Description of the invention (1) The technical field to which the invention belongs (please read the precautions on the back before filling out this page) The present invention relates to a brushless motor, and in particular, to a type of vibration that can be used as a vibration alarm device The source is, for example, a small brushless motor that is used as a call function of a communication device (such as a mobile phone) or a somatosensory function of an entertainment device such as a game. BACKGROUND ART As technologies in this field, there are Japanese Patent No. 31 59202 and Japanese Patent Laid-Open No. 200 1-232290. The weights used in the brushless vibration motors described in these publications are formed in an arc shape, and are fixed to the outer peripheral portion of the rotor by welding. The weight is formed only along the outer periphery of the rotor, and this weight is welded to the rotor. 'However, if the curvature of the weight is not uniform, when the weight is fixed to the rotor, a gap occurs between the outer peripheral portion of the rotor and the inner peripheral surface of the weight, and there is a possibility that the weight cannot be reliably fixed. Fixed the problem of the rotor. Special | [] It is a small rotor with a diameter of less than 10 mm, and the installation of weights is extremely difficult. It is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Unlike the technology disclosed above, there is a Japanese fair 3-1 07 5 No. 5, but this technology is not a brushless motor. Moreover, the stone code is screwed on the rotating shaft, not the one that abuts the rotor. > SUMMARY OF THE INVENTION The present invention was created by the present invention to solve the above-mentioned problems. In particular, the purpose of the present invention is to provide a brushless motor that securely fixes a weight to the rotor. 297 mm) -5- 200301037 A7 B7 Printed by the Industrial and Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (2) • 〇 The brushless motor of the present invention is characterized by having a flux plate provided on a base member , And a circuit board provided on the flux board, and two wires provided on the circuit board, a Hall element provided on the circuit board, a shaft disposed between the two coils, and fixed to A shaft, a disc-shaped rotor that rotates integrally with the rotor, and a magnet disposed on the reel opposite side and fixed to the rotor, a weight support portion abutting the planar portion of the rotor, and integrally formed on the weight The code support portion is a weight constituted by a weight body portion that bulges radially from the outer periphery of the rotor. In this brushless motor, electric power to a coil is controlled based on an electric signal from a Hall element, and a rotor is rotated around a shaft. Such a brushless motor has a weight used as a source of vibration generation, and the weight is fixed to the rotor. This weight has not only a weight body portion that bulges radially from the outer peripheral edge of the rotor, but also a weight support portion that is integrated with the weight body portion. Since the weight support portion has a flat plate shape abutting on a flat portion of the rotor, welding and the like are easily performed at the abutting portion. This improves workability when the weight is fixed to the rotor. In particular, for small motors having a diameter of less than 10 mm, the workability of weight installation becomes better. In addition, among the constituent elements of the weight, the weight body portion has a large influence on the vibration balance, and must be formed with excellent accuracy. In consideration of deformation such as shrinkage during molding, the weight body portion is integrally formed with the weight support portion, so that it is difficult to deform the weight body portion during molding. In particular, when the body of the weight has an arc shape along the outer periphery of the rotor, the body is easily deformed during molding. Therefore, it can be said that the weight has the weight described above (please first Read the notes on the back and fill out this page)

Description of the invention (3) The support department is an effective countermeasure. (Please read the precautions on the back before filling in this page.) The weight body is drawn along the outer periphery of the rotor and extends from the outer periphery of the rotor to the coil side along the axis of the shaft. More ideal. With this configuration, the weight balance can be improved while the weight can be increased. Further, it is preferable that the outer peripheral edge of the rotor is provided with an edge portion that abuts against the weight support portion, and the weight is supported by a rising claw in the radial direction of the rotor. With such a configuration, the weight can be easily positioned on the rotor at the edge portion where the rising claw abuts on the weight support portion, and the assembling workability becomes extremely good. * Especially for small rotors with a diameter of less than 10 mm, the weight installation work is extremely good. In addition, the centrifugal force generated during high-speed rotation of the rotor can prevent the weight from falling off from the rotor, and the lifting claws can be appropriately avoided, thereby contributing to improving the durability of the motor. Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. It is also ideal to have terminals that are electrically connected to the circuit board, with a part embedded in the base member, and the other part bulging toward the side of the base member. At this time, according to the electrical signal from the Hall element to control the power supply to the coil, the rotor rotates around the shaft. The terminals used in this brushless motor are electrically connected to a circuit board, a part is embedded in the base member, and other parts are bulged toward the side of the base member. As a result, when a part of the terminal is buried in the base member, compared with a case where the mechanical support strength is guaranteed only by welding, the terminal has less instability, becomes a stable electrical connection, and significantly improves durability. Or reliability. In addition, the terminals bulge from the side of the base member. After the terminals are soldered to the desired electrical contacts of a device such as a mobile phone, it is easy to perform welding from the outside. This paper applies the Chinese National Standard (CNS) A4 standard (21 〇χ297mm) '200301037 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. Description of the invention (4) Whether it is a good confirmation operation, but it is possible to judge the quality of the welding using a camera or the like. The terminal is preferably a terminal body portion embedded in the base member, and an elastic leg portion extending laterally from the terminal body portion and exposed from the base member. In this way, as a result of using the elastic feet, the feet can be pushed toward the electrical contacts of the machine to be welded, so that poor electrical connection of the terminals can be appropriately avoided. Further, a connection piece is provided vertically in the terminal body portion, and the connection piece is preferably inserted into a through hole provided in the circuit board and exposed on the coil side. Because of this, the connection piece of the terminal can be exposed from the coil side of the circuit board, so that the electrical connection operation between the terminal and the circuit board by soldering can be performed from the coil side, which can improve the assembly workability of the motor. The circuit board is a photoresist layer having wiring on a substrate. The coil is disposed on the photoresist layer of the circuit substrate, and the conductive wire is wound in a ring shape. The circuit board is not provided with a photoresist layer. The substrate exposed portion of the substrate on which the electrical circuit substrate is exposed is formed. The end portion of the wire exposed from the inner peripheral side of the coil passes through the substrate exposed portion appearing between the coil and the substrate. It is desirable that the side extends to the outside of the coil. At this time, on a flux plate provided on the base member, a circuit substrate having a photoresist layer covering the wiring on the substrate is provided, and a coil is disposed on the photoresist layer of the circuit substrate. In addition, the end portion of the wire exposed from the inner peripheral side of the coil is an effective use of the space formed by the exposed portion of the base material and is led out to the outside. Therefore, it is not affected by the wire passing under the coil. Maintain close contact between the coil and the magnet. This is effective in increasing the thickness of the brushless motor.

Description of the invention (7) Bearing 18; the radial bearing 18 supports freely rotating Axial 2 〇. Further, two coils 25 are fixed to the circuit board 16 so as to sandwich the shaft 20. These coils 25 are made of flat wires. The circuit board 6 includes a Hall element (magnetoelectric conversion element) 27 for detecting magnetism, a motor driving element 26, and other electronic components. Power supply to the coil 25 is controlled in accordance with an electrical signal from the Hall element 27. As shown in FIGS. 1 and 2, a small disc-shaped rotor 30 having a diameter of about 8 mm is fixed to the front end of the shaft 20 so as to rotate integrally with the shaft 20. A ring magnet 31 is fixed to the lower surface of the rotor 30 via an adhesive so as to face the coil 25 provided on the circuit board 16. In addition, the base member 12 and the lid body 32 constitute a frame body 19, and the frame body 19 has a size of, for example, 11 mm m × 11 mm m × 3.6 mm in height and is miniaturized. Since such a brushless motor 10 needs to be constituted as a vibration motor, as shown in FIG. 3, in the rotor 30, a material having a high specific gravity such as sintered tungsten is used in order to distribute the weight of the shaft 20 unevenly. The constituted weight 33 is eccentrically fixed to at least a part of the rotor 30. As shown in FIGS. 3 and 4, the weight 33 is formed by a half-moon-shaped weight support portion 34 that abuts on the planar portion 30 a of the rotor 30 and is integrally formed on the weight support portion 34. An arc-shaped weight body 35 is formed from an outer peripheral edge 30 b of the rotor 30 in a radial direction of the rotor 30. The weight support portion 34 is in contact with the flat portion 30a of the rotor 30, and the welding portion 36 is fixed to the rotor 30 at two locations using laser welding or the like. The two welding portions 36 are provided so as to straddle each of the standing claws 37 and the weight support portions 34 described below. The weight support portion 34 is in a state of abutting on the flat portion 30a of the rotor 30, and the abutting portion is fixed to the rotor by an adhesive.

As described above, the weight 33 includes not only the weight body portion 35 bulging radially from the outer peripheral edge 30b of the rotor 30, but also a weight support portion 34 integrally formed with the weight support portion 35. The weight support portion 34 has a flat plate shape that abuts on the flat portion 30a of the rotor 30. Therefore, spot welding or the like is easily applied to the abutting portion, and the weight 33 is fixed to the rotor or the like Sexual mutation. In particular, the mounting workability of the weight 33 with the small-diameter rotor 30 having a diameter of less than 10 mm is improved. Among the constituent elements of the weight 33, the weight body portion 35 has a large influence on the vibration balance, and must be formed with excellent accuracy. Therefore, the shrinkage deformation during the sintering molding is considered, so that the deformation during the sintering molding is unlikely to occur in the weight body portion 35, and the weight body portion 35 is formed integrally with the weight support portion 34. In particular, when the weight body portion 35 has an arc shape along the outer periphery of the rotor 30, the weight body portion 35 is easily deformed during sintering, so the weight 33 has the weight support as described above. The portion 34 can be said to be an effective countermeasure, and the weight body portion 35 is formed in an arc shape along the outer peripheral edge 30b of the rotor, and at the same time from the outer peripheral edge 30b of the rotor 30 to the coil 25 in the axial direction of the shaft 20 Lateral extension. By using such a weight body portion 35, the weight balance of the weight 33 can be improved while the weight of the weight 33 can be appropriately increased. As shown in Figs. 3 and 5, two rising claws 37 supporting the weight 33 in the radial direction of the rotor 30 are formed on the outer peripheral edge 30b of the rotor 30 by bending. Each of the standing claws 37 is an arc-shaped edge portion 3 4 a that abuts on the code supporting portion 34 extending from the weight body portion 35 along the outer peripheral edge 3 0 b of the rotor 30.

Description of the invention (9) The main unit 3 5 is arranged between the left and right pair of standing claws 3 7 and 37. The two rising claws 37 and 37 are supported in the radial direction of the rotor 30. As described above, by abutting the edge portion 34a of the weight support portion 34 on each of the rising claws 37, positioning of the weight 33 with respect to the rotor 30 is facilitated, and assembly workability is extremely excellent. In particular, for a small-diameter rotor 30 having a diameter of less than 10 mm, the mounting workability of the weight 33 is extremely good. In addition, the centrifugal force generated during the high-speed rotation of the rotor 30 allows the weight 33 to be detached from the rotor 30, and is appropriately avoided by each of the rising claws 37, which contributes to improving the durability of the brushless motor 10. . As shown in FIG. 5, two claw portions 38 in the radial direction of the rotor 30 to support the magnetic coil 31 are formed on the outer peripheral edge 30 b of the rotor 30 by bending. Each claw portion 38 is an edge portion 31a of the ring-shaped magnet 31 extending along the outer peripheral edge 30b of the rotor 30. The magnet 31 is supported in the radial direction of the rotor 30 by two claw portions 38, 38. In this way, by abutting the edge portion 3 1 a of the magnet 31 on each of the claw portions 38, positioning of the magnet '31 with respect to the rotor 30 is facilitated, and assembly workability is extremely excellent. In particular, in a small-diameter rotor 30 having a diameter of less than 10 mm, the mounting workability of the magnet 31 is extremely excellent. In addition, the centrifugal force generated during the high-speed rotation of the rotor 30 allows the magnet 31 to be detached from the rotor 30, which is appropriately avoided by the claw portions 38, thereby contributing to the improvement of the durability of the brushless motor 10. As shown in Figs. 6 and 7, four terminals 21 to 24 are fixed to the base member 12 made of plastic by insert molding. In addition, the base ends of the pair of left and right terminals 21 and 22 are electrically connected to the circuit board 16 via solder 45.

Description of the invention (11) The circuit board 16 is penetrated and the protrusions are caulked, and the circuit board 丨 6 is fixed. In the state of the base member i 2, the connecting pieces 43 of the terminals 21 and 22 are exposed from the wire 25 side of the circuit substrate 6, and each of the connecting pieces 43 is electrically connected to the predetermined portion of the circuit substrate 16 through the solder 43. Circuit parts. In this way, since the electrical bonding work of the terminals 2 1 and 2 2 and the circuit board 16 can be performed from the coil 25 side, the workability for assembling the brushless motor 10 is significantly improved. As shown in Fig. 8, the circuit board 16 includes a base material 50 formed of a fiber-reinforced plastic (e.g., FRP). A printed wiring 52 is applied to the substrate 50 via a copper foil. The printed wiring 52 is covered with a photoresist layer 54 that prevents a short circuit between the printed wiring 52 and the coil 25 on the circuit board 16. Further, on the photoresist layer 54, a printing section 56 in which characters or marks are formed by screen printing is used to form a mounting area of the coil 25 (wire mounting area). The insulation of the printed portion 56 allows the insulation of the wire 25 and the printed wiring 52 mounted on the circuit board 16 to be more reliable. Further, a base substrate exposed portion 62 is formed on the circuit board 16. In this substrate exposure, the printed wiring 52, the photoresist layer 54 and the printed portion 56 are not laminated on the substrate 50 in the exit portion 62, and the substrate 50 is exposed. This base material exposed portion 62 is formed by cutting out a part of the printed portion 56, and is formed by connecting the inner peripheral side and the outer peripheral side of the annular coil mounting area. Therefore, as shown in FIG. 9, in the coil mounting area where the coil 25 is mounted on the circuit board 16, the substrate exposed portion 62 located under the coil 25 is “shaped” with a space through which the wire passing through the coil 25 is formed. . The height of the gap between the coil 25 and the substrate 50 is, for example, about 0.1 mm. It should be noted that the base material exposed portion 62 is formed at the time of print molding of the circuit board 16.

Description of the Invention (12) ♦ The four terminals 64 that are conducting are formed at the periphery of the coil 25. These terminals 64 are electrically connected to the outer wire side wire end portion (outer side wire end portion) 66 and the inner wire side end portion (inner side wire end portion) 68 to the outer periphery side of the coil 25 by welding. The two terminals 64 connected to the inner-peripheral-side wire end portions 68 are electrically connected to the terminal connection portions 70 formed by solder or welding. In addition, the two terminals 64 connected to the outer-peripheral-side wire end portions 66 are electrically connected to a power source such as an electric appliance, and thus power is supplied to both of the coils 25 through these terminals 64. The inner peripheral side wire end portion 68 of the coil 25 is exposed from the inner peripheral surface 25a of the coil, and this inner peripheral side wire end portion 68 must be connected to the terminal 64 located outside the coil 25. The inner peripheral side wire end portion 68 of the coil 25 is guided from the inner peripheral side of the coil 25 to the terminal 64 outside the coil 25 via the gap formed in the base material exposed portion 62 described above. Hereinafter, the state of the inner peripheral side wire end portion 68 of the base material exposing portion 62 will be described in detail with reference to FIG. 9. As shown in FIG. 9, the wire coil 25 and the circuit board 16 are bonded to each other via an adhesive 72. In addition, the adhesive 72 interposed between the coil 25 and the circuit board 16 is also filled in the gap between the substrate exposed portions 62. The inner peripheral side wire end portion 68 having a diameter of about 0.07 mm is extended from the inner peripheral side of the wire coil 25 to the outside of the coil 25 along the base material 50 in the base material exposed portion 62 of the polyfill adhesive 72. In this way, the inner-peripheral-side wire end portion 68 is fixed to the lower surface of the coil 25 because it is fixed by the adhesive 72 that bonds the coil 25 to the circuit board 16. The wire diameter of the wire coil 25, that is, the diameter of the inner-peripheral-side wire end portion 68, is about 0.07 mm, and is approximately the same as the gap height of the base material exposed portion 62. Therefore, the coil 25 mounted on the circuit board 16 applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) to the paper size of the substrate.

In this manner, the inner wire-side wire end portion 6 of the coil 25 is led out of the coil 25 through the base material exposed portion 62, and the coil 25 can be partially prevented from floating, while the inner portion of the coil 25 can be appropriately connected to the coil 25. The peripheral wire end portion 68 and the terminal 64. Therefore, the tilt of the coil 25 caused by the unprepared floating of the coil 25 can be avoided, and the coil 2 5 and the magnet 3 1 can be approached, which is helpful for the magnet 3 1 and the coil 25. The thickness of the brushless motor 10 having a clearance P of less than 0.5 mm is reduced. In addition, the diameter of the inner peripheral side wire end portion 68 and the height of the base material exposed portion 62 are not necessarily the same, and the base material exposed portion 62 may be formed slightly. At this time, floating of the coil 25 can also be suppressed. The wire diameter of the wire coil 25 including the outer wire end portion 66 and the inner wire end portion 6 of the coil 25 may be in a range of 0. 0 1 m m or more and 0. 1 m m or less. That is, a wire having a diameter of less than 0.01 mm is difficult to manufacture accompanying a small brushless motor. In addition, when a wire having a diameter of more than 0.1 mm is applied to a brushless motor 10, the wire coil formed by the wire ^ becomes large. With this, the size of the brushless motor 10 is increased. The miniaturization of the motor 10 is less desirable. Hereinafter, a fan motor having the same configuration as the brushless motor 10 described above will be described with reference to FIG. 10. In addition, the same reference numerals are given to the same or equivalent elements as those of the brushless motor 10, and redundant description is omitted. As shown in FIG. 10, the configuration of the brushless fan motor 80 and the housing 82 is different from the configuration of the housing 19 of the brushless motor 10. That is, the frame body 82 of the fan motor 80 is composed of a rectangular parallelepiped-shaped base member 84 having openings on the top, bottom, or sides, and an open-side square-shaped cover covering the base member 84.

Description of the invention (14) In addition, the fan motor 80 instead of the weight 3 3 has a plurality of (for example, 5) blades 88 fixed to the rotor 30 This is different from the brushless motor 10 required for vibration. The certain piece 88 is fixed to the rotor 30 or the shaft 20, and simultaneously bulges radially from the outer peripheral edge of the rotor 30 or the shaft 20. Each blade 88 rotates integrally with the rotor 30. An air introduction hole 86a is formed in the cover 86 at a position corresponding to the blade 88. Therefore, when the blades 88 are rotated integrally with the rotor 30, air is forcibly introduced into the fan motor 80 through the air introduction hole 86a. An air discharge hole 84a is formed on the lower surface of the base member 8 4 at a position corresponding to a portion where the blade 8 8 bulges. As described above, when the blades 8 and 8 are rotated integrally with the rotor 30, air is forcibly discharged from the fan motor 80 through the air discharge hole 8 4a. In the fan motor 80, a substrate exposed portion 62 is also formed on the circuit board 16 (see Fig. 9). Therefore, the inner wire-side wire end portion 6 8 of the coil 25 is led out to the outer side of the coil 25 through the substrate exposed portion 6 2 so that the coil body 2 5 body does not float up on the inner-circumference wire end portion 6 8. On the other hand, the wire end 25 of the inner circumferential side of the wire coil 25 and the terminal 64 can be connected. In this manner, the fan motor 80 can be made thinner. Although the embodiments of the brushless motor of the present invention have been described above, various vibration alarm devices that can be mounted with the brushless motor 10 are described below.
