Abstract
Description
Technical Field
[0001] The present invention relates to a position detection device for a cable and an electronic manual transmission having a position detection device for a shift cable that detects a moving position of the cable. More specifically, the present invention relates to a position detection device for a cable and an electronic manual transmission having a position detection device for a shift cable, wherein, in a shift lever of a vehicle having a manual transmission provided with an electronic clutch, the recognition speed of the operation of the shift lever is improved, and the reliability is enhanced due to the accurate sensing performed. Background Art
[0002] Generally, during the driving of the vehicle, the transmission installed on the vehicle performs the function of appropriately changing the driving force generated from the engine according to the driving conditions of the vehicle, thereby transmitting the driving force to the driving wheels. Meanwhile, the transmission is divided into a manual transmission, an automatic transmission, and a continuously variable transmission according to the operation method.
[0003] This manual transmission is a method in which a select cable and a shift cable are respectively subjected to tension in response to the operation of a shift lever installed inside a vehicle, and a select lever and a shift lever provided on a transmission side are enabled to operate independently, thereby completing power transmission according to the shifting of a corresponding gear train among a plurality of gear trains provided inside the transmission.
[0004] In recent years, a method for electronically controlling a clutch pedal that performs control of a clutch that must be configured for a manual transmission has been proposed. That is, when a manual transmission is to be shifted, the clutch pedal should be stepped on to control the operation of the clutch. However, there is a problem that when driving on a road section that requires frequent shifting, as the number of repetitions of stepping on the clutch pedal increases, the driver feels fatigued. In order to solve this problem, an automatic transmission is applied to a vehicle, but there is a problem that the characteristics and effects of a manual transmission are inevitably excluded.
[0005] Therefore, a structure for performing clutch control is applied to a shift lever having a mode of a manual transmission.
[0006] However, in order to control the clutch of the manual transmission through the shift lever, a sensor should be installed on the shift lever. However, since the shift lever and the sensor are configured to rotate together, there is a problem that when the shift lever is operated, an impact sound is generated due to the impact between the shift lever and the sensor.
[0007] In addition, the shift lever of the manual transmission performs the shift operation quickly, so when the sensor cannot accurately and quickly detect the movement of the shift lever, the shift operation is not performed at an appropriate time. In addition, because the additional configuration for connecting the shift lever and the sensor to each other becomes complicated, the center console layout for providing such a configuration is disadvantageous.

BRIEF DESCRIPTION OF THE DRAWINGS
[0027] The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description presented in conjunction with the accompanying drawings, in which:
[0028] Figure 1 is a view showing a position detection device for a cable according to an embodiment of the present invention; and
[0029] Figures 2 to 9 It is shown Figure 1 A view of a position detection device for a cable is shown. DETAILED DESCRIPTION
[0030] Hereinafter, a position detecting device for a cable and an electronic manual transmission having the position detecting device for a shift cable according to preferred embodiments of the present invention will be described with reference to the accompanying drawings.
[0031] Figure 1 is a view showing a position detection device for a cable according to an embodiment of the present invention, and Figures 2 to 9 It is shown Figure 1 A view of a position detection device for a cable is shown.
[0032] like Figures 1 to 3 As shown, the position detection device for a cable according to the present invention includes a socket 20, a movable body and a sensor module 40; the socket 20 is provided with a guide shell 21, the guide shell 21 is configured to allow the cable 10 to pass therethrough, extending in a straight line, and a through hole 22 is configured therein, thereby the cable 10 passes therethrough; the movable body is connected to the cable so as to move with the cable, is located in the through hole of the guide shell, and is provided with a transmitter for transmitting the moving position of the cable 10; the sensor module 40 is installed in the guide shell 21 and fixed to the guide shell 21, and senses the position of the transmitter 31 that moves with the cable 10.
[0033] That is, the present invention is characterized in that a socket 20 is provided, the socket 20 is provided with a guide housing 21 for guiding the linear movement of the cable 10, and the sensor module 40 provided in the guide housing 21 senses the movement of the movable body 30 provided on the cable 10, thereby detecting the movement of the cable 10.
[0034] Here, the socket 20 may be fixed to a structure and configured so that the cable 10 can pass therethrough. In such a socket 20, a guide housing 21 having a through hole 22 configured therein is configured to extend straight, whereby the cable 10 passes through the through hole 22. As a result, the cable 10 is restricted from vertical movement inside the guide housing 21 and operates only straight, thereby enabling accurate sensing based on its behavior.
[0035] On the other hand, the cable 10 is coupled with the movable body 30, and the movable body 30 is provided with a transmitter 31 for transmitting a position. Here, the transmitter 31 may be constituted by a magnet, and the movable body 30 is provided to mount the magnet on the cable 10. After the steel insertion guide 30c is coupled to the cable 10 by a swaging process, the movable body 30 may be provided by inserting and injecting the plastic movable body 30 on the insertion guide 30c, whereby the transmitter 31 may be coupled with the cable 10 through the movable body 30. In this case, the transmitter 31 may be integrally configured by being inserted and injected into the movable body 30, or may be separately configured and mounted on the movable body 30. In addition, the movable body 30 is provided with a mounting groove 30a, and the transmitter 31 is inserted into and fixed to the mounting groove 30a, so that when the transmitter 31 is inserted into the mounting groove 30a, the transmitter 31 does not protrude to the outside of the movable body 30. In this way, since the transmitter 31 is built into the mounting groove 30a in the movable body 30, when the movable body 30 moves, the transmitter 31 does not interfere with the through hole 22 of the guide housing 21 to prevent damage thereof, thereby maintaining the sensing performance.
[0036] Meanwhile, the sensor module 40 is installed in the guide housing 21 and senses the position of the transmitter 31 moving together with the cable 10. Such a sensor module 40 may be constituted by a PCB sensor and extends along the longitudinal direction of the guide housing 21 so as to accommodate the moving range of the movable body 30 moving together with the cable 10.
[0037] As a result, when the cable 10 is moved by a specific operation, the movable body 30 moves linearly as the cable 10 moves linearly in the guide housing 21 of the socket 20. At this time, the sensor module 40 senses the position movement of the transmitter 31 provided on the movable body 30, whereby the moving distance of the cable 10 can be accurately determined, thereby being able to execute a command according to the specific operation of precise control.
[0038] The present invention will be described in more detail below. Figure 4 As shown, the movable body 30 slides in the through hole 22 of the guide shell 21, and the through hole 22 is configured so that a portion of the inner peripheral surface forms an angle, and the movable body 30 of the cable 10 can also be configured so that a portion of its outer peripheral surface forms an angle, so that its construction is the same as the construction of the inner peripheral surface of the through hole 22.
[0039] That is, the movable body 30 slides linearly in the through hole 22 of the guide housing 21. At this time, when the movable body 30 rotates in the through hole 22, the accuracy of sensing may be deteriorated. Therefore, the through hole 22 is configured so that a part of the inner peripheral surface forms an angle, and the movable body 30 is also configured so that a part of the outer peripheral surface forms an angle, so that its configuration is the same as the configuration of the inner peripheral surface of the through hole 22, so that the movable body 30 can perform only linear movement without rotating in the through hole 22. The configuration of the inner peripheral surface of the through hole 22 and the configuration of the outer peripheral surface of the movable body 30 may each have only one portion forming an angle, and can be applied in various forms.
[0040] Meanwhile, the sensor module 40 is mounted on the corner-forming portion of the guide housing 21, and the transmitter 31 is mounted on the corner-forming portion of the movable body 30, whereby the sensor module 40 and the transmitter 31 are arranged accordingly. In other words, in the through hole 22 of the guide housing 21, the movable body 30 is restricted when it rotates and can only move in a straight line. Meanwhile, the sensor module 40 is mounted on the corner-forming portion of the guide housing 21, and the transmitter 31 is mounted on the corner-forming portion of the movable body 30, whereby the sensor module 40 and the transmitter 31 are arranged at positions facing each other accordingly. Therefore, the sensor module 40 can accurately determine the position of the transmitter 31 according to the movement of the movable body 30. Of course, although the sensor module 40 and the transmitter 31 can be applied to various positions corresponding to each other, it is preferred that the positions of the sensor module 40 and the transmitter 31 are each located on the corner-forming portion to ensure the convenience of installation and maintain the sensing performance.
[0041] At the same time, if Figure 1 As shown, the socket 20 can be provided with a guide tube 23 extending straightly from the opposite side of the guide shell 21, the end of the cable 10 on the guide tube 23 side can be connected to the guide rod 11 inserted into the guide tube 23, so as to move linearly, and the end of the cable 10 on the guide shell 21 side can be provided with a protective cable 12, the protective cable 12 has a hollow portion, and is inserted into the guide shell 21 and connected to the guide shell 21.
[0042] In this way, the socket 20 is provided with a guide housing 21 and a guide rod 11, the guide housing 21 extends linearly to one side thereof, and the guide rod 11 extends linearly to the opposite side thereof, thereby guiding the linear movement of the cable 10. Here, the guide rod 11 is coupled to one end of the cable 10 on the guide tube 23 side, and moves linearly in a state of being inserted into the guide tube 23, and one end of the cable 10 on the guide housing 21 side is guided to move linearly in a state of being surrounded by the protective cable 12.
[0043] As a result, when the guide rod 11 is inserted into the guide tube 23, passes through the guide housing 21 of the socket 20, and passes through the protection cable 12, the length of the linear guide is ensured so that the cable 10 can accurately perform only linear movement.
[0044] On the other hand, Figure 6 to Figure 7 As shown, the guide shell 21 can be constructed with a plurality of anti-separation protrusions 22a on the inner circumferential surface of the end into which the protective cable 12 is inserted, the protective cable 12 can be provided with an anti-separation portion 13 inserted into the guide shell 21 and connected to the guide shell 21, and the anti-separation portion 13 can be constructed with a plurality of anti-separation grooves 13a into which the anti-separation protrusions 22a are inserted.
[0045] In other words, the anti-separation groove 13a is constructed in the anti-separation part 13, and the anti-separation protrusion 22a inserted into the anti-separation groove 13a is constructed in the guide shell 21, whereby, when the protective cable 12 is inserted into the guide shell 21, the anti-separation protrusion 22a is inserted into the anti-separation groove 13a, thereby ensuring a strong fastening force.
[0046] In other words, the anti-separation part 13 made of steel of the protection cable 12 is coupled with the protection cable 12 by swaging, and the guide housing 21 made of plastic is inserted and discharged onto the anti-separation part 13. Therefore, the anti-separation part 13 is manufactured so that a configuration is achieved in which the protection cable 12 is inserted into the guide housing 21. At this time, it is configured so that the anti-separation protrusion 22a of the guide housing 21 is inserted into the anti-separation groove 13a, thereby improving the fastening force and ensuring durability.
[0047] On the other hand, Figure 8 As shown, the guide housing 21 is constructed with an opening slit 22b, which is opened to allow the outside to communicate with the through hole 22, and the movable body 30 is constructed with a fixing hole 30b at the portion exposed to the outside through the opening slit 22b, whereby when the fixing pin P1 is inserted into the fixing hole 30b, the position of the movable body 30 can be fixed.
[0048] That is, the movable body 30 coupled to the cable 10 should be positioned within the sensing range of the sensor module 40 within the through hole 22 of the guide housing 21 so that the sensor module 40 can accurately sense the transmitter 31. However, in the process of connecting the movable body 30 to the cable 10, as the position of the cable 10 changes, the movable body 30 may move in the guide housing 21. As a result, the movable body 30 and the transmitter 31 may not be in place, so that a sensing error may occur after the installation is completed.
[0049] Therefore, the movable body 30 is configured with a fixing hole 30b, the fixing pin P1 is inserted into the fixing hole 30b, and the guide housing 21 is configured so that the opening slit 22b is opened so that the outside can communicate with the through hole 22. Therefore, the movement of the movable body 30 is restricted by inserting the fixing pin P1 into the fixing hole 30b through the slit 22b, so that the position of the movable body 30 can be fixed. Here, the fixing pin P1 is configured to be grasped by the user, thereby, the position of the movable body 30 can be fixed when the cable 10 is connected thereto. In addition, the fixing pin P1 can be configured to improve the convenience of operation, wherein the fixing pin P1 is configured to be connected to the guide housing. In addition, the opening slit 22b is configured to extend in the longitudinal direction in the guide housing 21, so that the position adjustment operation of the movable body 30 can be easily performed.
[0050] Meanwhile, the position detection device for cables according to the present invention further includes a sensor housing 50 configured to surround the guide housing 21. The sensor housing 50 covers the sensor module 40 and the guide housing 21, thereby preventing the sensor module 40 from being externally polluted and damaged.
[0051] Here, the sensor housing 50 may be fixed so that one end thereof is inserted into the socket 20 and coupled to the socket 20, and the opposite end thereof is fixed to the guide housing 21 by a fixture P2 coupled to the guide housing 21. In this way, the sensor housing 50 is restricted from moving in one direction due to the insertion of one end thereof into the socket 20, and is restricted from moving in the opposite direction due to the fixing of the opposite end thereof to the guide housing 21 by the fixture P2. Here, the fixture P2 may be constituted by a clip, and may be configured to be inserted into a clip groove 24 configured on the outer peripheral surface of the guide housing 21. Therefore, the guide housing 21 is surrounded by the sensor housing 50 and is not exposed to the outside, so that the sensor module 40 included is protected from contamination and impact.
[0052] At the same time, the present invention can be applied to a shift lever of a manual transmission equipped with an electronic clutch. Fig. 9As shown, the position detection device for the shift cable according to the present invention includes a cable 10, a socket 20, a movable body 30 and a sensor module 40; the cable 10 is connected to the shift lever L, so as to transmit the operating force of the shift lever L to the transmission; the socket 20 is fixed to the rod housing C, configured to allow the cable 10 to pass through, and configured to extend straightly, so as to guide the cable 10 to move straightly; the movable body 30 is coupled with the cable 10, so as to move together with it, is located in the socket 20, and is provided with a transmitter 31 that transmits the moving position of the cable 10; the sensor module 40 is installed in the socket 20 and senses the position of the transmitter 31 that moves together with the cable 10. Such a socket 20 is provided with a guide housing 21, which extends straightly and has a through hole 22 configured therein, so that the cable 10 can pass through the through hole 22, and the sensor module 40 can be installed in the guide housing 21.
[0053] That is, the socket 20 is fixed to the rod case C and is configured so that the cable 10 can pass through. In such a socket 20, the guide housing 21 configured with the through hole 22 is configured to extend straight, whereby the cable 10 passes through the through hole 22. As a result, the cable 10 is restricted from vertical movement inside the guide housing 21 and operates only straight, so that sensing can be accurately achieved according to its behavior.
[0054] On the other hand, when the cable 10 is connected to the shift lever L and moves linearly when the shift lever L is operated, the cable 10 is configured to be able to perform a shift operation of the transmission. Such a cable 10 is coupled to a movable body 30, and the movable body 30 is provided with a transmitter 31 that transmits a position. Here, the transmitter 31 may be composed of a magnet, and the movable body 30 is provided to mount the magnet on the cable 10.
[0055] Meanwhile, the sensor module 40 is installed in the guide housing 21 and senses the position of the transmitter 31 moving with the cable 10. The sensor module 40 may be formed of a PCB sensor and extends along the longitudinal direction of the guide housing 21 so as to accommodate the moving range of the movable body 30 moving with the cable 10.
[0056] As a result, when the cable 10 is moved by the operation of the shift lever L, the movable body 30 moves linearly as the cable 10 moves linearly in the guide housing 21 of the socket 20. At this time, the sensor module 40 senses the position movement of the transmitter 31 provided on the movable body 30, thereby being able to accurately control the operation timing of the clutch by quickly and accurately determining the intention of shifting according to the operation of the shift lever L.
[0057] At the same time, the movable body 30 slides in the through hole 22 in the guide shell 21, and the through hole 22 is constructed so that a part of the inner peripheral surface forms an angle, and the movable body 30 can also be constructed so that a part of its outer peripheral surface forms an angle, so that its construction is the same as the construction of the inner peripheral surface of the through hole 22.
[0058] That is, the movable body 30 slides linearly in the through hole 22 of the guide housing 21. At this time, when the movable body 30 rotates in the through hole 22, the accuracy of sensing may be deteriorated. Therefore, the through hole 22 is configured so that a part of the inner peripheral surface forms an angle, and the movable body 30 is also configured so that a part of the outer peripheral surface forms an angle, so that its configuration is the same as the configuration of the inner peripheral surface of the through hole 22, so that the movable body 30 can perform only linear movement without rotating in the through hole 22.
[0059] At the same time, the socket 20 can be provided with a guide tube 23 extending straightly from the opposite side of the guide shell 21, and the end of the cable 10 on the guide tube 23 side can be connected to the guide rod 11 inserted into the guide tube 23, so as to move linearly and be connected to the shift lever L, and the end of the cable 10 on the guide shell 21 side can be provided with a protective cable 12, the protective cable 12 has a hollow portion, and is inserted into the guide shell 21 and connected to the guide shell 21.
[0060] In this way, the socket 20 is provided with a guide housing 21 and a guide rod 11, the guide housing 21 extends linearly to one side thereof, and the guide rod 11 extends linearly to the opposite side thereof, thereby guiding the linear movement of the cable 10. Here, the guide rod 11 is coupled with one end of the cable 10 on the guide tube 23 side, and moves linearly in a state of being inserted into the guide tube 23, and one end of the cable 10 on the guide housing 21 side is guided to move linearly in a state of being surrounded by the protective cable 12. Such a guide rod 11 may be provided with an eyelet end 11a connected to the shift lever L.
[0061] As a result, when the guide rod 11 is inserted into the guide tube 23, passes through the guide housing 21 of the socket 20, and passes through the protection cable 12, the length of the linear guide is ensured so that the cable 10 can accurately perform only linear movement.
[0062] On the other hand, an electronic manual transmission having a position detection device for a shift cable according to the present invention includes a shift cable 10, a socket 20, and is provided with a sensor module 40; the shift cable 10 is moved by the operation of a shift lever L, the socket 20 is fixed to a lever housing C and guides the movement of the shift cable 10, and the sensor module 40 senses the position of the shift cable 10 when the shift lever L is operated.
[0063] That is, the electronic manual transmission changes the operating state of the clutch by predetermining the shift intention of the shift lever L when operating the shift lever L. When the shift cable 10 connected to the shift lever L moves, the sensor module 40 provided in the socket 20 senses the position movement of the shift cable 10, so that the electronic manual transmission can control the operating state of the clutch according to the movement of the shift lever L.
[0064] That is, during the shift operation of the shift lever L, the sensor module 40 provided in the socket 20 senses the position movement of the shift cable 10 and transmits the shift intention to the controller according to the position movement of the shift cable 10. Therefore, the engagement state of the clutch is switched according to the operation of the shift lever L.
[0065] Therefore, since the present invention is configured to have a structure for sensing the movement of the shift cable 10 , the noise problem caused by the contact of the shift lever and the sensor is solved, and the manufacturing cost is reduced due to the simplified structure.
[0066] This shift cable 10 is provided with a movable body 30 located inside a socket 20 and equipped with a transmitter 31 that transmits a moving position, and the socket 20 is provided with a guide housing 21 that extends straight and has a through hole 22 constructed therein, whereby the shift cable 10 passes through the through hole 22, and the guide housing 21 can be equipped with a sensor module 40.
[0067] Here, the transmitter 31 may be constituted by a magnet, and the movable body 30 is provided to mount the magnet on the shift cable 10. The sensor module 40 is installed in the guide housing 21 of the socket 20, and senses the position of the transmitter 31 moving together with the shift cable 10. Such a sensor module 40 may be constituted by a PCB sensor, and extend along the longitudinal direction of the guide housing 21, so as to be able to accommodate the moving range of the movable body 30 moving together with the cable 10.
[0068] As a result, when the shift cable 10 is moved by the operation of the shift lever L, the movable body 30 moves linearly as the cable 10 moves linearly in the guide housing 21 of the socket 20. At this time, the sensor module 40 senses the position movement of the transmitter 31 provided on the movable body 30, thereby being able to accurately control the operation timing of the clutch by quickly and accurately determining the intention of shifting according to the operation of the shift lever L.
[0069] At the same time, the movable body 30 slides in the through hole 22 in the guide shell 21, and the through hole 22 is constructed so that a part of the inner peripheral surface forms an angle, and the movable body 30 can also be constructed so that a part of its outer peripheral surface forms an angle, so that its construction is the same as the construction of the inner peripheral surface of the through hole 22.
[0070] That is, the movable body 30 slides linearly in the through hole 22 of the guide housing 21. At this time, when the movable body 30 rotates in the through hole 22, the accuracy of sensing may be deteriorated. Therefore, the through hole 22 is configured so that a part of the inner peripheral surface forms an angle, and the movable body 30 is also configured so that a part of the outer peripheral surface forms an angle, so that its configuration is the same as the configuration of the inner peripheral surface of the through hole 22, so that the movable body 30 can perform only linear movement without rotating in the through hole 22.
[0071] The position detection device for a cable constructed with the structure as described above is characterized in that, in the shift lever of a manual transmission vehicle equipped with an electronic clutch, the shift lever and the sensor are constructed not to contact each other, thereby eliminating the generation of impact sound caused by the contact between the shift lever and the sensor; and simplifying the structure of the shift lever and the sensor, thereby reducing manufacturing costs and improving productivity.
[0072] While the present invention has been particularly shown and described with reference to specific embodiments thereof, it will be apparent to those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
