Description

[Technical Field]

[0001] The present invention relates to a compactly constructed shift range switching device that is a switch mounted on a vehicle and that performs a vehicle shift range selection operation and / or lock / unlock or self-alignment return operation. [Background technology]

[0002] In recent years, there has been a trend in automobile switches to integrate switches with various functions in a complex manner. However, as the number of functions increases, the structure of the switches becomes more complex, and the possibility of malfunction due to the complex structure also increases.

[0003] In particular, not only convenient functions of a vehicle but also essential functions of a vehicle, such as a gear shift lever that changes the gear range, are being converted to mechanical-electronic or electronic switches. However, such switch devices have advantages and disadvantages depending on the type, such as durability, operability, and the ability to recognize operation due to the operability.

[0004] However, in terms of vehicle devices, the importance of durability and user recognition of the operating state through operation is emphasized, and switch structures according to the prior art have had problems such as excessive space occupied by components due to structural constraints or inconvenience in operation, etc. In particular, since the components of the switch operate independently, it has been very difficult to realize a compact switch device because each component is individually arranged.

[0005] In particular, recent vehicle shift switches are electronically configured using shift-by-wire systems, and due to the characteristics of electronic configurations, various safety features tend to be added. However, the addition of functions makes the device more complex, and the increased cost due to the overlapping components is accompanied by problems such as malfunctions and maintenance.

DETAILED DESCRIPTION OF THE INVENTION

[0046] An electronic shift range switching device according to a preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. First, when referring to components in each drawing, please note that the same components are referred to by the same reference numerals whenever possible, even if they appear in different drawings. Furthermore, when describing the present invention, if it is determined that a detailed description of related known configurations or functions may unnecessarily obscure the gist of the present invention, such a detailed description will be omitted.

[0047] The present invention is an electronic shift range changing device for adjusting the gear range of a vehicle, and as shown in Figures 1 and 2, the electronic shift range changing device 10 of the present invention includes a housing unit 100, a shift knob unit 200, and a locking correction integrated unit 300.

[0048] The housing unit 100 includes a housing cover 110 and a housing base 120. The housing cover 110 and the housing base 120 are fastened together to form an internal space in which other components can be disposed. The housing cover 110 has a housing cover through-hole 111 through which one end of a shift knob unit 200 (described below) is disposed inside and the other end is exposed to the outside, allowing operation by a user, particularly a driver. The housing cover 110 has a cover fastening portion 113 on a side thereof, and the housing base 120 has a base fastening portion 123 on a side thereof, and the cover fastening portion 113 and the base fastening portion 123 are engaged with each other to prevent the housing cover 110 and the housing base 120 from being undesirably separated from each other. Alternatively, the housing cover 110 and the housing base 120 may be fastened together by a separate fastening member such as a bolt.

[0049] The unit board 900 described below is disposed in the internal space formed by the housing cover 110 and the housing base 120 to transmit electrical signals from other components, and forms an electrical connection structure with an external device through a board connector (not shown).

[0050] The housing unit 100 of the present invention further includes a housing shaft 130, which can form a stable rotation support structure for the shift knob unit 200 of the present invention. In some cases, the housing shaft can be integrally formed with the housing base, but it can also be configured to be separately connected as in this embodiment.

[0051] At the upper end of the housing shaft 130, a part of the configuration of knob stopper portions 260, 270 that perform a stopping function of the shift knob unit described below may be disposed.

[0052] As shown in Figures 2 and 3, the shift knob unit 200 of the present invention has one end exposed to the outside of the housing unit 100 and the other end disposed inside the housing unit 100 and is rotatable relative to the housing unit 100.

[0053] More specifically, the shift knob unit 200 in this embodiment includes a knob outer body 210, a knob inner body 220, a knob skirt body 230, and a knob cap 250, but the shift knob unit 200 is not limited to these and can be modified in various ways according to design specifications within the range in which it can be rotated by a driver or the like.

[0054] A knob outer body groove 211 is formed on the outer circumferential surface of the knob outer body 210, which can prevent slippage when the driver grips and turns the knob.

[0055] A knob cap 250 is placed on the upper end of the knob outer body 210 to provide an exterior finish, and the knob inner body 220 is engaged inside the knob outer body 210, restricting the relative rotation of the knob outer body 210 and the knob inner body 220, allowing them to rotate together as if they were formed integrally.

[0056] In this embodiment, a knob skirt body 230 is disposed between the knob outer body 210 and the knob inner body 220. The knob skirt body 230 has a wider outer diameter than the knob inner body 220, and when projected from the housing cover through hole 111 side, includes the housing cover through hole 111 therein and has a wider effective area, thereby preventing foreign matter from entering the inside of the housing unit 100.

[0057] The knob cap 250 is connected to the upper end side of the knob outer body 210 to complete the exterior, but in some cases, a switching detection element such as a separate touchpad may be placed in the position of the knob cap 250 to form a separate input section.

[0058] Since the electronic shift range switching device 10 of the present invention is realized by a selector switch for selecting a gear range, it may be configured so that the rotation direction of the shift knob unit 200 is permitted only within a preset angular range and is restricted outside of that range. That is, the shift knob unit 200 is rotatably disposed on the housing shaft 130 of the housing unit 100, and the shift knob unit 200 further includes knob stopper portions 260, 270. The knob stopper portions 260, 270 restrict the rotation of the shift knob unit 200.

[0059] More specifically, the knob stopper portions 260, 270 of the present invention include a knob stopper body 260 and a knob stopper corresponding portion 270. The knob stopper body 260 is disposed on the housing shaft 130 of the housing unit 100, and includes a knob stopper main body 261 and a knob stopper shaft body 263. Knob stopper main body 261 is formed with knob stopper main body grooves 267 of a preset angle range, and knob stopper main body contact surfaces 265 are provided on the side of knob stopper main body 261 to separate knob stopper main body grooves 267. Knob stopper shaft body fastening part 269 is formed on the side of housing shaft fastening part 131 formed on the housing shaft 130, and knob stopper shaft body fastening part 269 is fastened to knob stopper shaft body 263 to form a positionally fixed state.

[0060] The knob stopper corresponding portion 270 is disposed on the shift knob unit 200 side, and a knob stopper main body contact surface 265 is provided on the side of the knob stopper main body 261 so as to define the knob stopper main body groove portion 267. By engaging with the knob stopper body 260 within a predetermined angle range, the relative rotation between the shift knob unit 200 and the knob stopper body 260 is restricted. Ultimately, the knob stopper main body contact surface 265 is engaged with the knob stopper corresponding portion 270 as the shift knob unit 200 rotates, thereby restricting the rotation angle range of the shift knob unit 200.

[0061] 13, 15, 18, 20, and 22 show relative positional variations or relative position restriction states of knob stopper body 260 and knob stopper corresponding portion 270 in the positions of P shift range, R shift range, N shift range, D shift range, and S shift range, which are selected by rotation of shift knob unit 200. Counterclockwise rotation of shift knob unit 200 from the P shift range position in Fig. 13 is restricted, relative rotation is possible in the R shift range position in Fig. 15 and the N shift range position in Fig. 18, and clockwise rotation of shift knob unit 200 to the D shift range position in Fig. 20 is permitted. 22, clockwise rotation of shift knob unit 200 to the S gear range may be permitted, but in this case, shift knob unit 200 may be configured to rotate downward with a predetermined amount of pressure, and the contact rotation restriction state between knob stopper body 260, which is fixed at the upper end, and knob stopper corresponding portion 270 may be released, allowing selection of the S gear range by additional clockwise rotation. In this case, a resilient portion (not shown) may be provided at the lower end of shift knob unit 200, which may form a structure that restricts relative positional movement or relative contact between knob stopper body 260 and knob stopper corresponding portion 270 within the normal gear range after the shift knob unit 200 returns to its original position in the counterclockwise direction and after the pressure applied to the shift knob unit 200 is removed.

[0062] As shown in FIGS. 4 to 6, the locking collection integrated unit 300 of the present invention adjusts whether or not rotation of the shift knob unit 200 is interrupted and automatically returns the shift knob unit 200 to the P range under preset conditions. To prevent accidents due to sudden vehicle acceleration or erroneous operation, the present invention employs a rotation interruption mechanism that maintains a locked state even when the vehicle is in the P or N range after starting the vehicle, unless a braking-on signal is received from the vehicle brake sensor when the vehicle brake is applied, and unlocks the lock only when a braking-on signal is received from the vehicle brake sensor. Furthermore, when the vehicle is in an unsafe position, such as the D range, after the engine is turned off, the vehicle's gear range is automatically returned to a preset range, i.e., the P range in this embodiment, by auto-alignment, thereby preventing problems caused by the shift range when the vehicle is later re-entered and started. Here, the rotation interruption and auto-alignment return drive of the locking collection integrated unit in the present invention are performed by a single driver.

[0063] More specifically, the locking collection integrated unit 300 includes an integrated single driving unit 400 , an interlocking unit 500 , and a self-collection unit 600 .

[0064] The integrated single drive unit 400 includes a single drive 410, which is realized by an electric motor in this embodiment, and the type of the electric motor can be selected in various ways according to predetermined design specifications.

[0065] The interlocking unit 500 adjusts whether or not the rotation of the shift knob unit 200 is interrupted using the driving force transmitted from the single drive unit 400, and the self-correction unit 600 uses the driving force transmitted from the single drive unit 400 to automatically return the position of the shift knob unit 200 to the P range under preset conditions.

[0066] Fig. 7 shows a plan view of a portion of the configuration, and Fig. 8 shows a cross-sectional view of Fig. 7. Looking first at the drive side, i.e., integrated single drive unit 400, single drive device 410 of integrated single drive unit 400 is driven in response to a drive control signal from a control unit (not shown) to generate a drive force. This drive force can operate at different speeds and torques depending on the drive conditions, making it possible to limit the rotation of shift knob unit 200 and realize automatic alignment recovery of the gear range after the vehicle engine is turned off.

[0067] The integrated single driver unit 400 further includes a single driver holder 420 for holding the single driver 410, and in some cases, the single driver holder 420 may further include a connector for electrical connection.

[0068] The integrated single driving unit 400 further includes a single driving transmission part 430 and a single sharing transmission part 440. The single driving transmission part 430 contacts the single driving device 410, receives the driving force generated by the single driving device 410, and transmits it to the interlocking unit 500. In this embodiment, the single driving transmission part 430 and the single driving device 410 are directly connected, but this can be modified in various ways depending on the design specifications.

[0069] The single driver transmission part 430 includes a single driver first transmission part 431 and a single driver second transmission part 433. The single driver first transmission part 431 and the single driver second transmission part 433 are formed with a gear transmission structure, but this is just an example and may be variously modified, such as a belt pulley transmission structure, depending on the case.

[0070] The single driving first transmission part 431 is disposed on the drive shaft of the single driving unit 410, and the single driving second transmission part 433 rotates while meshing with the single driving first transmission part 431. The single driving first transmission part 431 is realized as a worm gear type having one end connected to the drive shaft of the single driving unit 410, and the single driving second transmission part 433 is formed as a worm wheel gear type meshing with the single driving first transmission part 431. The single driving second transmission part 433 has a structure formed integrally with a single shearing transmission drive gear 451 of the single shearing transmission gear part 450 described below.

[0071] More specifically, at least a portion of the single shear transmission part 440 contacts the single driver transmission part 430 to receive the driving force, and transmits the movable force for allowing the interlocking unit 500 to operate and the driving force to the interlocking unit 500 and the self-correction unit 600, respectively.

[0072] The single shearing transmission part 440 includes a single shearing transmission gear part 450. The single shearing transmission gear part 450 is in direct contact with the single driver transmission part 430 to receive the driving force, and transmits the moving force for allowing the interlocking unit 500 to operate and the driving force to the interlocking unit 500 and the self-correction unit 600, respectively.

[0073] The single shearing transmission gear unit 450 includes a single shearing transmission drive gear 451 and a single shearing transmission main gear 453. In this embodiment, the single shearing transmission drive gear 451 and the single shearing transmission main gear 453 are formed as a spur gear structure in which they are in contact with each other, but this can be modified in various ways according to design specifications.

[0074] The single shearing transmission drive gear 451 is integrally formed with the single driver transmission part 430 with a different gear ratio, and they are coaxially structured to share a rotation center, but the gear ratios of the different radii allow for adjustment of the rotation speed. In addition, the single shearing transmission main gear 453 meshes with the single shearing transmission drive gear 451, so that the rotation force of the single shearing transmission main gear 453 can be transmitted to the interlocking unit 500 and / or the self-collection unit 600.

[0075] Also, the single-sharing transmission part 440 may further include a single-sharing transmission detection gear part 460. The single-sharing transmission detection gear part 460 provides a component for detecting the rotation state of the single-sharing transmission gear part 450, and some components of the shift range detection unit 800 described below may be disposed therein.

[0076] More specifically, the single shearing transmission detection gear portion 460 includes a single shearing transmission detection main gear 461 and a single shearing transmission detection sub-gear 463. The single shearing transmission detection main gear 461 is integrally formed with the single shearing transmission main gear 453 with a different gear ratio, and the single shearing transmission detection sub-gear 463 rotates in mesh with the single shearing transmission detection main gear 461. This provides components for detecting the rotation state of the single shearing transmission gear portion 450, and by arranging some components of the shift range detection unit 800 described below, it is possible to check positional state information of some components of the interlocking unit and self-correction unit described below.

[0077] With this configuration of the integrated single drive unit, the drive force generated by the single drive unit 410, which is arranged singly, is generated and transmitted by the single drive transmission unit and the single sharing transmission unit as a drive force for locking / unlocking the interlocking unit 500 and the self-correction unit 600 and for realizing the auto-alignment return operation.

[0078] The interlocking unit 500 adjusts whether or not the rotation of the shift knob unit 200 is interrupted using the driving force transmitted from the single driving unit 400, and the interlocking unit 500 includes a trigger cam pin portion 520 and an interlocking cam pin portion 510.

[0079] At least a portion of the trigger cam pin portion 520 is movably disposed inside the housing unit 100 and is movable by the integrated single drive unit 400 .

[0080] More specifically, trigger cam pin portion 520 includes a trigger pin accommodating portion 525 , a trigger pin elastic portion 523 , a trigger pin 521 , and a trigger pin cam 527 .

[0081] The trigger pin receiving portion 525 is formed inside the housing unit 100, and more specifically, the trigger pin receiving portion 525 is formed inside the housing shaft 130. That is, the trigger pin receiving portion 525 is formed on the outer periphery of the lower end of the housing shaft 130 to form a space, and other components can be accommodated and disposed through one open side of the trigger pin receiving portion 525 so that the trigger pin elastic portion 523 and the trigger pin 521 can be movably accommodated therein.

[0082] The trigger pin elastic part 523 is disposed inside the trigger pin accommodating part 525, and one end is elastically supported inside the trigger pin accommodating part 525. The trigger pin elastic part 523 is realized as a coil type spring, but in some cases it may be realized as another pin type spring, and can be variously modified according to design specifications as long as it provides elastic force.

[0083] The trigger pin 521 has a structure in which one end is in contact with the trigger pin elastic portion 523 and is elastically supported, while the other end of the trigger pin 521 is in contact with the corresponding trigger pin cam 527 through the open space of the trigger pin receiving portion 525.

[0084] The trigger pin 521 includes a trigger pin body 5211 and a trigger pin interlocking contactor 5213. One end of the trigger pin body 5211 is in contact with the trigger pin elastic portion 523 and is elastically supported, and the other end is in constant contact with the trigger pin cam 527. The trigger pin interlocking contactor 5213 is integrally connected to the other side of the trigger pin body 5211 and is in contact with the interlocking cam pin portion 510 side. In this embodiment, the trigger pin interlocking contactor 5213 has a structure formed by extending upward from one side of the upper end of the trigger pin body 5211, so that the trigger pin 521 is realized in an inverted T shape in this embodiment, but the trigger pin 521 of the present invention is not limited to this.

[0085] The trigger pin cam 527 is positioned away from the trigger pin accommodating portion 525, and at least a portion of it is in constant contact with the other end of the trigger pin 521. In this embodiment, the trigger pin cam 527 is formed on at least one side of the integrated single driving unit 400, more specifically, on the inside bottom surface of the lower end of the single sharing transmission main gear 453 included in the single sharing transmission gear part 450 of the single sharing transmission part 440 of the single driving unit 400 (see Figures 9 and 10), but various positions can be selected depending on the design specifications. Trigger pin cam 527 includes trigger pin cam lock portion 527l and trigger pin cam unlock portion 527u. When trigger pin cam lock portion 527l and trigger pin 521 come into contact, trigger pin 521 forms a protruding state in the drawing and does not pressurize interlocking pin 511 (described later) toward the center, whereas when trigger pin cam unlock portion 527u and trigger pin 521 come into contact, trigger pin 521 forms a housed state in the drawing and pressurizes interlocking pin 511 (described later) toward the center, thereby forming an unlocked state in which interlocking pin 511 and interlocking pin cam 517 are unlocked from their locked states in the P range to N range (described later).

[0086] Meanwhile, at least a portion of the interlocking cam pin portion 510 is movably disposed inside the housing unit 100, and at least another portion thereof is driven by direct contact with the trigger cam pin portion 520 to interrupt the rotation of the shift knob unit 200.

[0087] The interlocking cam pin portion 510 includes an interlocking pin receiving portion 515, an interlocking pin elastic portion 513, an interlocking pin 511, and an interlocking pin cam 517. The interlocking pin receiving portion 515 is formed inside the housing unit 100, and more specifically, the interlocking pin receiving portion 515 is formed inside the housing shaft 130 of the housing unit 100. The interlocking pin receiving portion 515 has a groove space structure with one end open on the outer periphery of the housing shaft 130, and the interlocking pin elastic portion 513 and the interlocking pin 511 are movably received and disposed in the interlocking pin receiving portion 515. In this embodiment, the interlocking pin receiving portion 515 is formed integrally with and communicates with the trigger pin receiving portion 525; however, various modifications are possible, such as it may be formed as a separate space that is not connected to the trigger pin receiving portion 525 in some cases.

[0088] The interlocking pin elastic part 513 is disposed inside the interlocking pin receiving part 515, and one end is elastically supported inside the interlocking pin receiving part 515. The interlocking pin elastic part 513 is realized as a coil spring type, but various selections are possible as long as it provides elastic force to the interlocking pin 511 in a predetermined direction, i.e., through the open space of the interlocking pin receiving part 515.

[0089] One end of the interlocking pin 511 is in contact with the interlocking pin elastic portion 513 and is elastically supported, and the interlocking pin cam 517 is positioned away from the interlocking pin accommodating portion 515 and at least a portion of it is in constant contact with the other end of the interlocking pin 511.

[0090] The interlocking pin cam 517 (see FIG. 11, etc.) is configured to be formed inside the shift range detection main drive part 810 of the shift range detection unit 800, which will be described later. The interlocking pin 511 can be modified in various ways, such as being formed separately from the shift range detection main drive part 810 and being connected to it integrally without any relative rotation. The interlocking pin cam 517 has a cam profile depending on the distance from the center in the radial direction, and as shown in Figures 11, 12, 14, 16, 17, 19, and 21, the interlocking pin cam 517 includes an interlocking pin cam P range portion 517P, an interlocking pin cam R range portion 517R, an interlocking pin cam N range portion 517N, an interlocking pin cam D range portion 517D, and an interlocking pin cam S range portion 517S.

[0091] The interlocking pin cam P range section 517P refers to the cam profile section of the position taken when P range selection of the electronic shift range switching device 10 is achieved, the interlocking pin cam R range section 517R refers to the R range selection of the electronic shift range switching device 10, the interlocking pin cam N range section 517N refers to the N range selection of the electronic shift range switching device 10, the interlocking pin cam D range section 517D refers to the D range selection of the electronic shift range switching device 10, and the interlocking pin cam S range section 517S refers to the cam profile section of the position taken when S range selection of the electronic shift range switching device 10 is achieved. The interlocking pin cam P range portion 517P and the interlocking pin cam N range portion 517N are at a greater radial distance from the center of rotation and form an accommodation space for the end of the interlocking pin body 5111 described below, while the interlocking pin cam R range portion 517R, the interlocking pin cam D range portion 517D and the interlocking pin cam S range portion 517S are at a smaller radial distance from the center of rotation than the interlocking pin cam P range portion 517P and the interlocking pin cam N range portion 517N and form an area that contacts the end of the interlocking pin body 5111 described below.

[0092] In this case, the interlocking pin 511 includes an interlocking pin body 5111 and an interlocking pin trigger contactor 5113, one end of which is in contact with the interlocking pin elastic portion 513 and elastically supported, and the other end of which is in constant contact with the interlocking pin cam 517. The interlocking pin trigger contactor 5113 is integrally connected to the other side of the interlocking pin body 5111 and is in contact with the trigger cam pin portion 520. Like the trigger pin 521 described above, it forms an inverted T-shaped structure, but as described above, the specific shape can be modified according to design specifications.

[0093] In the interlocking unit 500 of this embodiment, interference may occur between the trigger cam pin portion 520 and the interlocking cam pin portion 510. That is, when at least a portion of the trigger cam pin portion 520 is driven toward the rotation center of the shift knob unit 200, it is possible for the trigger cam pin portion 520 to be driven together with the interlocking pin cam 517 and to be released from contact with the interlocking pin cam 517.

[0094] In other words, when at least a portion of the trigger cam pin portion 520 is driven toward the rotation center of the shift knob unit 200, at least a portion of the interlocking pin 511 of the interlocking cam pin portion 510 is driven together with the trigger pin 521, and the contact state between the interlocking pin 511 and the interlocking pin cam 517 can be released.

[0095] 4, at a contact point between the interlocking pin trigger contactor 5113 and at least a portion of the trigger cam pin portion 520, the interlocking pin trigger contactor 5113 is located closer to the rotation center of the shift knob unit 200 than at least a portion of the trigger cam pin portion 520. When the trigger pin 521 of the trigger cam pin portion 520 moves toward the rotation center of the shift knob unit 200, the trigger pin interlocking contactor 5213 of the trigger pin 521 abuts against the interlocking pin trigger contactor 5113, and when the trigger pin interlocking contactor 5213 moves toward the rotation center of the shift knob unit 200, the interlocking pin trigger contactor 5113 also moves together, and the end of the interlocking pin body 5111 abuts against the interlocking pin cam 517, thereby forming or changing the locked or unlocked state.

[0096] Meanwhile, the self-collection unit 600 according to one embodiment of the present invention uses the driving force transmitted from the single drive unit 400 to automatically return the position of the shift knob unit 200 to the P range under preset conditions, and includes a self-collection lead rib 610 and a self-collection following rib 620. The self-collection lead rib 610 is movable by receiving the driving force transmitted from the single drive unit 400, and the self-collection following rib 620 is disposed at a distance so as to be able to come into contact with the self-collection lead rib 610, and is rotatable about the rotation center of the shift knob unit 200 by receiving the driving force transmitted by the self-collection lead rib 610.

[0097] In this case, the self-collection leading rib 610 of the electronic shift range switching device 10 according to one embodiment of the present invention is integrally connected to at least one side of the single-sharing transmission part 440, more specifically, the single-sharing transmission main gear 453 side of the single-sharing transmission gear part 450, and the self-collection following rib 620 can be structured to be integrally formed on the shift range detection main driving part 810 side of the shift range detection unit 800.

[0098] That is, the electronic shift range switching device 10 according to one embodiment of the present invention further includes a shift range detection unit 800 that detects the rotational state of the shift knob unit 200 and the single-shared transmission part 440, and the self-collection leading rib 610 is integrally connected to at least one side of the single-shared transmission part 440, and the self-collection following rib 620 is integrally connected to at least one side of the shift range detection unit 800.

[0099] With this configuration, the driving force of the single driver 410 is transmitted via the single driving transmission unit 430, and the single sharing transmission gear unit 450 of the single driving sharing transmission unit 440 rotates the single sharing transmission main gear 453, changing the position of the self-collection leading rib 610 formed integrally with the single sharing transmission main gear 453. As a result, by pushing the self-collection following rib 620 to move it to a predetermined position, i.e., the P range position, an engagement structure is formed with the interlocking pin cam 517 formed on the shift range detection main driver 810, which can prevent starting restrictions caused by an incorrect shift range position that occurs when re-boarding the vehicle and switching the engine on after the engine is turned off.

[0100] Meanwhile, the locking collection integrated unit 300 of the electronic shift range switching device 10 according to one embodiment of the present invention may further include a detent unit 700, which tactilely detects the rotational movement of the shift knob unit 200 when the shift knob unit 200 rotates relative to at least a portion of the housing unit 100.

[0101] More specifically, the detent unit 700 includes a detent profile cam 740 , a detent receiving portion 730 , a detent pin 710 , and a detent elastic portion 720 .

[0102] The detent profile cams 740 are spaced apart from one another on the outer periphery of the housing shaft 130 of the housing unit 100. In this embodiment, the detent profile cam 740 has a structure in which a cam profile is formed on the inner surface of a separate ring-type body structure. Although not specifically shown in this embodiment, the shape and pattern of the detent profile cam 740 can be selected in a variety of ways. The detent receiving portion 730 is formed inside the housing shaft 130. In this embodiment, the detent receiving portion 730 has a structure in which it penetrates the housing shaft 130, but this can be modified in various ways depending on design specifications.

[0103] At least one end of the detent pin 710 is movably accommodated in the detent accommodating portion 730, and the other end is in direct contact with the detent profile cam 740 side, and at least a portion of the detent elastic portion 720 is arranged inside the detent accommodating portion 730, and at least one end is in contact with the detent pin 710 to elastically support the detent pin 710.

[0104] In this embodiment, the detent pins 710 are shown arranged at 180 degrees opposite each other, but they may be arranged in a single configuration, and the arrangement angle may be changed, and various other modifications may be made depending on the design specifications.

[0105] In this case, the self-collection unit 600 of the present invention may further have a configuration that restricts the operation of the detent pin 710. That is, the self-collection unit 600 of the present invention includes a self-collection detent retraction portion 630, which releases direct contact between at least a portion of the detent pin 710 and the detent profile cam 740 when the self-collection leading rib 610 and the self-collection following rib 620 are engaged and driven together.

[0106] More specifically, the self-collection detent retraction portion 630 includes a retraction housing portion 637 , a retraction pin 631 , a retraction elastic portion 633 , a retraction cam 635 , and a retraction detent pin contactor 639 .

[0107] The retraction accommodating portion 637 is formed as an open groove structure on the outer periphery of the housing shaft 130, and in this embodiment, the retraction accommodating portion 637 is formed in an area 180 degrees opposite the interlocking pin accommodating portion 515, but is not limited to this.

[0108] At least a portion of the retraction pin 631 is movably housed and disposed in the retraction housing portion 637, and the retraction elastic portion 633 has a structure in which one end contacts the retraction pin 631 and the other end is supported in contact with the inside of the retraction housing portion 637, thereby elastically supporting the retraction pin 631. In addition, the retraction cam 635 is always in contact with one end of the retraction pin 631 supported by the retraction elastic portion 633.

[0109] The retraction pin 631 includes a retraction pin body 6311 and a retraction pin detent contactor 6313, and the retraction pin body 6311 is elastically supported by the retraction elastic portion 633. In this embodiment, the retraction pin detent contactor 6313 is integrally formed by extending from one side of the retraction pin body 6311 and contacts the retraction detent pin contactor 639.

[0110] The retraction detent pin contactor 639 is formed integrally with the detent pin 710 and is capable of contacting the retraction pin 631, and is movable together when the retraction pin 631 is driven.

[0111] At this time, at at least a portion of the contact point between retraction detent pin contactor 639 and retraction pin 631, retraction detent pin contactor 639 is positioned closer to the rotation center of shift knob unit 200 than at least a portion of the retraction pin 631. That is, the outer surface of the retraction detent pin contactor 639 in the radial direction from the rotation center of the shift knob unit 200 is structured to come into contact with the inner surface of the retraction pin detent contactor 6313, and the state of contact with the retraction pin body 6311 is structured to change depending on the cam profile of the retraction cam 635. Therefore, when the retraction pin body 6311 is driven toward the center of the shift knob unit 200, the outer surface of the retraction detent pin contactor 639 that comes into contact with the inner surface of the retraction pin detent contactor 6313 changes. The driving force is transmitted to the detent pin 710 through the side, and the detent pin 710, which is connected to the retraction detent pin contactor 639, is driven backward toward the center of the shift knob unit 200, thereby releasing the contact state between the detent pin 710 and the detent profile cam 740. This also prevents the occurrence of detent contact noise and vibration between the detent pin 710 of the detent unit 700 and the detent profile cam 740 during the return operation by the self-collection unit 600 to form a self-aligned return state of the P shift range.

[0112] Furthermore, the electronic shift range switching device 10 of the present invention further includes a shift range detection unit 800, which detects at least the rotation state of the shift knob unit 200.

[0113] That is, shift range detection unit 800 includes a shift range detection main movable part 810, a shift range detection sub movable part 820, a shift range detection movable part 830, and a sub shift range detection fixed part 840. Shift range detection main movable part 810 is connected to shift knob unit 200 and is movable therewith, shift range detection sub movable part 820 is connected to shift range detection main movable part 810 so as to be relatively movable, shift range detection movable part 830 is disposed on shift range sub movable part 820, and shift range detection fixed part 840 is disposed on unit substrate 900 at a position corresponding to shift range detection movable part 830, and unit substrate 900 is disposed and fixed inside housing unit 100. In this embodiment, shift range detection movable part 830 is realized by a magnet, and shift range detection fixed part 840 is realized by a magnetic detection sensor.

[0114] Furthermore, in addition to the shift knob unit 200, the shift range detection unit 800 in this embodiment may further include components for detecting the driving operation state of the single sharing transmission main gear 453 as described above, and detecting position information of the relevant components in order to realize the locking / unlocking operation of the interlocking unit 500 to lock / unlock the rotation of the shift knob unit 200 by the locking collection integrated unit, and / or the operation of self-aligning a shift range other than a preset shift range to a preset shift range, for example, the P shift range, after the engine is turned off.

[0115] That is, the shift range detection unit 800 may further include a shift range sharing transmission detection movable part 860 and a shift range sharing transmission detection fixed part 850. The shift range sharing transmission detection movable part 860 is disposed on the single sharing transmission detection sub gear, and the shift range sharing transmission detection fixed part 850 is disposed on the unit substrate 900 at a position corresponding to the shift range sharing transmission detection movable part 860. The shift range sharing transmission detection movable part 860 is realized by a magnet, and the shift range sharing transmission detection fixed part 850 is realized by a magnetic detection sensor, which detect the rotation of the single sharing transmission main gear 453 side and can grasp the operating states and position information of the interlocking unit 500 and the self-correction unit 600.

[0116] The operation of the electronic shift range switching device 10 of the present invention will now be described with reference to the drawings. First, the electronic shift range switching device 10 is configured so that it cannot be operated immediately even when the driver switches the engine ON. For example, when the electronic shift range switching device 10 is set to a mode for establishing the P shift range, the driver depresses the brake pedal, generating a brake ON signal from the brake sensor. A vehicle control unit (not shown) applies a drive control signal to the single driver 410 to perform a lock / unlock operation. Upon receiving the drive control signal, the single driver 410 performs a predetermined rotational movement. This is transmitted via the single drive transmission unit 430, causing the single shearing transmission main gear 453 to rotate, which changes the state of contact between the trigger pin cam 527 and the trigger pin 521 of the interlocking unit 500 located on the lower bottom surface of the single shearing transmission main gear 453. That is, as described above, the trigger pin cam 527 is disposed apart from the trigger pin accommodating portion 525, and at least a portion thereof is in constant contact with the other end of the trigger pin 521. In this embodiment, however, the trigger pin cam 527 is structured to be formed on at least one side of the integrated single driving unit 400, more specifically, on the inside bottom surface of the lower end of the single sharing transmission main gear 453 included in the single sharing transmission gear portion 450 of the single sharing transmission portion 440 of the single driving unit 400. Trigger pin cam 527 includes trigger pin cam lock portion 527l and trigger pin cam unlock portion 527u. When trigger pin cam lock portion 527l and trigger pin 521 come into contact, trigger pin 521 forms a protruding state in the drawing and does not pressurize interlocking pin 511 (described later) toward the center. When trigger pin cam unlock portion 527u and trigger pin 521 come into contact, trigger pin 521 forms a housed state in the drawing and presses interlocking pin 511 (described later) toward the center, thereby forming an unlocked state that unlocks the locked state of interlocking pin 511 and interlocking pin cam 517 in the P range (described later) (see FIGS. 9 and 10). This also applies to forming an unlocked state that unlocks the locked state in the N range (see FIGS. 16 and 17). Using the driving force from integrated single drive unit 400, which includes a single single drive, of locking collection integrated unit 300, a predetermined rotational movement can be intermittently performed by switching between the locked and unlocked states through the operation of interlocking unit 500. By rotating shift knob unit 200, the unlocked state is maintained by contact between trigger pin 521 and trigger pin cam unlock portion 527u in the R speed range (see FIG. 14), D speed range (see FIG. 19), and S speed range (see FIG. 21), and this establishes the unlocked state of interlocking cam pin portion 510, allowing for stable rotation of shift knob unit 200.

[0117] Meanwhile, as shown in Figures 23 to 26, which are schematic perspective views showing the operating process of the self-correction unit of an electronic shift range switching device according to one embodiment of the present invention, and Figures 27 to 29, which are schematic partial plan views showing the operating process of the self-correction detent retraction part of the self-correction unit of an electronic shift range switching device according to one embodiment of the present invention, when the driver turns off the engine and an engine OFF signal is generated, and the position state of the shift knob unit 200 of the electronic shift range switching device 10 is in the D shift range rather than the P shift range or the N shift range due to an unintended operation by the driver, the vehicle control unit (not shown) can operate the self-correction unit 600 using the driving force from the integrated single drive unit 400 to perform the automatic alignment return operation for the shift range position. That is, when an engine-off signal is generated and a control unit (not shown) detects that the current gear range is the D gear range, the control unit applies a drive control signal to the single driver 410, the driving force of the single driver 410 is transmitted via the single drive transmission unit 430, the single sharing transmission main gear 453 rotates by the single sharing transmission gear unit 450 of the single drive sharing transmission unit 440, and the position of the self-collection leading rib 610 formed integrally with the single sharing transmission main gear 453 changes. As a result, the self-collection following rib 620 is pushed and moved to a predetermined position, i.e., the P range position, thereby forming an engagement structure with the interlocking cam 517 formed on the sharing range detection main driver 810, and this can prevent starting restriction due to an incorrect shift range position that occurs when re-boarding the vehicle after the engine is turned off and switching the engine on.

[0118] During this process, the self-correction detent retraction portion 630 can be operated to release the constant contact between the detent unit and the self-correction detent retraction portion 630 and prevent unnecessary noise generation, as described above.

[0119] The above description merely exemplifies the technical concept of the present invention, and various modifications and variations may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are for illustrative purposes only, and are not intended to limit the technical concept of the present invention. The scope of the present invention should be interpreted by the appended claims, and all technical concepts within the scope of the claims should be interpreted as being within the scope of the present invention.
