Description

Technical Field

[0001] This invention relates to the field of gear shifting mechanism assembly technology, specifically a gear shifter. Background Technology

[0002] The shifter assembly is used in conjunction with the transmission in a vehicle to change the gears of the transmission. For example, the shifter assembly can be used to shift an automatic transmission to multiple automatic modes, such as parking, reverse, neutral, and drive. The shifter assembly can also be used to shift an automatic transmission to a manual mode similar to a manual transmission, where the driver can manually shift the automatic transmission between gears once in manual mode.

[0003] The shifter assembly includes a shifter that operates along a first path between multiple automatic modes. The shifter then moves into a second path for switching from automatic to manual mode. Once in manual mode, the shifter operates along the second path in a back-and-forth manner to manually change gears within the automatic transmission. The second path is typically parallel to and spaced apart from the first path or tangential to the first path. In either case, the shifter must move laterally relative to the first path to complete the manual gear change within the automatic transmission. This lateral movement of the shifter occupies additional space within the vehicle, which is undesirable. The required lateral movement also results in additional complex components in the shifter assembly to allow for lateral shifting while restricting other movements. Therefore, there is an opportunity to provide an improved shifter assembly. Summary of the Invention

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0021] Reference Figures 1-9This technical solution provides a gear shifter, which includes a mounting base 1. A control mechanism 2 is mounted on the top of the mounting base 1. The control mechanism 2 includes a mounting bracket 201, a placement block 204, and a rotating shaft 206. The mounting bracket 201 is mounted on the top of the mounting base 1 and has an L-shaped structure. The surface of the mounting bracket 201 is provided with a first mounting groove 202. Multiple first mounting grooves 202 are provided, and first bolts 203 are installed in the internal threads of the multiple first mounting grooves 202. The operator can fix the mounting bracket 201 on the top of the mounting base 1 by means of the first bolts 203.

[0022] The mounting bracket 201 provides support for the entire control mechanism 2. Due to the first bolt 203, the operator can install the entire control mechanism 2 at any position in the operating space, which is conducive to improving the human-machine relationship. The placement block 204 is fixedly installed on the inner side of the mounting bracket 201. There are two placement blocks 204. The top of the two placement blocks 204 is equipped with a rotating cylinder 205. Rotating grooves are opened on both sides of the rotating cylinder 205. The rotating shaft 206 is fixedly installed on the side of the mounting bracket 201 by a nut. The rotating shaft 206 passes through the inner side of the mounting bracket 201 and is rotatably connected to the rotating cylinder 205.

[0023] The end of the rotating shaft 206 is inserted into the rotating groove of the rotating cylinder 205 to achieve a rotating connection between the rotating shaft 206 and the rotating cylinder 205. Since the bottom of the rotating cylinder 205 has a notch that matches the side of the placement block 204, the rotating cylinder 205 remains stable on the top of the placement block 204 and will not rotate. A U-shaped rod 207 is fixedly installed on the top of the mounting bracket 201. The right placement block 204 is installed inside the U-shaped rod 207. The bending angle of the entire U-shaped rod 207 matches the outer contour of the rotating cylinder 205. The rotating cylinder 205 can be stabilized in the left and right directions by the U-shaped rod 207. A connecting piece 208 is fixedly installed on the surface of the rotating cylinder 205.

[0024] There are two connecting pieces 208, and an outer cylinder 209 is fixedly installed between the two connecting pieces 208. The outer cylinder 209 can be fixedly installed on the surface of the rotating cylinder 205 through the two connecting pieces 208. The outer cylinder 209 protects the entire control mechanism 2 from external collisions that could reduce the control accuracy of the entire shifter. A connecting rod 210 is movably installed on the right end of the rotating cylinder 205. The end of the connecting rod 210 is fixedly connected to a first universal ball 211. The end of the first universal ball 211 is movably connected to the shifting mechanism 3. By operating the shifting mechanism 3, the first universal ball 211 can drive the connecting rod 210 to rotate and slide inside the rotating cylinder 205.

[0025] Reference Figures 1-9Based on the same concept as Embodiment 1 above, this embodiment also proposes a shifting mechanism 3 including a first universal joint 301, a connecting member 304 and a stop bar 306. The first universal joint 301 is movably connected to the first universal ball 211. A connecting post 302 is fixedly installed on the top of the first universal joint 301. A mounting hole 303 is opened on the top of the connecting post 302. The bottom of the connecting member 304 is movably connected to the mounting hole 303. A threaded tube 305 is fixedly installed on the top of the connecting member 304. A threaded rod 307 is installed on the bottom of the stop bar 306. The threaded rod 307 is threadedly connected to the threaded tube 305. A handle 308 is threadedly connected to the top of the stop bar 306.

[0026] The operator can change the handle 308 by rotating it, or change the entire stop lever 306 to different lengths by rotating it, in order to adapt to different operating space requirements. The operator shifts gears by changing the stop lever 306, which drives the threaded rod 307 to move. The movement of the threaded rod 307 drives the movement of the threaded tube 305, which in turn drives the movement of the connector 304, which in turn drives the movement of the connecting post 302.

[0027] The movement of the connecting column 302 drives the movement of the first universal joint 301, which in turn drives the movement of the first universal ball 211. This, in turn, drives the connecting rod 210 to move inside the rotating cylinder 205. Consequently, the entire shifting mechanism 3 can drive the control mechanism 2 to move. The movement of the control mechanism 2, in turn, ensures the accuracy of the shifting mechanism 3. The connection structure between the control mechanism 2 and the shifting mechanism 3 is simple and uses industry-standard joint bearings, which makes the entire shifter more precise and provides a better shifting feel.

[0028] Reference Figures 1-9 Based on the same concept as Embodiment 1 above, this embodiment also proposes a surface sliding mounting control mechanism 4 for the outer cylinder 209. The control mechanism 4 includes a connecting block 401, which is movably connected to the outer cylinder 209. The connecting block 401 can rotate the entire control mechanism 4 on the rotation track of the outer cylinder 209. Fixing holes 402 are provided on both sides of the connecting block 401. A second bolt 403 is installed inside the front fixing hole 402. The connecting block 401 is fixedly connected to a first mounting plate 404 by the second bolt 403. A fixing column 405 is fixedly installed on the side of the first mounting plate 404.

[0029] A baffle 406 is fixedly installed at the end of the fixed post 405, and a return spring 407 is sleeved on the surface of the fixed post 405. The return spring 407 is an essential device in the process of shifting gears in a car. Its main function is to fix the left and right positions of the gear lever 306 when the gear lever 306 is in the neutral position. It can also ensure that the gear lever 306 can accurately lock the gears when shifting gears, so as to avoid inaccurate shifting or shaking, and make the whole shifting process smoother.

[0030] The return spring 407 is slidably connected to the first mounting plate 404 and the stop bar 306 respectively. The rear part of the connecting block 401 is fixedly installed with the second mounting plate 408 by the third bolt. The side of the second mounting plate 408 is fixedly installed with the connecting hinge seat 409. The inside of the connecting hinge seat 409 is fixedly installed with the first hinge rod 410 by the nut. The end of the first hinge rod 410 is fixedly installed with the second universal ball 411. The surface of the second universal ball 411 is movably installed with the second universal shaft 412. The bottom of the second universal shaft 412 is fixedly connected with the first control rod 413.

[0031] The operator operates the stop lever 306, which causes the entire control mechanism 4 to rotate. The rotation of the control mechanism 4 causes the connecting hinge seat 409 to rotate. The rotating connecting hinge seat 409 can pull the first hinge rod 410 inside the connecting hinge seat 409 to rotate as a whole. The rotating first hinge rod 410 can cause the second universal ball 411 to move up and down. The up and down moving second universal ball 411 causes the first control lever 413 to move up and down.

[0032] The movement of the first control lever 413 can cause the hydraulic oil pipe to drive the gearbox to perform gear shifting operations. The entire control mechanism 4 has a compact structure, occupies a small area, and can be freely arranged in any position in the operating space, which makes it easier to improve the human-machine relationship. Furthermore, the entire gear shifter can be arbitrarily combined by disassembling the connecting block 401, or different shifting logics can be achieved by replacing the parts of the gear shifter. The entire gear shifter has a modular design, and each module can be disassembled. Moreover, the entire gear shifter is easy to fix and is suitable for different models and different spatial usage scenarios.

[0033] Reference Figures 1-9 Based on the same concept as Embodiment 1 above, this embodiment also proposes that a second hinge seat 5 is fixedly installed on the side of the connector 304. The operation of the stop bar 306 by the operator can directly affect the spatial position of the connector 304. The change in the spatial position of the connector 304 can control the spatial position of the second hinge seat 5. A second hinge rod 6 is fixedly installed inside the second hinge seat 5 by a nut. A third universal ball 7 is fixedly installed at the end of the second hinge rod 6.

[0034] When the spatial position of the second hinge seat 5 changes, it further drives the rotation of the second hinge rod 6. Since the end of the second hinge rod 6 is fixedly installed with the third universal ball 7, and the surface of the third universal ball 7 is movably installed with the third universal shaft 8, the rotation of the second hinge rod 6 can drive the third universal ball 7 to rotate inside the third universal shaft 8, and can pull the third universal shaft 8 to move up and down.

[0035] The bottom of the third universal joint 8 is fixedly installed with a second control lever. The third universal joint 8 can drive the second control lever to move up and down. The up and down movement of the second control lever can drive the hydraulic oil pipe at its bottom to control the gearbox. The top of the connecting block 401 is fixedly connected to the fixing plate 10 by the fourth bolt. The surface of the fixing plate 10 is provided with a shift slot 11. The shift slot 11 is slidably connected to the threaded pipe 305. When the operator performs the shifting operation on the shift lever 306, the shift lever 306 can slide inside the shift slot 11, thereby driving the control mechanism 2 and the shifting mechanism 3 to perform the shifting operation.

[0036] Specifically, the working process or working principle of this gear shifter that can be precisely controlled is as follows: First, the operator can install the mounting base 1 inside the operating space according to different operating spaces. Then, the entire mounting frame 201 is installed on the top of the mounting base 1 by the first bolt 203. Then, the rotating shaft 206 is installed inside the mounting frame 201 by the nut. After the rotating shaft 206 is installed, the operator can install the entire control mechanism 2 on the top of the mounting frame 201. Then, the operator operates the handle 308, and the handle 308 drives the gear lever 306 to move.

[0037] The rotation of the shift lever 306 causes the return spring 407 to generate elastic potential energy, which fixes the left and right positions of the shift lever 306 when it is in the neutral position. It also allows the shift lever 306 to accurately lock the gear during shifting, avoiding inaccurate shifting or vibration, making the entire shifting process smoother. The shift lever 306 drives the threaded rod 307 to move.

[0038] The moving threaded rod 307 drives the threaded tube 305 to move, the movement of the threaded tube 305 drives the connector 304 and the connecting post 302 to move, the movement of the connecting post 302 drives the first universal joint 301 to move, and the movement of the first universal joint 301 drives the first universal ball 211 to move.

[0039] The movement of the first universal ball 211 causes the connecting rod 210 to rotate and slide inside the rotating cylinder 205. The movement of the connecting piece 304 causes the second hinge seat 5 to move. The movement of the second hinge seat 5 causes the second hinge rod 6 to move. The movement of the second hinge rod 6 causes the third universal ball 7 to move. The movement of the third universal ball 7 causes the third universal shaft 8 to move up and down. The up and down movement of the third universal shaft 8 causes the second control rod to move up and down. The up and down movement of the second control rod causes the hydraulic oil pipe to perform gear shifting operation on the gearbox.

[0040] When the shift lever 306 rotates left and right inside the shift slot 11, it drives the entire control mechanism 4 to rotate. The rotation of the control mechanism 4 causes the connecting block 401 to slide on the surface of the outer cylinder 209. The sliding of the connecting block 401 on the outer cylinder 209 drives the second mounting plate 408 to move. The movement of the second mounting plate 408 drives the connecting hinge seat 409 to move. The movement of the connecting hinge seat 409 drives the first hinge rod 410 to move. The movement of the first hinge rod 410 drives the second universal ball 411 to rotate inside the second universal shaft 412. The second universal shaft 412 moves up and down under the drive of the second universal ball 411. The up and down movement of the second universal shaft 412 drives the first control lever 413 to move up and down, so that the hydraulic oil pipe at the bottom of the first control lever 413 can control the gearbox.
