing protrusion for biasing the pair of holding claws in a direction toward the edge of the wiring board is provided at the top of the cover. By providing such a biasing protrusion, the wiring substrate can be firmly held.
In this case, the outer edge of the wiring board may or may not be provided with a notch such as notch 61 of the present embodiment. When the notch is provided, the pair of holding claws may be positioned at the notch to hold the edge of the notch, and when the notch is not provided, the linear outer edge of the wiring board may be held as it is. The former is preferable in view of easy positioning of the wiring board. In this case, a pair of through holes may be formed in the wiring board, and a pair of holding claws may be fitted into the pair of through holes.
Further, the rotary apparatus of the present invention can be appropriately changed by those skilled in the art based on conventionally known findings. The modifications mentioned above are of course included in the scope of the present invention as long as they have the constitution of the present invention.
