[0022] The present invention will be further described in detail below in conjunction with specific implementations and with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.

[0023] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts unless otherwise specifically stated.

[0024] like Figures 1 to 10 A shifter and cable comprehensive performance test bench shown in the figure includes a test platform 1, a shifting actuator, a cable vehicle tooling and an adjustable Z-axis module, wherein the shifting actuator, the cable vehicle tooling and the adjustable Z-axis module are arranged on the test platform 1 and fixed on the position on the test platform by a lever pressing block 7.

[0025] The upper surface of the test platform 1 is a working surface, on which the gear selection and shifting actuator, cable vehicle tooling and adjustable Z-axis module are arranged, and the working surface is provided with a plurality of crisscross T-shaped slots 11. The crisscross T-shaped slots 11 are used to divide the working surface of the test platform 1 into a plurality of rectangular blocks. When fixing the shifting actuator, cable tooling, and adjustable Z-axis module components arranged on the test platform 1, one end of the lever pressing block 7 is pressed on the shifting actuator, cable tooling, and adjustable Z-axis module components to be fixed, and the other end is pressed on the working surface. In addition, a through hole 71 is opened in the middle of the lever pressing block 7, and the through hole 71 is adjusted to be directly above the T-slot 11. Then, a T-nut is inserted into the T-slot 11 and slid to a position corresponding to the through hole 71. Then, a bolt is passed through the through hole 71 and screwed into the T-nut below. The bolt is tightened continuously, so that the lever pressing block 7 can press the component to be fixed on the test platform 1 to fix it in place. By pressing multiple lever pressing blocks 7 at different positions of the component to be fixed, the fixing effect of the component to be fixed is improved, and displacement of the component to be fixed can be effectively prevented. The lever pressing block 7 is an L-shaped structure, including a long side and a short side, one end of the long side is pressed on the gear selection and shifting actuator, the cable vehicle tooling and the adjustable Z-axis module, and the lower side of the other end is integrated with the short side, and the lower side of the short side is pressed on the working surface. The through hole 71 is opened on the long side and passes through the upper and lower sides of the long side.

[0026] Recombination Figure 2-Figure 4The shifting actuator includes a base plate 23, a guide rail assembly 242, a sliding assembly, a shifter fixing seat 21, and a driving force assembly. The driving force assembly includes a first longitudinal lifting mechanism, a swing arm 222, a motor assembly 22, a lateral displacement mechanism 221, and a toggle member 226. The base plate 23 is a relatively heavy metal plate, such as a steel plate or an iron plate, which is laid flat on the work surface. The guide rail assembly 242 and the shifter fixing seat 21 are fixed on the upper side. The guide rail of the guide rail assembly 242 is a right-angle guide rail, and the bend of the right-angle guide rail is transitioned with an arc guide rail 241. The shifter fixing seat 21 is fixed to the inner side of the wrap angle of the right-angle guide rail. The sliding assembly 243 is slidably installed on the right-angle guide rail, and a limiter is provided to limit the movement of the sliding assembly 243 in the guide stroke of the guide rail assembly 242, thereby fixing the position of the sliding assembly 243 on the guide rail assembly 242. The first lifting mechanism is installed on the sliding assembly 243, and moves with the displacement of the sliding assembly. It includes a stand 230, an electric screw and a first connecting member 229. The lower end of the stand 230 is fixed on the sliding assembly 243. The electric screw is installed on the stand 230, and drives the first connecting member 229 to move up and down. The first connecting member 229 is also fixed with the motor assembly 22. The output shaft of the motor assembly 22 faces the side of the shifter fixing seat 21, and the output shaft is connected to the lower end of the swing arm 222. The swing arm 222 is driven to swing a certain angle by the rotation of the output shaft. The upper part of the swing arm 222 is also installed with the lateral movement mechanism 221. A second screw rod 223 is installed on the upper part of the swing arm 222, and the lateral movement mechanism 221 is installed on the second screw rod 223 through the second connecting member 231. The second screw rod 223 is driven to rotate by the second eccentric crank 224, thereby adjusting the position of the lateral movement mechanism 221 on the swing arm 222, as a supplement to the electric screw rod, for fine-tuning the position. A third screw rod 227 is also provided on the lateral movement mechanism 221, and one end of the toggle member 226 is installed on the third screw rod 227 through the third connecting member 225, and the other end is connected to a ball head grip assembly (not shown). In this way, by setting a right-angle guide rail, the positions of the first longitudinal lifting mechanism, the swing arm 222, the motor assembly 22, the lateral displacement mechanism 221 and the toggle member 226 can be adjusted according to the product testing requirements by moving the sliding assembly 243 to achieve different performances of the test shifter. For example, the press-fitting equipment and inspection method of the automatic shift operating mechanism assembly disclosed in the existing patent document CN117906971A can only measure the shift force and shift displacement distance of the shifter through the swing and other components of the first device, but cannot measure the overall strength of the shifter. In the present invention, the position of the shift actuator is changed by a right-angle guide rail, thereby changing the force direction of the shifter ball head, and testing the structural strength of the shifter from multiple directions.

[0027] In the above-mentioned embodiment, the first connecting member 229, the second connecting member 231 and the third connecting member 225 are all provided with dovetail grooves, and are respectively connected to the stand, the swing arm and the lateral movement mechanism through the dovetail grooves to form a guide, thereby improving the stability of the movement of the first connecting member 229, the second connecting member 231 and the third connecting member 225. At the same time, in order to prevent the first connecting member 229, the second connecting member 231 and the third connecting member 225 from slipping during use, a locking member is also provided to limit the movement of the first connecting member 229, the second connecting member 231 and the third connecting member 225 and fix them at a predetermined position.

[0028] In the above-mentioned embodiment, the end of the third screw rod 227 is connected to the third eccentric crank handle 228 to facilitate the rotation of the third screw rod 227 .

[0029] Re-read Figure 1 The shifter fixing seat 21 is mounted on the bottom plate 23 by bolts, and includes a first mounting plate 215, a second mounting plate 212 and a fixing seat 211. The first mounting plate 215 is fixed to the bottom plate 23 by bolts, and a first longitudinal strip hole 214 is provided on its plate surface, and the longitudinal position of the shifter fixing seat 21 installed on the bottom plate 23 can be fine-tuned through the first longitudinal strip hole 214. The second mounting plate 212 is fixed to the upper side of the first mounting plate 215, and a first transverse strip hole 213 is provided on its plate surface, and the transverse position of the shifter fixing seat 21 installed on the first mounting plate 215 can be fine-tuned through the first transverse strip hole 213. In this way, through the arrangement of the first longitudinal strip hole 214 and the first transverse strip hole 213, the shifter fixing seat 21 can be fine-tuned in the longitudinal and transverse directions, thereby improving the applicability of the shifter fixing seat 21.

[0030] The shift actuator is used to perform load efficiency test, shift force test, manual mode shift force test, lateral clearance test, handle ball force point stiffness test, static strength test, etc. of the shifter 3. For example, the method of using the shift actuator to test the shift force includes the following steps:

[0031] S101, install the shifter 3 on the top of the shifter fixing seat 21, adjust the position of the driving force assembly installed on the guide rail assembly 242, and then connect the toggle member to the ball head of the shifter through the swing arm 222, the adjusting electric screw rod, the second screw rod 223, and the third screw rod 227;

[0032] S102, continue to adjust the electric screw, the second screw 223, and the third screw 227 to connect the toggle member and the shifter ball head in place, and record the position of the shifter ball head through the sensor;

[0033] S103, using the power outputted by the motor assembly 22 to drive the swing arm 222 to move, so that the toggle member 226 applies the thrust required by the test shift force to the shifter ball head, and observe whether the shifting of the joystick 31 is smooth. For example, the shifting force F(PR): 7±2N; F(RN): 7±2N; F(ND): 7±2N; F(DS): 7±2N; F(DM): 7±2N. F(RN) represents the shifting force from R gear to N gear.

[0034] After completing the shifting force test, disassemble the toggle member 226 and the shifter ball head, loosen the lever pressure block 7 that presses the driving force assembly, push the driving force assembly to move along the stroke of the guide rail assembly 242, so that the position of the driving force assembly changes by 90° and then re-fix the position of the driving force assembly, then connect the toggle member 226 to the ball head of the shifter 3 and fix it in place by adjusting the swing arm 222, the electric screw, the second screw 223, and the third screw 227, and continue to record the position of the shifter ball head; use the power output by the motor assembly 22 to drive the swing arm 222 to drive the toggle member 226 to push the ball head to move perpendicular to the shifting direction (the moving direction is perpendicular to the moving direction of the shifter lever for testing the shifting force), obtain the moving distance of the shifter lever 31 through the sensor, and measure the lateral clearance data.

When in use, the clamping joints provided at both ends of the flexible shaft of the cable are respectively clamped on the first limit pile 44 and the second limit pile 43, and the turning angle of the cable is adjusted by adjusting the positional relationship between the cornering device 42, the first limit pile 44 and the second limit pile 43 installed on the test platform 1, thereby simulating different real vehicle assembly conditions and improving functionality and adaptability. Moreover, the operation on the test platform 1 can meet the cable test of most models, and has a wide range of applications. The pulling pile 45 is installed on the side of the first limiting pile 44, and is used to connect one end of the steel wire rope of the cable 5. Both ends of the steel wire rope of the cable 5 are provided with a connection structure for connecting the pulling pile 45 or the shifter 3.
