Recently, in order to increase the driving feeling of the driver, a method of transmitting a part of the noise generated from the engine of the car to the driver has been sought. In particular, when the hybrid vehicle or the electric vehicle is driven by using the output of the motor without utilizing the output of the engine, the engine noise and vibration amount are significantly reduced, which causes the driver to significantly reduce the speed or the driving feeling.

Accordingly, there is a vehicle virtual engine sound generator 1 shown in FIGS. 1 and 2 as a way that the driver can hear and feel according to the acceleration pedal manipulated by the driver. According to this, the elastic support 20 is installed in the housing space of the casing 10, the current to which the vibrator 40 supported by the elastic support 20 is applied to the coil 30 through a current supply line (not shown). By vibrating according to the signal, vibration and noise are generated while the vibrator 40 vibrates.

At this time, the vibrator 40 is formed of a large mass in order to lower the resonant frequency and is fixed by the position fixing protrusion 22 of the elastic support 20 to apply the current waveform to the coil 30 through the current supply line. In accordance with the principle of electromagnetic induction. The coil 30 is mounted to be in contact with the inner surface of the inner ring 20b shown in FIG. 2 so that a current supply line (not shown) is introduced into the casing 10 through the inlet 13 so that the coil 30 and Connected.

The elastic support 20 is composed of an outer ring 20a and an inner ring 20b, and a connecting elastic body 21 is formed therebetween. Accordingly, when the vibrator 40 vibrates in the vertical direction by the coil 30, the vibrator 40 is allowed to vibrate up and down by the elasticity of the connecting elastic body 21. The vibration of the vibrator 40 is one end of the connecting bolt 15 of the casing 10 is fixed to the vehicle body is transmitted to the vehicle body can be felt by the driver, the sound generated from the vibrator 40 is also transmitted to the outside to the driver You will hear it. Although not shown in the figure, one side opening of the casing 10 is covered by a lid to act as a module.

The conventional vehicle virtual engine sound generator 1 configured as described above may have the vibrator 40 in various forms according to the waveform of the current transmitted through the current supply line, thereby simultaneously emitting the desired vibration and sound. .

However, the conventional vehicle virtual engine sound generator 1 shown in Figs. 1 and 2 is mounted on the inner ring 20b of the elastic support 20 in which the coil 30 vibrates up and down, and this coil 30 As the current supply line for transmitting the current signal to the coil is formed to extend to the coil 30 through the elastic support 20 up and down with the vibrator 40, the noise in the current signal line connected to the coil 30 As a result, there are limitations in controlling sound and vibration as intended, and there is a problem in that the endurance life of the current signal line is lowered.

As shown in the figure, the vehicle virtual engine sound generating apparatus 100 according to the first embodiment of the present invention, the housing space 110a having one side open and the elastic mounting portion 116 therein the casing 110, the cover 120 covering the opening of the casing 110, the coil 130 mounted on the step 118 of the casing 110, and the housing space 110a of the casing 110. It consists of a vibrator (140, or yoke) mounted on the elastic mounting portion 116 and the lower cover 150 for sealing the lower opening of the casing 110.

As shown in FIG. 7, the casing 110 has an opening formed at an upper side thereof, and an elastic holder 116 for mounting the vibrator 140 is formed at a lower side of the accommodation space 110a. Since the elastic holder 116 is connected to only the plurality of connecting elastic bodies 119 from the body of the casing 110, the elastic holder 116 is allowed to be displaced in the vertical direction with respect to the body of the casing 110. Here, the connecting elastic body 119 is formed of a curved plate, and connects the body of the elastic mounting portion 116 and the casing 110, but the elastic spring portion 116 serves to allow a sufficiently large vertical displacement Do it.

A ring-shaped position protrusion 112 is formed around the elastic mounting portion 116, and the position of the vibrator 140 is inserted while the protrusion 141a of the first vibrator 141 located on the lowermost side of the vibrator 140 is inserted. Is correctly aligned with respect to casing 110. In the drawing, although the configuration of the position projection 112 of the elastic mounting portion 116 is an example of the ring shape, the present invention, if the first vibrator 141 can be fixed to the position of the protrusion 141a in a plurality of positions It includes all forms of arrangement or mutual irregularities.

The upper end of the casing 110 is formed with a step 118 for fixing the position of the coil 130. The diameter of the step 118 is formed to be slightly larger than the diameter of the fixing plate 131 of the coil 130 or within an allowable tolerance range. Accordingly, when the fixing plate 131 of the coil 130 is mounted on the step 118 of the casing 110, the center of the coil 130 is aligned with the center of the vibrator 140 within an allowable range. The micro gap between the coil 130 and the vibrator 140 may be easily matched.

A connecting passage 113 is formed at the side surface of the casing 110 to communicate with the accommodation space 110a. As a result, the current supply line 99 does not pass through the vibrator 140 or the elastic support 116 to the coil 130. It is directly connected.

The cover 120 is used to close the opening of the casing 110 to complete the assembly. The cover 120 is formed with a connection bolt 125 connected to the vehicle body, and transmits the sound and vibration generated by the vibration of the vibrator 140 to the vehicle body.

When the cover 120 is coupled to the casing 110 while the coil 130 is mounted on the step 118 of the casing 110, the bottom surface of the cover 120 is connected to the fixing plate 131 of the coil 130. It adheres to the upper surface. Accordingly, the position of the coil 130 is fixed in the up and down direction, so that the coil 130 may be positioned at one position in the casing 110 even when the device 100 is installed upside down. At this time, the bottom surface of the cover 120 may be formed as a flat surface to be in close contact with the fixing plate 131 of the coil 130, the recessed surface for receiving the fixing plate 131 on the bottom surface of the cover 120 128 may be configured such that the recessed surface 128 is in close contact with the upper surface of the fixing plate 131.

The coil 130 is formed of a fixing plate 131 fixed to the casing 110 and a bobbin 132 wound with a plurality of wires. The wire wound on the bobbin 132 is connected to a current supply line 99 connected from the outside, and current is supplied to the wire wound on the bobbin 132 according to a current waveform applied from a controller not shown in the drawing.

The coil 130 is spaced apart from the vibrator 140 and the elastic mounting portion 116 swinging up and down, and is fixed to the step 118 of the upper end of the casing 110 body independent of these (140, 116), As in the conventional coil (30 of FIG. 1), the phenomenon of noise is minimized as the rocking occurs. In addition, the current supply line 99 for supplying current from the control unit to the coil 130 is directly fixed to the upper casing 110 through the connection passage 113 of the casing 110 as shown in FIG. Since it is directly connected to the coil 130, the current supply line 99 is also connected to the coil 130 in place irrespective of the vibrator 140 and the elastic mounting portion 116 also swings up and down.

Thus, although the current supply line in the conventional apparatus 1 is connected to the coil 30 through the vibrator 40, the repetitive load due to the up and down oscillation acts, but the apparatus 100 according to the present invention has a current supply line. Since the 99 is positioned at a constant posture and does not oscillate, the life of the current supply line 99 can be sufficiently long while minimizing noise generated in the current supply line 99.

As shown in the drawing, the vibrator 140 is formed by stacking a lower first vibrator 141, an intermediate second vibrator 142, and an uppermost third vibrator 143. The vibrator 140 is arranged with a minute gap between the coil 130 and is relatively large in weight to lower the resonance frequency.

A female screw portion is formed below the vibrator 140, and the vibrator 140 and the elastic mounting portion 116 are integrated with the bolt 66 passing through the bolt hole 116a formed in the elastic mounting portion 116. As a result, the vibration of the vibrator 140 is not interfered with the vibration of the elastic holder 116 according to the current waveform applied to the coil 130, and the vibration of the vibrator 140 can be accurately controlled according to the current waveform. have.

The lower cover 150 has a coupling jaw 151 engaged with the catching jaw 114 of the casing 110 in order to be coupled to the casing 110 within a predetermined tolerance in a predetermined posture.

The casing 110, the cover 120, and the lower cover 150 are coupled through one long fixing bolt 55. To this end, the casing 110 has holes 55a penetrating in the vertical direction at intervals of 120 degrees, and the cover 120 and the lower cover 150 also have holes 22a and female threads aligned with the holes 55a. A ball 88a is formed, and the assembly is completed by penetrating through these 22a, 55a, 88a with the fixing bolt 55.

Hereinafter, the vehicle virtual engine sound generating apparatus 200 according to the second embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, in describing the second embodiment of the present invention, the same or similar reference numerals are given to the similar components to those of the above-described first embodiment, and detailed descriptions thereof are omitted to clarify the gist of the second embodiment. Let's do it.

9 is an exploded perspective view of a vehicle virtual engine sound generating apparatus according to a second embodiment of the present invention, FIG. 10 is a cutaway perspective view of the vehicle virtual engine sound generating apparatus of FIG. 9, and FIG. 11 is a vehicle virtual engine sound generating apparatus of FIG. 9. The assembly sequence of FIG.

As shown in the figure, the vehicle virtual engine sound generating apparatus 200 according to the second embodiment of the present invention, the housing space 210a having one side open and the elastic mounting portion 216 is formed inside the casing 210, a cover 220 covering the opening of the casing 210, and a step 220 mounted on the step 218 of the casing 210 to be guided into place, and insert injection processing is performed on the cover 220 to cover the cover 220. The lower side sealing the coil 230 integrated with the lower side, the vibrator 140 or the yoke mounted on the elastic mounting portion 216 in the housing space 210a of the casing 210, and the lower opening of the casing 210. It consists of a cover 150.

That is, as shown in Figs. 9 to 11, in the second embodiment of the present invention, the coil 230 is integrated with the lid 220, and the coil 220 is fixed to the casing 210 while the coil 220 is positioned at the same time. The position of 230 is different from that of the above-described first embodiment in that it is configured to be spaced apart from the vibrator 140 by a predetermined fine gap.

Through this, according to the second embodiment of the present invention, as the insert 230 is integrally formed with the coil 230 and the cover 220, the casing 210 is fitted while matching a minute gap between the coil 230 and the vibrator 140. The vibrator 140, the coil 230, and the like can be more easily aligned to obtain an advantage that can be assembled. In addition, the coil 230 is integral with the cover 220 while the fixing plate 231 of the coil 230 is bent so that the insert 230 can be integrally inserted into the cover 220, and the center portion of the fixing plate 231 is connected to the connecting bolt ( As it is configured to be caught by the head of 125, the structural rigidity of the coil 230 and the cover 220 can be obtained to be more excellent and robust.

Meanwhile, in the second embodiment of the present invention, the connecting passage 223 of the current supply line for supplying the bobbin 232 of the coil 230 is formed in the cover 220 instead of being formed in the casing 210. In this way, the cover 220 and the coil 230 and the current supply line connected thereto become one module, which facilitates the management of parts and significantly lowers the possibility of short-circuit such as a current supply line that may occur in the assembly process. Advantageous effects can be obtained.

In the present invention configured as described above, the vibrator 140 is located in the elastic mounting portions 116 and 216 under the casing 110 and 210, and the coils 130 and 230 having the vibrator 140 are elastic mounting portions ( The fixing plates 131 and 231 are mounted on the steps 118 and 218 of the upper ends of the casings 110 and 210 spaced apart from the 116 and 216 so that the vibrations of the vibrator 140 are affected. The coils 130 and 230 can be positioned without fluctuation without receiving them, and at the same time, the fluctuations of the current supply line 99 supplied to the coils 130 and 230 can be suppressed and used for the excitation of the vibrator 140. By minimizing the amount of noise generated in the resulting current waveform, not only can the oscillator be accurately vibrated at the intended amplitude and frequency, but also the current supply line 99 is kept unstable. Therefore, it is possible to remarkably reduce the possibility of breakage due to wear of the current supply line 99, thereby obtaining an advantageous effect of realizing a sufficiently long service life.

In this way, the present invention can generate a current waveform applied to the coil (130, 230) in the control unit according to the signal by the acceleration pedal manipulated by the driver to accurately control the amplitude and frequency of the vibrator 140 for a long time In addition, the advantage of giving the driver a sound and vibration to feel the active driving feeling is obtained to make the driving fun more feel.

In the above, the preferred embodiments of the present invention have been described by way of example, but the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope described in the claims.
