Description

Technical Field

[0001] This utility model relates to the field of automotive shifting technology, specifically to an electronic shift lever adjustment mechanism. Background Technology

[0002] Due to the ease of operation of automatic transmission vehicles, electronic and drive-by-wire gear shifters have become more common. Electronic gear shifters mainly include three types: rotary, lever, and paddle shifters. Rotary and paddle shifters rely entirely on sensors and drive-by-wire, while lever shifters often determine the gear position through electrical signals from contact switches.

[0003] In existing technologies, rotary and paddle-type electronic gear shifters are prone to accidental gear selection. Similarly, the positioning grooves of the electronic shift lever and gear lever in lever-type electronic gear shifters often cannot be locked, which is detrimental to the stable switching between automatic and manual gears and driving safety. Therefore, we propose an electronic shift lever adjustment mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide an electronic shift lever adjustment mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] An electronic gear shift lever adjustment mechanism includes a gear shift housing and a bottom housing detachably connected to the bottom of the gear shift housing. A gear shift paddle is hinged within the inner cavity of the gear shift housing. A gear shift lever passes through the center of the gear shift paddle. A pull rod is housed within the gear shift lever. Upper and lower slots are respectively formed at both ends of the pull rod. An upper positioning pin passes through the top of the upper slot, and a lower positioning pin passes through the bottom of the lower slot. A locking rod is telescopically engaged at one end of the gear shift lever that extends into the inner cavity of the bottom housing. A lower guide pin, engaging with the lower positioning pin, is formed at the end of the locking rod that extends into the lower slot. The bottom surface of the bottom shell has automatic point grooves arranged in parallel around the hinge center of the shift lever to cooperate with the locking lever. One end of the shift lever extending out of the shifter housing is detachably connected to a handle housing. The top of the handle housing is detachably connected to a handle cover. The cavity formed by the handle cover and the handle housing contains a locking handle. One end of the locking handle extends out of the handle cover, and the top edge of the other end of the locking handle has a V-shaped guide groove. The guide groove slides with the upper positioning pin. The handle cover contains a first spring, which is used to reset the locking handle.

[0007] Furthermore, a third spring is provided at the bottom of the inner cavity of the shift lever, which is sleeved on the outside of the locking lever. The two ends of the third spring respectively abut against the bottom end of the pull rod and the shoulder of the bottom of the locking lever.

[0008] Furthermore, a switch base is provided on one side of the inner cavity of the bottom shell, and a switch positioning groove corresponding to the automatic ignition groove is formed in the switch base. The switch positioning groove is used to install a contact switch, and a shift lever corresponding to the switch positioning groove is formed on the bottom surface of the shift lever near the switch base.

[0009] Furthermore, the shift paddle has a hinge cavity in the middle, the shift lever is hinged in the hinge cavity by a center pin, and the bottom of the pull rod has a center guide groove that slides with the center pin.

[0010] Furthermore, a manual sliding groove is provided on the bottom surface of the inner shell, located on one side of the automatic shifting groove. The manual sliding groove cooperates with the locking rod for manual gear shifting.

[0011] Furthermore, it also includes a top cover that is detachably connected to the top of the shifter housing. The top surface of the top cover has a conical limiting hole. A positioning cylinder is fitted on the top surface of the shifter housing. A ball bearing is fitted on the top of the shift lever. The ball bearing is in contact with the inner top surface of the top cover and the top spherical surface of the positioning cylinder.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a gear shift housing and a bottom housing for encapsulation. A gear shift lever is hinged within the gear shift housing by a gear shift block. The gear shift lever houses the pull rod and locking rod. A lower positioning pin slides into the lower guide groove, allowing the locking rod to be slidably installed in the lower slot at the bottom of the pull rod. A handle housing and a handle cover are provided at the top of the gear shift lever, encapsulating the locking lever. The top edge of the locking lever slides into the guide groove, where an upper positioning pin at the top of the pull rod falls into the guide groove. The pull rod and locking rod slide down within the gear shift lever, and the locking lever is engaged. The bottom end of the lever extends into the automatic shift slot, locking the shift lever position. Pressing the locking handle pushes the upper positioning pin through the guide slot, causing the pull rod to move upward. The pull rod then moves the locking lever upward, releasing the locking lever from the automatic shift slot. Moving the handle, which consists of the handle housing and handle cover, causes the shift lever to swing through the shift paddle. Through the allowance of the lower positioning pin and the lower guide slot, the locking lever exits through one automatic shift slot and enters another, realizing automatic gear shifting. The gear locking is more stable, the shifting operation is more convenient, and it helps improve driving safety.

[0014] 2. This utility model utilizes the elastic tension of the second spring to ensure stable rolling contact between the bushing, the top edge of the locking lever, and the guide groove. The third spring elastically pushes the locking rod downwards, stably pressing it into the automatic locking groove to maintain its stability. A hinge cavity is provided in the center of the shift lever, and a center pin hinges the shift lever and shift lever together. The center pin, in conjunction with the center guide groove, provides bidirectional limit on the lifting and lowering of the lever. Simultaneously, since the shift lever is hinged within the shifter housing, the shift lever is cross-hinged. When the driver presses the locking lever with their thumb, the lever is pulled upwards to release the locking rod. The handle, composed of the handle housing and handle cover, allows the shift lever to be turned towards the driver's side and switched to manual mode. A manual slide groove with an elliptical linear groove engages with the locking rod to lock the manual mode. The shift lever is moved to shift gears forward and backward, and the depth of the manual slide groove, under the reset action of the third spring, pushes the shift lever back to the center.

The inner bottom surface of the bottom shell 2 has automatic point grooves 3 arranged in parallel around the hinge center of the shift lever 8, which mate with the locking rod 26. Specifically, the inner bottom surface of the bottom shell 2 is a spherical concave surface. Multiple automatic point grooves 3 are provided, corresponding to the automatic gear positions, and arranged in an array around the hinge center of the shift lever 8. The bottom end of the automatic point grooves 3 is a conical groove. The locking rod 26 mates with the automatic point grooves 3. With the automatic gear locked, a handle housing 13 is detachably connected to one end of the shift lever 7 extending out of the shifter housing 1. A handle cover 14 is detachably connected to the top of the handle housing 13. Specifically, the handle housing 13 and the handle cover 14 form a handle. A through hole is formed inside the handle housing 13 to mate with the shift lever 7. A bolt connected to the shift lever 7 is screwed into the side wall at the bottom end of the handle housing 13. A locking handle 15 is placed in the cavity formed by the handle cover 14 and the handle housing 13. One end of the locking handle 15 extends out of the handle cover 14, and a V-shaped guide groove 18 is formed on the top edge of the other end of the locking handle 15. The guide groove 18 slides with the upper positioning pin 22. Specifically, a bushing 23 is fitted onto the upper positioning pin 22. The bushing 23 rolls with the upper positioning pin 22 and the guide groove 18. A first spring 17 is provided inside the handle cover 14. The first spring 17 is used to lock the pressure handle 15 to reset. Specifically, a stop 16 is provided near the extended end of the locking pressure handle 15.

One end of the first spring 17 abuts against the stop 16, and the other end of the first spring 17 abuts against the rib inside the handle cover 14. It can be sealed by the cooperation of the shift housing 1 and the bottom housing 2. The shift lever 7 is hinged in the shift housing 1 by the shift block 8. The shift lever 7 accommodates the pull rod 19 and the locking rod 26. The locking rod 26 is slidably installed in the lower slot 25 at the bottom end of the pull rod 19 by the sliding cooperation of the lower positioning pin 27 and the lower guide groove 28. The handle housing 13 and the handle cover 14 are provided at the top of the shift lever 7.The locking handle 15 is encapsulated by the cooperation of the handle housing 13 and the handle cover 14. The top edge of the locking handle 15 slides into the guide groove 18, where the upper positioning pin 22 at the top of the pull rod 19 is slidably engaged. The upper positioning pin 22 falls into the guide groove 18, and the pull rod 19 and the locking rod 26 slide down within the shift lever 7. The bottom end of the locking rod 26 extends into the automatic timing groove 3, locking the position of the shift lever 7. Pressing the locking handle 15 pushes the upper positioning pin 22 through the guide groove 18, thereby driving the pull rod 19. 9. Moving upwards, the locking lever 26 is moved upwards via the pull rod 19, releasing the locking lever 26 from the automatic shift groove 3. The handle, composed of the handle housing 13 and the handle cover 14, moves the shift lever 7 via the shift paddle 8. Through the allowance of the lower positioning pin 27 and the lower guide groove 28, the locking lever 26 exits through one automatic shift groove 3 and enters another, realizing automatic gear shifting. This results in more stable gear locking and more convenient gear shifting.

[0023] In this embodiment, preferably, the upper slot 21 contains a second spring 24. The top of the second spring 24 abuts against the bottom edge of the locking handle 15, so that the bushing 23 can be stably rolled into contact with the top edge of the locking handle 15 and the guide groove 18 through the elastic tension of the second spring 24.

[0024] In this embodiment, preferably, the bottom of the inner cavity of the shift lever 7 is provided with a third spring 29 sleeved on the outside of the locking lever 26. The two ends of the third spring 29 respectively abut against the bottom end of the pull rod 19 and the shoulder of the bottom of the locking lever 26. The locking lever 26 can be pushed downward elastically by the third spring 29, so that the locking lever 26 is stably pressed into the automatic groove 3, and the locking lever 26 is kept stable.

[0025] In this embodiment, preferably, a switch base 5 is provided on one side of the inner cavity of the bottom shell 2. A switch positioning groove 6 corresponding to the automatic point groove 3 is formed in the switch base 5. The switch positioning groove 6 is used to install a contact switch. A shift lever 8 is formed on the bottom surface of the side near the switch base 5 with a shift lever 12 corresponding to the switch positioning groove 6. Specifically, a contact switch is installed in the switch positioning groove 6. The shift lever 12 abuts against the contact switch at different positions when the shift lever 8 is rotated, and shifting gears is performed by opening the contact switch at different positions.

[0026] In this embodiment, preferably, a hinge cavity 9 is provided in the middle of the shift paddle 8, and the shift lever 7 is hinged in the hinge cavity 9 by a central pin 10. A central guide groove 20 is provided at the bottom of the pull rod 19 to slide with the central pin 10. Specifically, the shift lever 7 can swing left and right in the hinge cavity 9 by the central pin 10. The central pin 10 passes through the central guide groove 20 of the pull rod 19 and is engaged with the shift lever 7 and the shift paddle 8 by a shaft hole. By opening the hinge cavity 9 in the middle of the shift paddle 8, the shift lever 7 and the shift paddle 8 are hinged by the central pin 10. The central pin 10 and the central guide groove 20 cooperate to limit the lifting and lowering of the pull rod 19 in both directions. At the same time, since the shift paddle 8 is hinged in the shift housing 1, the shift lever 7 is cross-hinged, which makes it easier to switch between automatic and manual transmission by the shift lever 7.

[0027] In this embodiment, preferably, the bottom surface of the inner shell 2 is provided with a manual slide groove 4 located on one side of the automatic shift groove 3. The manual slide groove 4 cooperates with the locking rod 26 for manual shifting. Specifically, the manual slide groove 4 is grooved along an elliptical linear path, and the depth of the two sides of the manual slide groove 4 gradually decreases, so that the shift lever 7 can be pushed to the middle to reset under the reset action of the third spring 29. The driver presses the locking handle 15 with his thumb, and pulls the locking rod 26 upward through the pull rod 19 to release the locking rod 26. Through the handle composed of the handle shell 13 and the handle cover 14, the shift lever 7 is deflected towards the driver's side and switched to manual gear. The manual gear can be locked by the cooperation of the manual slide groove 4 and the locking rod 26. After manually shifting gears, the shift lever 7 springs back to the middle position to reset by the change in depth of the manual slide groove 4.

[0028] In this embodiment, preferably, a top cover 30 detachably connected to the top of the shifter housing 1 is also included. The top surface of the top cover 30 has a conical limiting hole 31. Specifically, the limiting hole 31 is used to limit the swing of the shift lever 7. A positioning cylinder 33 is sleeved on the top surface of the shifter housing 1. A ball bearing 32 is sleeved on the top of the shift lever 7. The ball bearing 32 contacts the inner top surface of the top cover 30 and the spherical top surface of the positioning cylinder 33. Specifically, a through hole is provided in the middle of the ball bearing 32 for axial engagement with the shift lever 7. The ball bearing 32 is located... Between the top of the positioning cylinder 33 and the inner top surface of the top cover 30, the top of the positioning cylinder 33 forms an outer spherical surface, and the inner top surface of the top cover 30 forms an inner concave spherical surface. The outer spherical surface and the inner concave spherical surface contact the bottom surface and the top surface of the ball bearing 32, respectively. Thus, the opening formed between the shifter housing 1 and the shift lever 7 can be closed by the top cover 30 in conjunction with the positioning cylinder 33 and the ball bearing 32. The ball bearing 32 contacts the positioning cylinder 33 and the top cover 30 through its spherical surface. The ball bearing 32 moves in response to the action of the shift lever 7, improving the stability of the closure.

[0029] Working principle and usage process of this utility model:

[0030] In use, a contact switch for identifying the gear position is installed in the switch positioning slot 6, and a contact switch for identifying automatic and manual modes is installed on the side wall of the shift console 12.

[0031] In automatic mode, pressing the locking lever 15 pushes the upper positioning pin 22 via the guide groove 18, causing the pull rod 19 to move upward. The pull rod 19 then moves the locking lever 26 upward, releasing the locking lever 26 from the automatic point groove 3. The handle composed of the handle housing 13 and the handle cover 14 swings forward or backward, causing the shift lever 7 to swing via the shift block 8. Through the cooperation allowance between the lower positioning pin 27 and the lower guide groove 28, the locking lever 26 exits through one automatic point groove 3 via its tapered end and enters another automatic point groove 3 under the reset action of the third spring 29. After releasing the locking lever 15, under the return action of the first spring 17, the second spring 24, and the third spring 29, the locking lever 26 falls into the automatic point groove 3 of the corresponding gear. At the same time, the contact switch of the previous position is disconnected after the shift table 12 leaves, and the shift table 12 abuts against and opens the contact switch of the next position, realizing automatic gear shifting and locking.

[0032] By pressing the locking handle 15, the guide groove 18 pushes the upper positioning pin 22, causing the pull rod 19 to move upward. The pull rod 19 then causes the locking rod 26 to move upward, releasing the locking rod 26 from the automatic locating groove 3. The handle composed of the handle housing 13 and the handle cover 14 is turned towards the driver's side, causing the locking rod 26 to exit through the automatic locating groove 3 and enter the manual slide groove 4. After releasing the locking handle 15, the locking rod 26 is locked in the manual slide groove 4 under the return action of the first spring 17, the second spring 24 and the third spring 29. At the same time, the shift lever 7 deviates from the shift table 12 and disconnects the contact switch on the side wall of the shift table 12, entering the manual gear position.

[0033] In manual mode, the lever consisting of the handle housing 13 and the handle cover 14 swings forward or backward. Through the shift lever 12 and the contact switches at different positions, the manual gear shift is performed. After manually shifting gears, the shift lever 7 springs back to the middle position to reset due to the change in depth of the manual slide groove 4.

[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
