The present invention relates to a vibration generation motor used in various mobile communication devices such as a mobile phone, and a small motor provided in a precision device. Rice field

Background art

Small motors, such as cylindrical coreless motors, are being used more frequently as devices become smaller. In particular, portable devices such as mobile phones and mopile communications, which are remarkably miniaturized, are equipped with small motors (hereinafter referred to as “vibration motors”) that vibrate the portable device itself for silent notification.

As shown in FIG. 7, the vibration motor 100 is mounted on a rotating shaft (not shown) and a housing 103 almost covering the outside of the motor driving system main body, and the rotating shaft is driven by the driving of the motor driving system main body. An eccentric weight 104 that rotates together with it, and an energizing terminal that contacts an electrode of the portable device body and supplies power to the motor drive system body.

Here, there are a variety of forms of the current-carrying terminals, and as one of them, a plate panel 105 is often used, and the elastic force of the plate panel 105 causes the plate panel 105 to itself. It is an urging force that presses against the electrodes of the portable device body. For this reason, even when soldering is not performed when assembling the portable device, the plate panel 105 and the electrode on the portable device main body continue to be in contact with each other, and the vibration motor 100 can be energized (Patent Document 1: Japanese Patent Application Laid-Open (JP-A) No. 11-1360901).

However, if the current-carrying terminals are the panel panel 105, the biasing force weakens over time, and the contact between the panel panel 105 and the electrode of the portable device body may become unstable. . To prevent this, for example, housing 1 By covering the outer circumference of 03 with an elastic body such as rubber, an elastic body is arranged between the panel panel 105 and the housing 103, and the elastic force of this elastic body acts on the panel panel 105. As a result, a long-term energizing force is secured, and the reliability of energization is improved (Patent Document 2: Japanese Patent Application Laid-Open No. 2000-078790).

In addition to the illustrated example, there is a case where a coil panel is used as a current-carrying terminal, and the coil panel is arranged so as to stand vertically with respect to the outer surface of the housing. Also in this case, the vibrating force of the coil panel serves as an urging force that presses against the electrodes of the portable device itself, and the vibration motor can be energized without soldering when assembling the portable device (Patent Document 3: Japanese Patent Application Laid-Open (JP-A) No. 11-13613 27).

However, when the panel panel 105 is used as the current-carrying terminal, the point of contact with the electrode of the portable device body is a single point, that is, a point contact. Low reliability.

Furthermore, if an elastic body is placed between the panel panel 1◦5 and the housing 103, the space efficiency will be reduced by the thickness of the elastic body, and the installation space for a small motor will be large. U.

Also, when the coil panel is used as an energizing terminal and the coil panel is erected on the outer surface of the housing, the contacts with the electrodes of the portable device body have many contacts. There is a problem with reliability. Furthermore, the longer the length of the coil panel, the larger the amount of deformation of the coil panel can be taken, but more space is required when mounting. Disclosure of the invention

An object of the present invention is to provide a motor that can improve the reliability of energization and save space.

According to a first aspect of the present invention, there is provided an exterior member (for example, a housing) that substantially covers the outside of the motor, a motor drive system main body inside the exterior member, and at least a portion exposed from the exterior member. For motor drive system A motor provided with an energizing terminal for energizing the motor drive system body with electric power supplied from the external electrode by contacting the external electrode for supplying electric power, wherein the energizing terminal is electrically conductive. The coil panel is disposed between the exterior member and the external electrode in a state where the motor driving system main body is arranged so as to be supplied with power from the external electrode. The coil panel is disposed along a portion facing the external electrode, and a part of the outer peripheral portion of the coil panel is brought into contact with the external electrode.

According to the first invention, in a state where the motor drive system main body is arranged to be supplied with electric power from the external electrode, a part of the outer peripheral portion of the coil panel is arranged to contact the external electrode. . Therefore, when the motor is fixed on the substrate on which the external electrodes are provided, the coil panel is elastically deformed by being pressed by the electrodes in the radial direction of the outer periphery of the coil panel. In other words, the coil panel elastically deforms in a direction different from the direction of expansion and contraction of the generally used coil panel itself. At this time, since the coil panel is disposed between the exterior member and the external electrode along a portion facing the external electrode of the exterior member, the plurality of winding portions of the coil panel come into contact with and contact the external electrode. The number of points can be increased, and the reliability of energization can be improved. Here, the winding part of the coilpane is one winding of the coil in which the wire is spirally wound.

This elasticity maintains the contact between the electrode of the device body and the coil panel. The coil panel has a small elasticity with time as compared to the plate panel, so it can secure the urging force against the electrode in the long term and increase the reliability of energization. Therefore, the elastic body such as rubber can be omitted, and the installation space for the motor can be reduced.

According to a second invention, in addition to the configuration of the motor according to the first invention, the coil panel is provided outside the exterior member in a state where the coil panel is not in contact with the external electrode. It is characterized in that at least a part thereof is bent or curved so as to be convex in the lateral direction.

According to the second invention, at least a part or the whole is bent or bent so that the coil panel is convex in the outward direction of the exterior member when not in contact with the external electrode. Is in a curved state. For this reason, the amount of elastic deformation in a direction different from the direction of expansion and contraction of the coil panel itself can be increased as compared with a case where the coil panel is not bent or curved. Even if the distance between the electrodes changes, it is easy to maintain the contact with the external electrode by following the change, so that the reliability of energization can be further improved.

According to a third aspect of the present invention, in addition to the configuration of the motor of the first aspect, in the state where the one end of the coil panel is separated from the outer member in a direction outside the outer member in a state of not being in contact with the external electrode. It is characterized by being arranged obliquely to the outer surface.

According to the third invention, the same effect as that of the second invention can be obtained.

According to a fourth aspect of the present invention, in addition to the configuration of the motor according to any one of the first to third aspects, the exterior member further includes a portion of the outer peripheral portion of the coil panel facing the external electrode. The coil spring is housed in an exposed state, and an insulating terminal holding portion for restricting movement of the coil panel in a direction along an outer surface facing the external electrode of the exterior member is provided. It is characterized by

According to the fourth invention, since the movement of the coil panel in the direction along the outer surface facing the external electrode of the exterior member is regulated by the terminal holding portion, the coil panel can be moved to the outer surface facing the external electrode of the exterior member. It can be prevented from bending or shifting along the direction. Therefore, the reliability of energization can be improved.

A fifth invention is the motor according to any one of the first to fourth inventions, wherein the motor drive system main body has a rotating shaft, An eccentric weight is attached to the rotating shaft, and is used as a vibration generator (vibration motor) for a portable device.

According to the fifth aspect, highly reliable energization can be obtained even for a motor, such as a vibration generator (vibration motor), for which it is difficult to obtain stable energization by vibration. Is more preferable. In addition, the installation space for the motor can be reduced, and the miniaturization of the portable device itself can be improved.

A sixth invention is characterized in that the motor according to any one of the first to fifth inventions is mounted on a portable information device such as a mobile phone. According to the sixth aspect of the present invention, a high-quality portable information device can be obtained by mounting a highly reliable motor for energization.

Furthermore, the present invention provides a motor with a brush, comprising: an energizing terminal connected to the brush; and a terminal holding portion provided on a housing of the motor with the brush, for holding the energizing terminal.

[First Embodiment]

Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

As the motor of the first embodiment, for example, a small vibration motor 1 used as a vibration device of a portable device will be described as an example.

As shown in FIG. 1, the vibration motor 1 includes a housing (exterior member) 5 that almost covers the outside of the motor, and a motor drive system main body (not shown) inside the outer member (housing 5). And a pair of coil panels (current-carrying terminals) 4 for energizing the power supplied from the electrodes (external electrodes) of the equipment body to the motor drive system body, and a motor drive system body attached to the rotating shaft. An eccentric weight 6 that rotates with movement.

Here, the main body of the motor drive system has a rotor (not shown) having a rotating shaft and a stator (not shown) provided around the rotor.

The coil panel 4 has conductivity, and as shown in FIG. 2, a coil part 4a formed so that the outer shape is bent in a state where the winding parts are in contact with each other, and a coil part 4a. A connection portion 4b extending from one end of the portion 4a and connected to the motor drive system main body via a wiring in the housing 5; Further, the connection portion 4b of the coil panel 4 may be connected to one end of the brush. Examples of the material of the coil panel 4 include stainless steel, Piano wire, and phosphor bronze.

The housing 5 has a stepped cylindrical case portion 5a that covers the front and side of the motor drive system main body with the rotating shaft penetrated, and the portion of the outer peripheral portion of the coil panel 4 facing the electrode of the device main body is exposed. And a terminal holding section 5b for accommodating the coil panel 4 in a state where the coil panel 4 is accommodated.

The terminal holding part 5b has an insulating property, and covers the rear end of the case part 5a in a substantially arch shape as viewed from the rear as shown in FIG. Part of the side of the case 5a is covered so that the bottom is flat.

The flat surface of the terminal holding portion 5b is used to facilitate installation of the vibration motor 1 on the substrate of the device main body, for example, by overlapping with the surface of the substrate of the device main body or as an indication of an installation position. I have. On one surface of the terminal holding portion 5b, two panel storage recesses 5d (shown by phantom lines) for separately storing the coil panels 4 with the notch 5c interposed therebetween are provided in the longitudinal direction and the rotation axis. It is formed in a state of being recessed in a substantially rectangular parallelepiped so that the directions are along.

When the coil panel 4 is stored in the panel storage recess 5d, the movement of the coil panel 4 in the direction along the outer surface of the housing 5 facing the electrode of the device body is restricted, and the bent portion of the coil section 4a is connected to the terminal. It protrudes from the holder 5b and is exposed. In other words, when the coil panel 4 is detached from the electrode of the device main body, the coil panel 4 is directed outward from the housing 5, that is, The housing 5 is bent so as to be convex in the radial direction.

At this time, the coil portion 4a is pressed by the electrode and is elastically deformed and pushed into the gap S, so that the outer circumference of the plurality of winding portions of the coil portion 4a is formed between the housing 5 and the electrode of the device body. Then, the housing 5 is deformed along the portion of the housing 5 facing the electrode of the device main body, and contacts the electrode of the device main body.

In addition, since the connecting portion 4b extending from one end of the coil portion 4a is connected to the power feeding portion of the motor driving system main body, it is possible to energize the motor and the external (device main body) electrode. It becomes. As described above, since there are a plurality of contacts between the coil panel 4 and the electrodes of the device main body, the reliability of energization can be improved.

As described above, according to the vibration motor 1 of the present embodiment, the coil panel 4 is held by the terminal holding portions 5b so that the direction of expansion and contraction of the coil panel 4 is along the outer surface of the motor drive system main body. Both parts of the outer periphery of the coil spring 4 are exposed from the terminal holding part 5b, so when assembling, contact the part of the outer periphery of the coil panel 4 with the electrode of the equipment body and fix the vibration motor 1 to the board. Each wound part of the coil part 4a is pressed by the electrode in a direction along the radial direction of the outer periphery of the coil part 4a and is elastically deformed. Reliability can be improved.

After the vibration motor 1 is fixed, the elastic deformation of the coil panel 4 is maintained, and the elastic force for always returning to the coil panel 4 acts on the coil panel 4. Have been. With this elastic force, the contact between the electrode of the device main body and the coil panel 4 can be maintained.

And, since the movement of the coil panel 4 in the direction along the outer surface facing the external electrode of the housing 5 is regulated by the terminal holding portion 5b, the coil panel 4 is moved along the outer surface facing the external electrode of the housing 5. It can be prevented from bending or shifting in the direction.

Furthermore, when not in contact with the electrodes of the device main body, the coil panel 4 is bent so as to be convex outward of the housing 5, so that it is not bent or bent. The elastic deformation in the direction different from the direction of expansion and contraction of the coil panel itself can be increased, and even if the distance between the housing 5 and the electrode of the device main body changes due to, for example, vibration, that change Therefore, it is easy to maintain contact with the electrodes of the device main body, and the reliability of energization can be improved.

Note that the terminal holding portion 5b may hold not only the coil panel 4 but also a brush. In this case, the connecting portion 4b of the coil panel 4 is connected to one end of the pusher held by the terminal holding portion 5b.

Furthermore, the number of contacts between the coil panel 4A and the electrodes of the device main body becomes plural, and the reliability of energization can be improved.

[Third embodiment]

A third embodiment to which the present invention is applied will be described with reference to FIG. Here, except for the parts specific to the third embodiment, the same as in the above-described first embodiment, the same parts as those in the above-described first embodiment are denoted by the same reference numerals. Description is omitted.

In the first and second embodiments described above, when the coil panel is housed in the panel housing recess, the winding portions of the coil unit are in contact with each other. In the third embodiment, a configuration will be described in which, when the coil panel is stored in the panel storage recess, the winding portions of the coil portion are spaced from each other. Specifically, the coil portion 4d of the coil panel 4B has a cylindrical outer shape before being stored. Then, as shown in FIG. 4, the coil panel 4B curves the coil section 4d so that a part of the outer periphery protrudes from the terminal holding section 5b so that the winding sections are spaced from each other. And is housed in a panel housing recess 5d (shown by a thin phantom line) of the terminal holding portion 5b. In other words, the coil portion 4d of the coil panel 4B is stored in the panel storage recess 5d while maintaining elastic deformation.

Then, when attaching the vibration motor 1B to the board of the equipment main body, a part of the outer periphery of the coil part 4d protruding from the terminal holding part 5b is brought into contact with the electrode of the equipment main body, thereby making the motor drive system To the power supply.

Is connected to and energized.

While the electrodes of the device body are in contact with the plurality of winding portions of the coil portion 4d, they press these winding portions and push the coil portion 4d into the gap S2. After that, if the vibration motor 1B is fixed to the board, the coil section 4d attempts to elastically return, so that the contact between the board and the coil panel 4B is always maintained.

[Fourth embodiment]

A fourth embodiment to which the present invention is applied will be described with reference to the drawing of FIG. Here, the parts other than the parts specific to the fourth embodiment are the same as those in the above-described first embodiment, and the same parts as those in the above-described first embodiment are denoted by the same reference numerals. Description is omitted.

In the third embodiment, the coilpane is bent or curved so as to protrude outward from the housing when it is detached from the electrode of the device main body. However, in the fourth embodiment, the configuration is such that, when not in contact with the electrodes of the device main body, one end of the coil panel is disposed obliquely with respect to the outer surface of the housing so as to separate in the outward direction of the housing. Will be described.

Specifically, the coil part 4 e of the coil panel 4 C is The external shape is formed in a cylindrical shape. As shown in FIG. 5, the coil panel 4C has a panel housing recess 5e (a thin wire) in which one end is inclined away from the outer peripheral surface of the housing 5 to the outside than the other end. The outer periphery of one end of the coil panel 4C protrudes from the terminal holding portion 5b.

The inner surface F of the panel housing recess 5e that comes into contact with the tip of the coil panel 4C is inclined so that elastic deformation can be performed smoothly. That is, when fixing the vibration motor 1C to the substrate of the device body, the vibration motor 1C is pressed. At this time, the coil portion 4e of the coil panel 4C is pressed by the electrode of the device main body, and the tip of the coil portion 4e is elastically deformed along the inner surface F while being pushed into the gap S3, The electrode of the main body comes into contact with the multiple windings of the coil 4e. Even after the vibration motor 1C is fixed to the board, the coil section 4e tries to return elastically, so that the contact between the board and the coil panel 4C is always maintained.

Here, the same method as in the first to third embodiments is used for energization of the electrodes of the device main body and the motor drive system main body.

In the present embodiment, the coil panel 4C of the coil panel 4C has a cylindrical outer shape, but the coil panel 4C may be formed in a state where the coil section is inclined beforehand. good. Further, it is preferable that the inclination angle の between the axial direction (dotted line) of the coil panel 4C and the electrode 7 of the substrate of the portable information device is 45 ° or less.

[Fifth embodiment]

A fifth embodiment to which the present invention is applied will be described with reference to FIG. Here, the parts other than the parts specific to the fifth embodiment are the same as those in the above-described first embodiment, and the same parts as those in the above-described first embodiment are denoted by the same reference numerals. Description is omitted.

In the above-described fourth embodiment, the configuration in which the coil panel is deformed toward the gap below the coil portion when the vibration motor is installed on the substrate of the device main body is exemplified. Department facing The direction in which the coil panel is deformed is not limited as long as the coil panel is disposed along the same direction. In the fifth embodiment, a configuration in which each winding portion of the coil panel is deformed obliquely will be described.

Specifically, as shown in FIG. 6 (a), the coil panel 4D includes a coil portion 4f having a cylindrical outer shape when no load is applied, and a connection portion 4f extending from one end of the coil portion 4f. b and a fixed portion 4 g extending from the other end of the coil portion 4 f. The coil panel 4D is housed in the panel housing recess 5f (illustrated by a thin virtual line) such that a part of the outer periphery of the coil section 4ί projects from the terminal holding section 5b, and the fixing section 4g is mounted. When fixed to the terminal holding portion, a gap S4 is formed at the front and rear of the coil portion 4f in a state where the lower portion of the coil portion 4f is in contact with the bottom of the panel housing recess 5 #.

When the vibration motor 1D is attached to the board of the equipment main body in this state, a part of the outer periphery of the coil panel 4D protruding from the terminal holding part 5b contacts the electrode of the equipment main body, and power is supplied to the motor drive system main body. It becomes possible. At this time, when the vibration motor 1D is pressed against the substrate of the device main body, the electrodes of the device main body come into contact with and press the plurality of winding portions of the coil portion 4d. As a result of this pressing, the coil portion 4f is obliquely fc deformed as shown in FIG. 6 (b), and is pushed into the gap S4 while being inclined. At this time, one end of the coil part 4 f leans against the chamfered part C of the panel storage recess 5 f.

After the vibration motor 1D is fixed to the board, the coil section 4f tries to return elastically, so that the contact between the board and the coil panel 4D is always maintained. Here, the same method as in the first to fourth embodiments is used for energization of the electrodes of the device main body and the motor drive system main body.

As described above, in the fifth embodiment, the gap S4 is formed in front of and behind the coil portion 4f of the coil panel 4D, so that a gap is formed below the coil portion 4f. In comparison, the depth of the coil panel storage section 5f can be reduced, and the terminal holding section 5b can be reduced in size. Therefore, space saving of the vibration motor can be improved. It is needless to say that the present invention is not limited to the above embodiment, but can be appropriately changed.

For example, in the fifth embodiment, the coil panel is arranged so that the direction of expansion and contraction of the coil panel extends along the direction of the rotation axis of the motor drive system main body, but the direction of expansion and contraction of the coil panel relative to the outer surface of the housing. If the coil panel is not perpendicular to the outer surface of the motor drive system main body, the coil panel may be arranged in any state unless the coil panel is set upright. The coil panel may be arranged on the outer surface of the motor drive system main body along the circumferential direction of the motor drive system main body.

In addition, in order to smoothly perform elastic deformation due to contact with the electrodes of the device main body, it is preferable to increase the gap between the winding portions of the coil panel. In order to make contact with many contacts, it is preferable to reduce the gap between the winding portions of the coil panel. The gap between the winding portions of the coil panel may be a state where there is no load when no load is applied, that is, a state where the winding portions are in contact with each other.

Further, as the outer diameter of the coil spring 4 is reduced, the depth of the panel housing recess 5d can be reduced, and the size of the terminal holding portion 5b can be reduced. That is, the force S can reduce the installation space of the vibration motor 1. Industrial applicability

According to the present invention, since a plurality of winding portions of the coil panel come into contact with an external electrode to form a plurality of contacts, the reliability of energization can be improved. In addition, since an elastic body such as rubber can be omitted, the installation space for the motor can be reduced.
