Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an impact vibration generator,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an impact vibration generating apparatus, and more particularly, to an impact vibration generating apparatus capable of precisely controlling shock vibrations and generating various types of signals and communication interfaces between users and various devices such as multimedia devices, game devices, The present invention relates to an impact vibration device that can be utilized as an impact vibration device.

Generally, the vibration generating device is embedded in an electronic device such as a mobile phone, for example, and performs a function of notifying the arrival of an incoming call or a short message by vibration instead of a bell sound. So that the user can feel a sense of reality to increase the enjoyment or interest.

Also, thanks to the development of technology, it has become possible to enjoy not only communication but also multimedia reproduction, transmission and reception, internet, games, With the game machine, it is possible to play the Internet or video; The video player can also play music, videos, Internet and games. Most of these devices are built with a vibration generating device, which is intriguing, and a conventional vibration generating device mainly uses a small vibration motor. Conventional vibration motors include a single-piece motor disclosed in Korean Patent No. 0389631, a reciprocating linear motion type single-phase motor disclosed in Korean Patent Laid-Open Publication No. 2005-0122101, a rod-shaped motor, And vibration is generated by the vibration generated by the rotation or the vibration caused by the reciprocating motion of the weight in the resonance region. However, in the vibration control in the conventional vibration motor as described above, the rotation speed change by the voltage adjustment or the vibration on / off by the power on / off is used, It is difficult to adjust the generation cycle of the vibration or the frequency of occurrence of the vibration, and there is also a disadvantage that the remaining vibration gradually disappears even after the power is cut off. In addition, it is difficult to generate a single vibration, and it is difficult to make a sharp and strong momentary vibration such as an impact vibration.

In order to solve such a problem, Korean Patent Laid-Open Publication No. 10-2013-0133651 discloses an apparatus for generating an impact vibration, comprising: a fixing portion having a hole formed therein and having a coil disposed on an outer periphery thereof; A rotating part having a rotating shaft disposed in an inner hole of the fixing part and a magnet provided on an inner circumferential surface, the rotating part surrounding the fixing part, the center part being connected to the rotating shaft and rotating with respect to the fixing part; At least one protrusion attached to one end of the rotation part and rotating together with the rotation part; And at least one stopper that contacts the projection when the rotation unit rotates to obstruct the rotation of the rotation unit. According to such an impact vibration generating apparatus, sharp and strong impact vibration (Impactive Vibration) is generated by using a principle in which an impact is generated in proportion to the speed and weight of a moving object when a moving object contacts with another object at a speed A single impact vibration or a small number of shock vibrations can be generated and a strong vibration due to continuous shock vibration can be generated.

However, as shown in Figs. 1 and 2, after the protrusion 100 and the stopper 101 collide with each other due to the rotation of the rotation part in the counterclockwise direction, the rotation of the rotation part in the clockwise direction To stop the rotation part, the projection of the rotation part stops at an arbitrary position. When the rotation part is rotated counterclockwise at an arbitrary position to collide with the rotation part, the larger the rotation angle, the larger the amount of impact vibration becomes. In Fig. 1, when the projections start at the positions of D, E and F, the magnitude of the shock vibration becomes D> E> F. For example, if the protrusion and the stopper collide with each other due to rotation in the counterclockwise direction at the position of F and the vibration is generated, the shock vibration amount is small and it may be difficult to obtain utility. Particularly, when a single vibration is generated, it can be felt that a short vibration does not occur. In such a conventional shock vibration device, when the protrusion and the stopper collide with each other to generate vibration, and when the rotation part is stopped by interrupting the power source while the rotation part is rotating in the clockwise direction in the opposite direction, A variation occurs depending on the state of the rotor or the state of the vibration device, and it is difficult to uniformly position the projections. In addition, even if it is placed at a specific position, it is difficult to keep the rotor at a desired position because the rotor is easily moved due to a fine impact or a change in posture of the vibration device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

First, an embodiment of an impact vibration generator in which the length of a gap between a magnet and a winding core is changed according to the present invention will be described.

3 is a schematic cross-sectional view illustrating an inner rotor type impact vibration generator according to an embodiment of the present invention. For the sake of understanding, FIG. 4 illustrates a configuration diagram based on a cross section taken along line A-A 'of FIG.

In the inner rotor type shock-absorbing vibration generating device of Fig. 3, the magnet is provided on the fixed portion, and the coil is provided on the rotating portion that rotates with respect to the fixed portion. The inner rotor type shock-absorbing device of FIG. 3 includes a rotary shaft 85; A rotating portion 82 integrally coupled to the rotating shaft 85 disposed at the center and having a coil 86 disposed around the rotating shaft 85 and rotating; A fixing part surrounding the rotation part and provided with a magnet for supporting the rotation axis and forming a magnetic pole; At least one projection (89) attached to one end of the rotation part (82) and rotated together with the rotation part (82); And at least one stopper (97) which collides with the protrusion (89) when the rotation part rotates with respect to the fixed part and interrupts the rotation of the rotation part, and the magnet (93) of the fixed part and the rotation part Air gaps are formed between the cores 87 in which the coils 86 are wound, and the length of a portion of the gap is formed differently. It is preferable that the magnet 93 is provided as a permanent magnet, but it may be provided with an electromagnet in which a coil is wound. The commutator 88 may be disposed on the outer circumference of the rotary shaft 85 so as to be concentric with the rotary shaft 85 and the commutator 88 may be configured to apply a current to the coil 86. [ And is rotatable together with the coil (86). It is preferable that the coil 86 is wound around a winding core 87 which is a magnetic body for supporting the coil 86 so as to increase the magnetic efficiency. However, in order to reduce the cost and miniaturize the winding 86, May be omitted or may be provided with a non-magnetic material. Since the protrusion 89 is configured to rotate with the rotation unit, the protrusion 89 may be coupled with other components that can rotate. For example, the projection may be provided on the rotary shaft. Further, the support plate 96, which will be described later, is provided with at least one stopper 97 so as to collide with the projections 89 and to interfere with the rotation of the rotation unit. At this time, the protrusions 89 may be provided so as not to be rotated by 360 degrees or more. The stopper 97 may be integrally formed by deforming the brush holder 95, the frame 92, or a part of the support plate 96. The stopper 97 is not limited to a specific position and may be provided to interfere with the rotation of the rotation part together with the projection 89 when the rotation part 82 rotates. However, the protrusion 89 should be separated from the stopper 97.

As described above, the fixing portion supporting the rotation shaft 85 and including the magnet may include a frame 92. More specifically, a frame 92 is provided which is capable of forming a space therein to enclose the rotary part 82 and to support the rotary shaft 85 at one end thereof, and a magnet 93 is mounted on the frame 92 Lt; / RTI > Preferably, the magnet 93 is coupled to the inner circumferential surface of the frame 92 so as to surround the rotating portion. Here, the air gap (a 1 ~ a. 3) is formed, Figure 3 and has the winding core and the magnet if a coil is wound around the winding core, as the example shown in Figure 4 between the magnet 93 and the coil A gap is formed. As it is shown in Figure 4, by deforming the portion of the core 87 facing the magnet 93, and constitutes a different effective length of the air gap (1 a) by modifying a part of the air gap. As described above, by deforming a part of the gap and configuring the length of the effective gap differently, the magnetoresistance in the magnetic circuit formed between the core and the core in which the gap having the different effective length is located is deformed.

The magnetoresistance Rm in the magnetic circuit can be calculated by the following equation (1).

Rm = ℓ 1 / μS + ℓ 2 / μ 0 S ------------------------------------- (One)

Here, ℓ 1 is the length (m) of the magnetic circuit, ℓ 2 is the length (m), S is the cross-sectional area of the magnetic circuit of the air gap (㎡), μ is the magnetic permeability of the magnetic circuit (H / m), μ 0 is the vacuum magnetic permeability (H / m).

As can be seen from the above formula (1), since the magnetic resistance Rm in the magnetic circuit is proportional to the length ( 2 ) of the gap, when the length of the gap in the magnetic circuit is increased, And the magnetic flux forms a magnetic circuit with a tendency to minimize magnetic resistance.

Accordingly, as shown in Figure 4 when forming large a part length of the gap (a 1), the lines of magnetic force generated in the magnetic circuit, is difficult to pass through the length of tonghayeoseo the magnetic material of the larger pore side, the length of the intact air gap side The rotating body is pulled and rotated (rotated in the direction of B - > C in Fig. 5) due to the force that more magnetic lines of force are to pass through. Therefore, the rotating portion rotates with respect to the fixing portion so that the corresponding position of the fixing portion corresponding to the position of "A" of the core 87 constituting the rotating portion becomes B at C. In this case, the C position at which the " A "of the rotating portion is rotated and stopped from the B position is determined by the magnetic force distribution formed between the winding core 87 and the magnet 93 in which the deformed gap a 1 is located.

The position of "A" of the winding core 87, which is a rotor, of the rotor is set to be a stator Quot; C "position of the magnet 93. [ Therefore, for example, in an impact vibration generating apparatus in which the length of a specific gap is different in the gap between the coils wound with the coils constituting the rotor and the magnets constituting the stator, the projections of the impact vibration generating apparatus collide with the stoppers, By disposing the protrusion at a position where the maximum amount of impact can be obtained by the characteristics of the magnetic circuit when the rotating part is stopped by interrupting the power supply while the rotating part is rotating in the counterclockwise clockwise direction after occurrence of the shock, When the vibration generator is stopped, the protrusion is automatically returned to the correct position, thereby improving the performance of the vibration generator.

The inner rotor type impact vibration generator according to an embodiment of the present invention shown in FIG. 3 can be used for generating continuous shock vibration in addition to generating a short shock vibration according to the purpose of use.

In addition, a bearing 91 having a hole into which the rotation shaft 85 is inserted may be provided therein. The bearing 91 may be coupled to one end of the frame 92 to support the rotation shaft 85. The bearing 91 may be formed in the frame 92 to reduce the cost, As shown in FIG. The brushes 94 are provided in at least one pair and are provided with brush holders 95. The brushes 94 are provided on the brushes 94 and the bristles 94, It is preferable to fix it. The brush holder 95 may be coupled to the frame 92 or may be coupled to a support plate 96, described below. In addition, when the support plate 96 capable of supporting the rotation shaft 85 is provided, the rotation shaft 85 may be coupled with the frame 92 to form an internal space. The bearing 91 may be disposed at a central portion of the support plate 96 supporting the rotary shaft 85.

The rotation shaft 85 disposed at the center of the rotation part is rotatably supported by the frame 92 and the rotation part is rotated by the rotation part such that the magnet 93 and the coil 86 face each other, And the brush 94 can be engaged with the commutator 88 so as to be in sliding contact with each other.

The bearing 91 may be housed in the frame 92 and the support plate 96, or may include a separate bearing housing.

FIG. 6 shows an outer rotor type impact vibration generator according to an embodiment of the present invention. As shown in the cross-sectional view of FIG. 7, a part of the gap length may be different. 6 shows the configuration of the inner rotor type impact vibration generating device shown in Fig. 3 as a whole except that the coil 78 is provided on the fixed portion and the magnet 73 is provided on the rotating portion that rotates with respect to the fixed portion The detailed description of the outer rotor type impact vibration generating apparatus of FIG. 6 will be omitted. Fig. 7 is a cross-sectional view showing a relative motion relationship between the core and the magnet due to the characteristics of the magnetic circuit between the core wound with the coil and the magnet disposed around the core in the shock vibration generator of Fig. The operation of the part of the gap length in the impact vibration generating apparatus shown in Fig. 7 according to different structures is the same as that of the impact vibration generating apparatus of Figs. 4 and 5, and therefore, detailed description about Fig. 7 is omitted. The outer rotor type impact vibration generator according to an embodiment of the present invention shown in FIG. 6 may be used for generating continuous shock vibration in addition to generating a short shock vibration according to the purpose of use.

8 illustrates another embodiment of the outer rotor of the shock-and-vibration generating apparatus according to the present invention. In the embodiment shown in FIG. 6, the cover 121 surrounding the rotating portion is provided. 6, the detailed description of the outer rotor type impact vibration generator of FIG. 8 will be omitted. However, as illustrated in FIG. 8, the circuit board 124 may be provided around the holder 130, and the circuit board 124 may include a driving circuit for rotating the rotating unit. In addition, the circuit board 124 may include a magnetic pole position detecting element such as a Hall element such as a Hall element to constitute a circuit for controlling the current of the coil 125. However, the circuit board 124 may be separately provided outside the impact vibration generating device.

Fig. 9 is a cross-sectional view showing the relative motion relationship between the core and the magnet due to the characteristics of the magnetic circuit between the core wound with the coil and the magnet arranged to surround the core in the shock vibration generator of Fig. 8; As described above with reference to FIGS. 4 and 5, since there is a property of maintaining the position where the magnetoresistance between the winding core and the magnet is minimized due to the characteristics of the magnetic circuit, the magnets 127, Quot; A "of the winding core 126 which is the stator. Therefore, by arranging the protrusion at a position where the maximum amount of impact can be obtained, when the shock vibration generator is stopped, the protrusion is always automatically returned to the fixed position, so that the performance of the shock vibration generator can be improved.

Next, an embodiment of an impact vibration generating apparatus provided with a positioning magnet according to the present invention will be described.

11 is a view schematically showing a cross section of an apparatus of an embodiment having a positioning magnet in an outer rotor type impact vibration generating apparatus of the present invention.

The outer rotor type impact vibration generating apparatus of FIG. 11 has a structure similar to that of the outer rotor type impact vibration generating apparatus of FIG. 7 described above, but the positioning magnet is separated from the magnet provided at the rotating portion and provided at the stationary portion.

10, when the rotating part in which the magnets are arranged is intended to stop after rotating to some extent in the clockwise direction, the positioning magnet 301 disposed on the fixed part and the magnet 201 disposed on the rotating part are arranged in the same N pole So that the pushing force acts on each other, so that the rotating part keeps rotating in the clockwise direction (a- > b direction). This force acts on the position-setting magnet 301 of the fixed portion and the magnet 201 of the rotating portion to have different magnetic poles and to the point where a pulling force acts on each other. Fig. 11 shows a state in which, in the impact vibration generating apparatus of Fig. 10, the protrusions are aligned to positions capable of generating the maximum amount of impact by the interaction of the magnets of the positioning magnet and the rotor of the stator.

Since the position of the rotary part can be moved from a to b by using the characteristics of such magnets, the specific position of the rotor can be matched to the specific position of the stator even if there is some external influence on the shock vibration generator. Therefore, in the case of the impact vibration generating apparatus equipped with the positioning magnet, when the protrusion and the stopper of the impact vibration generating apparatus collide with each other to generate vibration, the power is cut off while the rotating unit is rotating in the clockwise direction , The projections are arranged at positions where the maximum amount of impact can be obtained by the characteristics of the magnets as described above. Therefore, when the shock vibration generator stops its operation, the projections are always automatically returned to the fixed positions, Performance can be improved.
