Description

This application is a divisional application of the patent application with application number 201911358539.3, application date December 25, 2019, and invention name “rotating equipment”. Technical Field

[0001] The present invention relates to a rotating device which includes a motor and supplies a rotating driving force to various devices. Background Art

[0002] In the past, many types of motors were used to supply rotational driving force to various devices. Motors are electrical components and therefore should be kept away from moisture and dust. However, electrical devices such as automobiles used outdoors are sometimes difficult to avoid moisture and dust due to their use environment. In such use environments, motors are used in a sealed container.

[0003] Since the motor generates driving force, it is required to be firmly fixed to the housing. However, in a closed container, since a through hole for installation cannot be provided in the housing, installation becomes complicated or requires space for installation. For example, if a strip-shaped pressing member such as metal is wound around the motor and its end is fastened, space for the fastening is required, and in addition, the operation becomes complicated, resulting in increased costs.

[0004] Furthermore, if a flange is pre-set on the motor and fastened, a space for fastening is still required, and the simplification of the operation is not sufficient. Therefore, if the motor is firmly mounted on the housing, not only is it difficult to miniaturize the sealed container, but also special processing or an increase in the number of parts for mounting are required, resulting in complicated assembly and increased costs. (Prior art literature) (Patent Document)

[0005] Patent Document 1: Japanese Patent Application Publication No. 2014-147284 Summary of the invention (Problem to be solved by the invention)

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 is a perspective view of a rotating device according to an embodiment of the present invention. Figure 2 is an exploded stereogram. Figure 2 In the figure, some parts contained in the housing 4 are not directly related to the structure of the present invention, so they are omitted from the figure (the same applies to the following figures). In fact, the housing 4 also contains a reduction gear set that reduces the rotational driving force of the motor 3, so as to output the required rotational driving force to the outside.

[0014] The rotary device 1 is formed by accommodating a motor 3 in a sealed container, and the sealed container is formed by a housing 4 with one side opened and a cover 5 combined to cover the opening. In this embodiment, the motor 3 is held by a holder 2, and the holder 2 also holds a wiring substrate 6.

[0015] In addition, the motor 3 is powered and electrically controlled via the wiring substrate 6, so that it is controlled to a desired number of rotations. The housing 4 is provided with a connection port 42 for introducing a wiring harness (electrical wires, not shown), which is used to supply power to the wiring substrate and transmit electrical signals. The wiring substrate 6 is formed with a plurality of holes 61 that serve as terminals, which are electrically connected to an external power source or an external control device by press-fitting with a connector (not shown) installed at the front end of the wiring harness.

[0016] exist Figure 3 2 shows an enlarged stereoscopic view of the retainer 2. In addition, in order to show the state in which the motor 3 is retained by the retainer 2, Figure 4 2 shows an enlarged front view after only the holder 2 and the motor 3 are removed from the rotating device 1 . The holder 2 is made of resin and has a pair of pieces (hereinafter referred to as holding pieces) 21, 21 and a body 22 connected to the end 21x side of the pair of holding pieces 21, 21. The body 22 is hard, but the pair of holding pieces 21, 21 are elastic and are formed to move closer to or away from each other.

[0017] The pair of retaining 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 protrusion 212 protruding in a circular arc-shaped cross section at the other end 21y. The protrusion 212 protrudes from the beam portion 211 toward the outer peripheral surface of the motor 3 in the direction from one retaining piece 21 of the pair of retaining pieces 21, 21 toward the other retaining piece 21. Figure 4 As shown, in the flat plate-shaped beam portion 211, a position slightly close to the other end 21y contacts the motor 3 (this contact position is referred to as "intermediate contact portion 21a").

[0018] In the intermediate contact portion 21a, a pair of retaining pieces 21, 21 are arranged in an axial direction (relative to the rotation axis of the motor 3) with respect to the rotation axis of the motor 3. Figure 4 The pair of retaining pieces 21 and 21 hold the outer peripheral surface of the housing of the motor 3 in a direction perpendicular to the vertical direction of the paper surface (i.e., in the extending direction of the retaining piece 21, the width of the motor 3 becomes the maximum width). The pair of retaining pieces 21 and 21 hold the motor 3 in a direction perpendicular to the axial direction of the rotating shaft of the motor 3, so that the rotational motion and vibration of the motor 3 can be effectively suppressed by the pair of retaining pieces 21 and 21, and the driven motor 3 can be stably held.

[0019] In addition, if Figure 4 As shown, in the protrusion 212 protruding inward (outer peripheral surface of the housing of the motor 3), the motor 3 is contacted at a position closer to the one end 21x than the top (the most protruding position where the width of the motor 3 becomes the largest). In the protrusion 212, the part that contacts the motor 3 at a position close to the one end 21x becomes an end side contact portion (hereinafter referred to as "the 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 the position where the width of the motor 3 becomes the largest. Thus, the retainer 2 holds the motor 3 in a manner in which the motor 3 is clamped by the intermediate contact portion 21a and the other end side contact portion 21b.

[0020] In the central part of the extension direction of the main body 22, a curved recess 221 corresponding to the outer peripheral surface of the motor 3 is formed. The motor 3 is positioned by embedding the outer peripheral surface of the motor 3 into the recess 221, and the retainer 2 stably holds the motor 3 by acting together with the elastic force of a pair of retaining plates 21, 21.

[0021] When trying to hold the motor 3 with the holder 2, Figure 2The positional relationship between the two shown in the figure starts to bring the retainer 2 relatively close in this state. Even if the protrusion 212 contacts the outer peripheral surface of the motor 3, the two are still brought close in this state. At this time, a pair of retaining plates 21, 21 expand due to their elasticity, and the protrusion 212 narrows again after passing over the outer diameter of the motor 3, so that the outer peripheral surface of the motor 3 is embedded in the recess 221 and contacts the middle contact portion 21a and the other end side contact portion 21b, and finally the motor 3 is retained in the retainer 2.

[0022] Alternatively, the holder 2 may be brought closer to the axial direction of the rotating shaft of the motor 3 and inserted into the holding region of the motor 3 formed by the recess 221 , the beam 211 , and the protrusion 212 , so that the motor 3 is held by the holder 2 . As mentioned above, Figure 4 The holder 2 shown is in a state where the motor 3 is held.

[0023] exist Figure 5 2 shows a perspective view of the interior of the housing 4 viewed from above. The housing 4 is a box-shaped container with an upper opening, and the retainer 2 for holding the motor 3 is assembled into the housing 4 in such a manner that the other ends 21y of a pair of retaining pieces 21, 21 are disposed toward the bottom 41 of the housing 4.

[0024] In more detail, a pair of grooves 43 are respectively provided on two opposing inner wall surfaces 45 vertically extending from the bottom 41 of the housing 4 toward the cover 5, and the outer side surfaces of the pair of retaining pieces 21, 21 are slidably inserted, thereby assembling the retainer 2 holding the motor 3 into the housing 4. Then, as described below, the retainer 2 holding the motor 3 is fixed in the housing 4 by pressing the portion of the main body 22 side of the retainer 2 toward the bottom 41 of the housing 4.

[0025] Figure 6 2 is a top view showing a state where the retainer 2 holding the motor 3 is assembled into the housing 4. Figure 7 is its AA cross-section diagram. Figure 6 and Figure 7 As shown, the outer side surfaces of the pair of retaining 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 retaining pieces 21, 21 are restrained from expanding in the direction away from each other. That is, the pair of grooves 43 constitute the "pressing portion" in the present invention.

[0026] Therefore, the other ends 21y of the pair of holding pieces 21, 21 of the assembled holder 2 are suppressed from expanding in the separation direction, and the pair of holding pieces 21, 21 clamp 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 pushed toward the motor 3 side (in the direction of approaching each other) by the pushing portion (a pair of grooves 43) with a small number of parts, no space required, and a simple structure, thereby firmly holding the motor 3.

[0027] In particular, in the present embodiment, at a position closer to the other end 21y than the intermediate contact portion 21a that contacts the outer diameter of the motor 3, the motor 3 is clamped and held by the other end side contact portion 21b that protrudes toward the motor 3 side more than the intermediate contact portion 21a, and this state is maintained by a pair of grooves 43 constituting a "pushing portion", thereby being able to hold the motor 3 more firmly.

[0028] In addition, in this embodiment, ribs 44 are provided on the groove wall surface 43a of the housing 4 constituting the pair of grooves 43 in the vertical direction from the bottom 41 toward the cover 5. The ribs 44 are Figure 5 Only one of them can be seen in the figure, but both are provided on the pair of grooves 43. The rib 44 protrudes from the groove wall surface 43a at the same height within a certain length range in the vertical direction from the bottom 41 toward the cover 5, but the height gradually decreases as it moves away from the bottom 41 and disappears in the middle of the groove 43, thereby, the end surface of the rib 44 is formed to be inclined.

[0029] The rib 44 applies force to the other end side of the pair of holding pieces 21, 21 from the outside. That is, by providing the rib 44, the "pressing portion" of this embodiment applies force to the other ends of the pair of holding pieces 21, 21 in a direction toward each other. Therefore, the motor 3 is held more firmly by the holder 2.

[0030] Furthermore, since the end surface of the end of the rib 44 away from the bottom 41 is formed inclined as described above, when the outer side surfaces of the pair of retaining pieces 21, 21 are slidably fitted into the pair of grooves 43, the retainer 2 holding the motor 3 is smoothly pressed in by the end of the rib 44. Therefore, the retainer 2 holding the motor 3 can be easily assembled into the housing 4 in a pressed-in state.

[0031] like Figure 3 , Figure 4 As shown, a pair of claws (hereinafter referred to as holding claws) 23, 23 for holding the wiring substrate 6 are provided on the main body 22 of the holder 2. The pair of holding claws 23, 23 extend from the main body 22 to the opposite direction of the pair of holding pieces 21, 21. In addition, the pair of holding claws 23, 23 are respectively forked immediately from the main body 22 to form a pair of pieces (hereinafter referred to as holding claw pieces) 23a, 23a'.

[0032] The pair of holding claw pieces 23a, 23a' are arranged side by side in a state separated from each other at the front end in the direction perpendicular to the direction from one holding piece 21 to the other holding piece 21 (the width direction of the holding piece 21) in the pair of holding pieces 21, 21. In the example of the present embodiment, the pair of holding claw pieces 23a, 23a' are bifurcated near the main body 22 at the base end, but may be separated slightly at the front end. A pair of protrusions (hereinafter referred to as holding protrusions) 23b, 23b' protruding in directions opposite to each other are provided at the front end of each of the pair of holding claw pieces 23a, 23a'.

[0033] Figure 8 2 is an exploded perspective view showing the positional relationship of the wiring substrate 6 fixed to the cover 5 by the retainer 2. The wiring substrate 6 is rectangular in shape, and a pair of semicircular notches 61, 61 are formed at the outer edges of the opposing sides. A pair of holding claws 23, 23 are respectively fitted into the pair of notches 61, 61. In the present invention, the "outer edge" when referring to the outer edge of the wiring substrate refers to the outer edge of the outer shape of the wiring substrate when viewed from above, and does not include the edge of the opening when the wiring substrate is provided with a through hole.

[0034] The semicircular ends of the pair of notches 61 and 61 have opposing areas 61a and 61a, and the pair of holding claws 23a and 23a' contact the areas 61a and 61a. These opposing areas 61a and 61a constitute the first and second opposing parts of the edge of the wiring substrate 6. In addition, the pair of notches 61, 61 may not be provided, for example, a through hole may be provided on the wiring substrate, and a pair of retaining claws may be inserted into the through hole for engagement. In this case, the edge of the opening of the through hole corresponds to the "edge" of the wiring substrate retained by the retaining claws mentioned in the present invention, and the area in contact with the pair of retaining claws corresponds to the "opposing first portion and second portion" mentioned in the present invention.

[0035] The wiring board 6 is sandwiched in the thickness direction between the pair of holding protrusions 23 b and 23 b ′ of the holding claws 23 and the upper surface 222 of the body 22 (the surface on the side where the pair of holding claws 23 and 23 are provided).

[0036] In this state, if Figure 2 As shown, the wiring substrate 6, the holder 2 and the motor 3 are sandwiched between the housing 4 and the cover 5, and the cover 5 covers the opening of the housing 4 and fixes the two. The fixing is achieved by 6 (refer to Figure 6 ) protrusions (hereinafter referred to as locking protrusions) 46 are respectively engaged with six (refer to Figure 8 ) hole portion (hereinafter referred to as the locking hole) 51.

[0037] When the cover 5 is fixed to the housing 4, the wiring substrate 6, the holder 2, and the motor 3 sandwiched therebetween are pressed. Therefore, as described above, the main body 22 of the holder 2 is pressed toward the bottom 41 of the housing 4, so that the holder 2 holding the motor 3 is fixed in the housing 4. In addition, the wiring substrate 6 is also fixed to the cover 5 via the holder 2.

[0038] Fig. 9 This is a BB cross-sectional view of the rotating device 1 assembled in the above manner (refer to Figure 1 ,exist Figure 6 The corresponding part of the BB section is also shown in FIG. 1 ). In addition, Fig.10 The CC cross-sectional view of the rotating device 1 is also shown (see Figure 1 ,exist Figure 6 The corresponding part of the CC section is also shown in FIG. 1 ). Furthermore, Fig.11 This is a perspective view from an angle where the top 53 of the cover 5 can be seen. Fig.11 The lower side of Figure 1 In the oblique lower left direction.

[0039] The bottom 41 of the housing 4 and the top 53 of the cover 5 are opposite to each other, and the housing is formed by the two. A gasket 7 is provided between the housing 4 and the cover 5 to ensure the airtightness of the housing formed by the two. Figure 6 In addition to the housing 4, a gasket 7 is also shown.

[0040] A pair of protrusions (hereinafter referred to as biasing protrusions) 52 are provided upright on the top 53 of the cover 5. Fig.10 As shown, the urging protrusion 52 is configured to be embedded in a pair of retaining claws 23a and 23a' in a wedge shape. Fig. 9 , a partial cross section of the urging protrusion 52 is shown, and therefore it can be seen that the urging protrusion 52 is located in front of the holding claw piece 23a'.

[0041] As described above, the outer sides of the pair of holding claws 23a and 23a' contact the opposing regions 61a and 61a of the notch 61. If the force-applying protrusion 52 is inserted into the gap between the two ends in a wedge shape, a force is applied in a direction in which the gap between the two is further expanded, that is, the force applied to the regions 61a and 61a, which are the edges of the wiring substrate 6, is increased. In addition, the term "wedge-shaped" in the present invention does not necessarily mean that the shape of the force-applying protrusion is a wedge shape, but refers to a form in which the force-applying protrusion is pressed into the gap between the pair of holding claws and functions as a wedge to widen the gap.

[0042] In addition, a pair of retaining protrusions 23b and 23b' are provided at the front end portions of each of the pair of retaining claw pieces 23a and 23a'. If the gap between the pair of retaining claw pieces 23a and 23a' expands, the retaining protrusions 23b and 23b' act by pressing against the upper surface 222 of the main body 22, thereby strengthening the force in the thickness direction of the wiring substrate 6.

[0043] As described above, the biasing protrusions 52 provided on the cover 5 function to firmly hold the wiring board 6 . Even if the pair of holding protrusions 23b, 23b' are not provided on the holding claw pieces 23a, 23a', the force applied by the force-applying protrusion 52 to the holding claw pieces 23a, 23a' toward the edge of the wiring substrate 6 can also hold the wiring substrate 6, but the pair of holding protrusions 23b, 23b' can hold it more firmly.

[0044] As described above, according to the rotary device 1 of this embodiment, the motor 3 and the wiring board 6 can be firmly held in the sealed container (casing) formed by the housing 4 and the cover 5 with a small number of parts, without requiring space and with a simple structure.

[0045] The above is a description of the rotating device of the present invention by enumerating preferred embodiments, but the rotating device of the present invention is not limited to the configuration of the above embodiments. For example, in the above embodiments, the shell composed of the outer shell 4 and the cover 5 is described as an example of a sealed container, but in the present invention, the shell may not be a sealed container. Even if it is a common container that is not sealed, the motor and the wiring substrate can be firmly held in the shell that at least has the outer shell with a small number of parts, and no space is required, and the structure is simple.

[0046] In addition, in the above embodiment, the structure of using the retainer 2 to retain the motor 3 and the wiring substrate 6 in the shell composed of the shell 4 and the cover 5 is cited as an example for explanation, but even if only one side is retained, the retained motor and wiring substrate can be firmly retained.

[0047] In addition, in the above embodiment, the assembly method is described in the order of holding the motor 3 in the holder 2 and mounting it in the housing 4, then mounting the wiring substrate 6 and mounting the cover 5 in the housing 4, but the assembly order is not limited to this. For example, the motor 3 may be placed on the housing 4, and the holder 2 may be pressed to fix the motor 3 to the housing 4 by the holder 2, or the cover 5 may be mounted on the wiring substrate 6 before mounting the motor 3 in the housing 4. Several variations are listed below.

[0048] In the above 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 groove 43 alone can play a role in suppressing the other end sides 21y of the pair of holding pieces 21, 21 from expanding in the direction away from each other, so it is not necessary to form the rib 44. Of course, the formation of the rib 44 will play a role in applying a force to the other end sides 21y of the pair of holding pieces 21, 21 in the direction of approaching each other, so the configuration of this embodiment is preferred.

[0049] In the above embodiment, the pair of holding pieces 21, 21 as the pushing portion clamp the outer diameter of the motor 3 from a direction perpendicular to the axial direction of the rotating shaft of the motor 3, but depending on the different shapes of the motor, it is sometimes possible to hold it from other directions, and in the present invention, it is also possible to hold it from such a direction. Of course, by holding it from a direction like in this embodiment, the rotational motion and vibration of the motor 3 can be effectively suppressed.

[0050] In addition, in the above-mentioned embodiment, a pair of retaining plates 21, 21 contact the outer periphery of the motor 3 at a position where the middle contact portion 21a is away from the other end side contact portion 21b, but, for example, the contact portion of a pair of retaining plates with the motor (a contact surface in the case of surface contact, a contact line in the case of line contact) may have a shape corresponding to the outer periphery of the motor and be in continuous contact, while the middle contact portion is continuous with the other end side contact portion.

[0051] In this case, the push portion preferably has a shape corresponding to the pair of retaining sheets. That is, when the opposite side of the contact portion of the pair of retaining sheets with the motor is also a curved surface or a curved line, the push portion is preferably a curved surface or a curved line corresponding thereto, and when it is a plane (or a straight line) as in the present embodiment, the push portion is preferably a plane as in the present embodiment. Regardless of any configuration, it is effective to provide ribs as in the present embodiment, and therefore it is preferred. In addition to the central contact portion and the other end-side contact portion, further contacts with the motor may also be provided.

[0052] In the above-mentioned embodiment, as the retaining claws 23 provided on the retainer 2, an example is given in which a pair of retaining claws 23, 23 are respectively composed of a pair of retaining claw pieces 23a, 23a' which are divided into two forks in the middle, and only one of the retaining claws 23 also has the retaining force to retain the wiring substrate 6, but the present invention is not limited to this.

[0053] For example, the pair of holding claws may be arranged such that the front ends of the opposing long plate-like bodies are bent in a hook shape toward the opposing sides, and the wiring substrate is held by the edge therebetween. In this case, it is preferred that a force-applying protrusion is provided on the top of the cover to apply force to the pair of holding claws toward the edge of the wiring substrate. By providing such a force-applying protrusion, the wiring substrate can be firmly held.

[0054] In this case, the outer edge of the wiring substrate may be provided with a notch like the notch 61 of the present embodiment, or may not be provided. When a notch is provided, a pair of retaining claws are located in the notch to retain the edge thereof. When a notch is not provided, the linear outer edge of the wiring substrate may be maintained as it is. From the perspective of easy positioning of the wiring substrate, the former is preferred. In this case, a pair of through holes may be provided on the wiring substrate, and a pair of retaining claws may be embedded in the pair of through holes.

[0055] Furthermore, those skilled in the art can appropriately modify the rotary device of the present invention based on conventional knowledge, and such modifications are naturally included in the scope of the present invention as long as they have the configuration of the present invention.
