Description

Knob for shift lever of vehicle {KNOB FOR GEAR SHIFT LEVER OF VEHICLE}

The present invention relates to a knob for a shift lever of a vehicle.

In general, an automatic transmission has the advantages of smooth acceleration and deceleration of a vehicle because the rotational force of the engine is transmitted through a fluid, so that the ride comfort is good, and since no load is directly applied to the engine, it protects the engine and extends the life of each part. Because of this, it is widely used in vehicles.

In addition, the shift lever for operating the automatic transmission is usually mounted on the interior panel of the vehicle and changes the shift mode of the automatic transmission to parking mode (P), reverse mode (R), neutral mode (N), and driving mode (D). function to

Meanwhile, an indicator lamp is installed on a dashboard of a vehicle equipped with an automatic transmission so that a user can identify a current shift mode. The indicator lamp consists of four indicators such as parking mode (P), reverse mode (R), neutral mode (N), and driving mode (D).

However, in the case of the prior art, there is a problem in that the user has to directly look at the shift lever or directly check the indicator light on the instrument panel in order to recognize the current shift mode.

On the other hand, Registration No. 10-2005-16267 (Haptic shift device for automatic transmission) registered with the Korean Intellectual Property Office is a haptic device that operates P, R, N, D, and manual operation modes through the main shift knob. Disclosed is a technology for transmitting a feeling of operation through a motor when shifting gears using technology. This prior art, as described in claim 1, the main speed rotary knob rotatable in both directions to change the operating mode; a position sensor detecting an operation mode indicated by the main speed rotation knob and outputting a position signal corresponding thereto; an electronic control unit that calculates the magnitude and direction of rotational force applied to the rotation knob of the main gear from the change in acceleration of the position signal and outputs a motor control signal according to the magnitude and direction; and a rotation motor providing a feeling of operation to the main speed change rotary knob when the operation mode is changed according to the motor control signal. Therefore, in the prior art, since the rotation motor provides a feeling of operation to the main shift rotary knob when the operation mode is changed, the aforementioned problems can be solved.

However, in the prior art, since the rotary motor transmits vibration to the entire main shift rotary knob, the entire gear lever box vibrates, and heat generated by repetitive vibration during driving cannot be smoothly dissipated, and power is supplied to the rotary motor. There is a problem that the terminal to apply is formed of a wire and is short-circuited by vibration.

In particular, since the current state of the shift mode is notified only by vibration, it is not efficient, and furthermore, it can be applied only to a dial-type shift device, and there is a problem in that the application is limited to a stick-type shift lever.

In addition, there is also a problem in that the distance between the rear side obstacle and the vehicle cannot be confirmed by vibration when the vehicle is reversing.

That is, the vibration speaker 20 emits vibration, sound, or voice set for each shift mode. For example, when the shift lever is operated to the reverse or parking position, the vibration speaker 20 emits a short sound such as "ding-dong, ding-dong" or a voice such as "reverse" or "parked" along with a short vibration. can radiate

For example, the vibration speaker 20 emits vibration when a frequency of 500 Hz or less is input through the control unit 40, and outputs sound or voice when a frequency of 1 KHz or more is input. Since the vibration of the vibration speaker 20 or emission of sound or voice is a common technique that can be easily understood by those skilled in the art, a detailed description thereof will be omitted.

As shown in FIGS. 1 and 3 , the light generator 30 is installed on the circuit board 31 embedded in the knob body 10 to generate light inside the knob body 10 . That is, the light generator 30 emits illumination light inside the knob body 10 . When the knob body 10 is made of a material such as acrylic or plastic capable of transmitting light, the light generator 30 directly transmits illumination light through the knob body 10 to provide illumination light to the outside of the knob body 10 .

The light generator 30 emits illumination light set for each gear shift mode in the same manner as the vibration speaker 20 described above. For example, the light generator 30 may blink the illumination light briefly or blink long when the shift lever is operated to the reverse or parking position, and otherwise turn on or blink the red illumination light or the blue illumination light. To this end, the light generator 30 is provided with a plurality of LED elements 32 emitting light of different colors.

The control unit 40 controls the operation of the vibration speaker 20 and the light generator 30 according to the shift mode of the transmission to generate set vibration, sound or light according to the corresponding shift mode. As shown in FIG. 7 , the control unit 40 is generally directly electrically connected to a shift stage detection sensor provided in a vehicle and detects a shift mode, or is electrically connected to an ECU connected to a shift stage detection sensor to shift the transmission. Information about the mode can be acquired. The control unit 40 is mounted on the circuit board 31 as shown in FIG. 1 together with the light generator 30 and is embedded in the knob body 10 .

The control unit 40 may control the vibration speaker 20 to emit various vibrations, sounds, and/or voices according to the shift mode as described above. Also, the control unit 40 may control the light generator 30 to emit various illumination lights according to the shift mode as described above. Therefore, the control unit 40 can accurately recognize the current shift mode, that is, the current vehicle driving state, to the driver through various vibrations, sounds and/or voices, and various illumination lights.

Meanwhile, the knob body 10 may include, for example, a housing 11 and a cover 12 as shown in FIG. 1 . As shown in FIGS. 1 and 3, the knob body 10 has an internal space accommodating the circuit board 31 on which the vibration speaker 20 and the light generator 30 are mounted.

The anti-vibration member 16 is interposed between the housing 11 and the cover 12 when the housing 11 and the cover 12 are coupled to each other. To this end, as shown in FIG. 4 , the housing 11 is provided with a step 11a on which the anti-vibration member 16 is seated along the rim of one side (top) of the open side. Accordingly, since the anti-vibration member 16 is seated on the step 11a, it is easily installed between the housing 11 and the cover 12.

The anti-vibration member 16 prevents vibration of the vibration speaker 20 attached to the cover 12 from being transmitted to the housing 11 . That is, in the knob body 10 , vibration of the vibration speaker 20 is not unnecessarily transmitted to the housing 11 by the anti-vibration member 16 . Accordingly, the knob body 10 concentrates the vibration of the vibration speaker 20 on the cover 12 so that information can be transmitted to the user reliably.

The cover 12 needs to be provided with support ribs 123 as shown in FIG. 5 . As shown, the support rib 123 is installed along the outer circumferential surface of the vibration speaker 20 to provide an accommodation groove 121 in which the vibration speaker 20 is accommodated. These support ribs 123 support the outer circumferential surface of the vibration speaker 20 to prevent the vibration speaker 20 from moving in a lateral direction. That is, the support rib 123 prevents excessive movement of the vibration speaker 20 . Accordingly, the support ribs 123 prevent the vibration speaker 20 from being separated from the cover 12 by preventing the vibration speaker 20 from moving in the lateral direction when the vibration speaker 20 vibrates.

As shown in FIG. 5, the cover 12 also needs to be provided with a protruding spacer 125 spaced apart from the bottom surface of the vibration speaker 20 by a predetermined gap to provide a ventilation passage for discharging sound and heat. there is. As shown, the spacer 125 is formed on the bottom surface of the cover 12 along the edge of the vibration speaker 20, and the contact surface of the vibration speaker 20 closely adhered to the bottom surface of the cover 12 is formed on the cover 12. It is spaced apart from the bottom of the to provide a ventilation passage. Accordingly, the spacer 125 discharges sound or heat from the vibration speaker 20 through the air passage.

On the other hand, when the housing 11 is made of an opaque material, the knob body 10 is installed in the housing 11 as shown in FIG. 1 and transmits the illumination light of the light generator 30 described above. ) may be provided. As shown in FIG. 2 , the transmission window 13 is installed on at least one of both sides of the housing 11 around the cover 12 . Accordingly, the transmission window 13 transmits and emits the illumination light of the light generator 30 toward either the driver's seat or the front passenger's seat. As shown in FIG. 1 , a plurality of transmission windows 13 are provided on both sides of the housing 11 so as to transmit illumination light to both sides of the housing 11 .

The transmission window 13 is for emitting the light generated by the light generator 30 to the outside and is made of a transparent material.

The transmission window 13 may be composed of, for example, a shield 13a and a ring frame 13b as shown in FIG. 1 . The shield 13a is made of transparent or translucent acrylic, glass, or plastic to shield the side of the housing 11 in a light-transmitting manner. The shield 13a may be formed of a lens such as a convex lens or a concave lens to diffuse the transmitted illumination light.

As shown, the ring frame 13b is formed in an annular shape, and a shield 13a is installed to shield the hollow to be permeable. As shown, the ring frame 13b is inserted into the side of the housing 11 and installed in a penetrating state. The ring frame 13b may be prefabricatedly fixed to the housing 11 by installing a member such as the hook 122 described above, or may be fixed by bonding or bolting.

As shown enlarged in FIG. 1 , the ring frame 13b is installed at one end of the shield 13a facing the inside of the housing 11 . That is, in the ring frame 13b, the shield 13a is installed in an eccentric state. Accordingly, as shown enlarged, the ring frame 13b provides an annular locking groove 13c on the outside of the shield 13a where the driver's finger F is inserted and caught at the other end of the ring frame 13b. Therefore, when operating the knob body 10, the driver's thumb is inserted into the locking groove 13c, so that the driver can easily operate the knob body 10, and the driver's hand does not easily slip on the knob body 10. .

As shown in FIG. 1, the ring frame 13b is installed with the above-described circuit board 31 parallel to the shield 13a. As illustrated, when a groove is formed on one side of the circuit board 31, the ring frame 13b may be provided with a hook (not shown) caught in the groove. Accordingly, the ring frame 13b can fix the circuit board 31 to the shield 13a in close contact with the hook through the hook.

On the other hand, the aforementioned fixing member 14 is a member coupled to the lower end of the housing 11 as shown in FIG. As shown in FIG. 3 , the fixing member 14 has a fastening hole 141 into which a fastening member such as a stop screw is fastened to fix the rod inserted into the insertion hole 111 of the housing 11 . Accordingly, the fixing member 14 may fix the shaft of the shift lever inserted into the insertion hole 111 of the housing 11 as a fastening member.

As shown in FIG. 3 , the fastening hole 141 of the fixing member 14 may be shielded by the cover member 15 . As shown, the cover member 15 is composed of a stopper-shaped member fitted into the fastening hole 141 .

On the other hand, as shown in FIG. 5 , the vibration speaker 20 is inserted into the receiving groove 121 formed in the cover 12 and fixed to the cover 12 by bolting or bonding. The vibration speaker 20 includes, for example, a case 21, a magnet 22, a voice coil 23, a terminal 28, a yoke 24, a disc spring 26, and It can be configured to include a cap 25.

The case 21 is installed on the cover 12 as shown in FIGS. 3 and 5 . As shown in FIG. 7, the case 21 has an accommodation space therein, and has one side that is formed in a container shape and opened. As shown in FIG. 6 , the case 21 has at least one ventilation hole 21a to dissipate heat generated therein and to prevent a vacuum.

The magnet 22 is composed of a permanent magnet and, as shown in FIG. 6, is installed in the receiving space of the case 21 (eg, bonded by bonding) to provide magnetic force. As shown in FIG. 6 , the voice coil 23 is spaced apart from the outer circumferential surface of the magnet 22 at a predetermined interval and generates electromagnetic force interacting with the magnet 22 . The voice coil 23 is composed of a conventional electromagnet made of a bobbin wound with a coil, and is fixed to the cap 25 as shown in FIG. 6 .

The terminal 28 is connected to the voice coil 23 to apply power for driving the voice coil 23 . The terminal 28 may be composed of, for example, an arc-shaped positive terminal 28a and an arc-shaped negative terminal 28b, as shown in FIG. ), and is made of a thin conductive metal plate to apply a positive current to the voice coil 23. As shown, the negative terminal 28b is formed identically to the positive terminal 28a, is installed on the cap 25 in a symmetrical state with the positive terminal 28a, and applies a negative current to the voice coil 23. As described above, since the terminal 28 is made of a thin conductive metal material and attached to the cap 25, a short circuit is prevented when the vibration speaker 20 vibrates, and installation is easy.

The yoke 24 forms a magnetic circuit together with the magnet 22 inside the case 21 . As shown in Figs. 6 and 7, the yoke 24 is formed in a container shape and one side is open. Thus, the magnet 22 is inserted into the yoke 24 through one side. The yoke 24 generates vibration while flowing inside the case 21 by the magnetic force of the magnetic circuit. Such a yoke 24 can be moved as it is elastically supported by a disc spring 26 to be described later.

As shown in FIG. 6 , the disc spring 26 elastically supports the yoke 24 as the yoke 24 is seated thereon. As shown in FIG. 7, the disc spring 26 is a thin metal plate in which a long hole is formed. As shown in FIG. 6, the disc spring 26 is fixed to the step formed inside the case 21 by bonding or bolting. However, the fixing method of the disc spring 26 is not limited to the above example, and any method is sufficient as long as it can be fixed to the case 21.

The cap 25 is made of a plate material as shown in FIG. 7 . As shown in FIG. 6 , the cap 25 is fixed to one open side of the case 21 by bonding or bolting to seal one side of the case 21 . The cap 25 is fixed to the set position of the case 21 by the centering means.

For example, as shown in FIG. 7, the centering means is formed in the form of a protrusion 25a protruding from the outer circumferential surface of the cap 25 and the edge of the end side of the case 21, so that the protrusion 25a is fitted. It can be configured to include a notch 21b that is caught. The installation direction of the cap 25 is always the same because the protrusion 25a is caught in the notch 21b, that is, the cap 25 is always installed only in the direction in which the protrusion 25a is caught in the notch 21b. . Therefore, since the cap 25 is always installed in the correct position during installation, the direction of the positive terminal 28a and the negative terminal 28b attached as described above does not change and does not rotate during vibration.

Meanwhile, the vibration speaker 20 further includes an extender that expands the refracting area of the disc spring 26 refracted by the yoke 24 by reducing the contact area of the yoke 24 with the disc spring 26. That is, the vibration speaker 20 can smoothly bend the disc spring 26 by the extender.

The extender is, for example, as shown in FIG. 6, a seating rod 24a protruding from the bottom of the yoke 24 toward the disk spring 26 and fixing the seating rod 24a to the center of the disk spring 26. Can be configured with fasteners. As shown enlarged in FIG. 6 , the seating bar 24a is seated at the center of the disc spring 26 and concentrates the weight of the yoke 24 on the center of the disc spring 26 when the yoke 24 vibrates. Therefore, since the yoke 24 contacts the disc spring 26 through the seating bar 24a, the contact area with respect to the disc spring 26 is reduced.

Here, the aforementioned fastener is, for example, a protruding nipple 24b protruding from the end of the seating rod 24a and a nipple holder formed in the form of a hole in the center of the disc spring 26, as shown enlarged in FIG. 6 ( 26a) can be included. In the nipple holder 26a, as shown enlarged, the nipple 24b is inserted to constrain the seating rod 24a to the center of the disc spring 26 through the nipple 24b.

On the other hand, in the case 21 described above, as shown in FIG. 6, it is preferable that the aforementioned ventilation hole 21a is formed through the mounting bar 24a. This is because the weight of the yoke 24 is concentrated in the area where the disk spring 26 is adjacent to the seating bar 24a, so that the most heat is generated in the central portion where the seating bar 24a is located. Thus, the case 21 smoothly dissipates heat through the ventilation holes 21a.

On the other hand, the vibration speaker 20 may further include a plate-shaped plate 27 as shown in FIG. 7 . The plate 27 is made of a magnetic material and forms a magnetic circuit together with the yoke 24 and also increases the weight of the yoke 24 . Thus, the yoke 24 can flow more smoothly when vibrating.

On the other hand, as shown in FIG. 1 , the knob for the shift lever of the vehicle according to an embodiment of the present invention may further include a photosensitive sensor 60 for detecting the intensity of light around the knob for the shift lever of the vehicle. The photosensitive sensor 60 may be provided on the circuit board 31 of the light generator 30 as shown. The control unit 40 controls the operation of the light generator 30 based on the intensity of light around the shift lever knob of the vehicle detected by the photosensitive sensor 60, that is, based on the detection signal of the photosensitive sensor 60. Thus, the intensity of light emitted from the light generator 30 may be adjusted. The control unit 40 may, for example, control the light generator 30 so that the intensity of light emitted from the light generator 30 is stronger during the daytime than during the nighttime.

As an additional embodiment, as shown in FIG. 8 , the control unit 40 includes a rear monitoring sensor (not shown) generally provided in a vehicle and detecting a distance between an obstacle behind the vehicle and the vehicle when the vehicle is reversing. It is directly electrically connected or electrically connected to the ECU connected to the rear monitoring sensor, and information about the distance between the obstacle and the vehicle may be obtained when the vehicle is reversing.

The control unit 40 may control the vibration speaker 20 to generate different vibrations or sounds according to a change in the distance between the obstacle and the vehicle when the vehicle moves backward. For example, the control unit 40 may generate the following vibrations from the vibration speaker 20 when the distance between the obstacle and the vehicle is 50 cm, 1 m, and 1.5 m, respectively, when the vehicle moves backward.

- When the distance between the obstacle and the vehicle is 50cm: 200Hz continuous vibration (causes strong warning)

- When the distance between the obstacle and the vehicle is 1m: 0 to 200Hz / 1 second cycle vibration, 0.5 second stop cycle repetition (weak warning)

- When the distance between the obstacle and the vehicle is 1.5m: 0 to 200Hz / 1.5 second periodic vibration, 1 second stop cycle repeated (causing caution)

Also, for example, when the distance between the obstacle and the vehicle is 50 cm, 1 m, and 1.5 m, respectively, when the vehicle is reversing, the vibration speaker 20 may generate the following sound.

- When the distance between the obstacle and the vehicle is 50cm: 'The obstacle is 50cm from the rear'.

- When the distance between the obstacle and the vehicle is 1m: 'An obstacle is 1m behind'

- When the distance between the obstacle and the vehicle is 1.5m: 'An obstacle is 1.5m behind' sounds.

Also, the control unit 40 may control the light generator 30 to generate different lights according to a change in the distance between the obstacle and the vehicle when the vehicle moves backward.

In this way, since different vibrations and/or sounds or different lights may be generated according to a change in the distance between the obstacle and the vehicle when the vehicle is reversing, the driver can sense the difference between the obstacle and the vehicle through these vibrations, sounds and/or lights. Distance changes can be accurately recognized.

In conclusion, the control unit 40 controls the vibration speaker 20 or the light generator 30 to generate vibration, sound, or light set according to the distance between the rear obstacle and the vehicle when the vehicle moves backward. Accordingly, the control unit 40 provides various sounds, voices, vibrations, or illumination light according to the set value for each shift mode when the vehicle moves backward.

In the knob for the shift lever of the vehicle according to the embodiment of the present invention configured as described above, the control unit 40 operates the vibration speaker 20 according to the shift mode of the vehicle to generate various vibrations for each shift mode. At this time, the vibration speaker 20 transmits vibration through the cover 12 of the knob body 10 as shown in FIG. 2 . However, in the vibration speaker 20, vibration is not transmitted to the housing 11 of the knob body 10 by the anti-vibration member 16.

The control unit 40 may output a warning sound from the vibration speaker 20 through frequency adjustment. The control unit 40 may output a warning sound along with vibration. Also, the control unit 40 operates the light generator 30 according to the shift mode to emit various illumination lights for each shift mode. At this time, the light generator 30 emits illumination light through the transmission window 13 installed on the side of the housing 11 as shown in FIG. 2 . Accordingly, the driver can accurately recognize the current shift mode through vibration, sound, voice and/or lighting.

As described above, the control unit 40 operates the vibration speaker 20 and the light generator 30 even when the vehicle is reversing to provide various sounds, voices, vibrations, or lighting according to the obstacles on the rear side of the vehicle and the distance of the vehicle. do. Accordingly, the driver can confirm this and back more safely.

The control unit 40 controls the dimming of the light generator 30 according to the ambient illumination of the knob body 10 when the photosensitive sensor 60 is provided. Therefore, the driver can clearly recognize the illumination light of the light generator 30 even at night or during the day or in cloudy weather.

Meanwhile, as shown in FIG. 6 , the vibration speaker 20 provides vibration, sound, or voice as the yoke 24 supported by the disk spring 26 flows together with the magnet 22 . At this time, the vibration speaker 20 dissipates heat and sound generated by the flow of the yoke 24 through the ventilation hole 21a formed in the case 21 . Also, since vacuum is prevented in the vibration speaker 20 through the ventilation hole 21a, the yoke 24 vibrates smoothly.

In the vibration speaker 20, as shown in FIG. 7, since the terminal 28 is made of an arc-shaped thin plate and attached to the cap 25, not only the terminal 28 is not short-circuited during vibration, but also the terminal 28 during assembly. ) is not truncated. In the vibration speaker 20, since the yoke 24 is seated on the disk spring 26 through the mounting bar 24a of the extender, the disk spring 26 is smoothly refracted during vibration.

The vibration speaker 20 is supported by the support ribs 123 as shown in FIG. 5 during vibration, so that transverse flow is prevented. Therefore, the vibration speaker 20 is not separated from the cover 12 of the knob body 10 even when vibrating repeatedly.

As shown in FIG. 5 , the vibration speaker 20 emits sound or heat through an air passage provided by the spacer 125 . Accordingly, the vibration speaker 20 can smoothly transmit sound and is easily cooled.
