[0002] A car is a self-powered land vehicle, mainly used to carry people or goods. It is one of the most important and common means of transportation in modern society. A manual transmission car, also known as a manual transmission car, is a car that changes the gear ratio and changes the speed by manually operating the gear lever to change the gear meshing position in the transmission. It usually has five forward gears (first, second, third, fourth, and fifth gears) and one reverse gear. It has the advantages of simple structure, reliability, low maintenance cost, and high transmission efficiency.

[0003] In order to help drivers, especially beginners and drivers who need to improve their shifting skills, become familiar with the shifting operation of manual transmission cars, master the correct shifting timing and skills, and improve driving skills and safety, manual transmission car shifting simulation training is needed. Through simulation training, drivers can repeatedly practice shifting operations without actually driving the car, reducing operational errors and safety hazards in actual driving. Traditional simulated shifting training equipment is usually a simple gear lever and clutch structure. After the trainee steps on the clutch, the gear lever can be operated to shift gears. Although the trainee can become familiar with the shifting operation, since it is a simulation training, it is not equipped with a gearbox and an engine, and it is difficult to judge whether the gear shift is successful, which easily leads to the trainee developing bad driving habits of random shifting and incomplete gear engagement.

[0036] Compared with the prior art, the present invention has at least the following beneficial effects:

[0037] In the above scheme, by setting up the oil cylinder, wheel shell and connecting mechanism, the driving trainee can operate the shift lever to push along the gear slot to simulate gear shifting. During the gear shifting process, the driving piston head is moved to force the oil in the oil cylinder to circulate, producing a damping effect. Coupled with the mechanical engagement effect produced by the gear selection ball embedded in the arc groove during the gear selection process, it can more realistically assist in simulating the perception of the gear shifting process of manual transmission car driving.

[0038] By setting the clutch plate and the locking block and cooperating with the pushing mechanism, when the trainee changes gears, the gear shifting operation can only be performed when the clutch pedal is pressed and the locking block is separated from the clutch plate. After the clutch pedal is released, the locking block fits with the clutch plate to lock the clutch plate, and then locks the impeller in the wheel housing. After the impeller is locked, the oil at both ends of the cylinder is restricted from flowing along the oil pipe, and resistance is generated to the movement of the piston head in the cylinder, thereby locking the gear position and helping trainees develop the driving habit of changing gears by pressing the clutch.

[0039] By setting the cursor plate and the photosensor and cooperating with the shift ball and the shift fork, when pushing the shift lever to shift gears, the shift ball at the top of the driven lever squeezes and triggers the touch pressure sensor in the corresponding arc groove, which can confirm the shifted gear. At the same time, the piston head squeezes the oil delivery to force the impeller to drive the clutch plate to rotate. The multiple cursor plates on the clutch plate rotate synchronously, and the cursor plates reflect external light and are read by the photosensor. By calculating the number of cursor plates read by the photosensor, it can be determined whether the gear conversion is completed, thereby avoiding the gear disengagement during actual driving. In addition, after the gear shift is completed and the clutch is released, the gear is locked, and the multiple cursor plates on the clutch plate are covered in the assembly cavity on the locking block, which can protect the photosensitive sensor and the cursor plate from light, reduce external interference, and improve durability.

[0040] This technical solution has a reasonable overall structure. On the basis of assisting in simulating the actual driving gear shifting perception process of a manual transmission car, it integrates the gear confirmation, gear shifting judgment and gear locking functions. It is also highly durable and can more reasonably and comprehensively assist driving trainees in simulating the manual transmission car driving gear shifting process and forming good driving gear shifting habits.

[0064] like Figure 1 , Figure 2 and Figure 7As shown, the embodiment of the present invention provides a multi-gear stroke auxiliary action structure for a manual gear push rod, comprising a main housing 1 and a shift lever 4, wherein a gear selection panel 3 is provided at the top of the main housing 1, and a gear slot 5 consistent with the gear of a manual gear car is provided on the gear selection panel 3, and the shift lever 4 is arranged through the gear slot 5, and the shift lever 4 is pushed along the gear slot 5 by operating the shift lever 4 to simulate the gear shifting operation of a manual gear car, and is used for simulation training of manual gear car driving trainees. An oil cylinder 6 is installed at the bottom of the main housing 1, and specifically, the oil cylinder 6 is horizontally penetrated and fixed at the bottom of the main housing 1, and a shell seat 2 is also installed at the bottom of the main housing 1, and the oil cylinder 6 is covered therein for protection; a pair of piston heads 23 that can move synchronously are installed in the oil cylinder 6, and the space between the piston head 23 and the inner end wall of the oil cylinder 6 is filled with oil, and a longitudinal linkage mechanism is provided between the oil cylinder 6 and the bottom end of the shift lever 4, and the shift lever 4 shifts gears through the longitudinal linkage mechanism to drive a pair of piston heads 23 to perform piston movement in the oil cylinder 6.

[0065] like Figures 2 to 8 As shown, a piston connecting rod 22 is connected between a pair of piston heads 23, a connecting ear block 12 is provided in the middle of the piston connecting rod 22, a through groove 11 is provided on the top wall of the oil cylinder 6, and the connecting ear block 12 passes through the through groove 11 and extends out of the oil cylinder 6; the longitudinal connecting mechanism includes a driven rod 13 movably hinged at the top of the connecting ear block 12 and a shift fork 15 fixed to the bottom end of the shift lever 4, wherein the driven rod 13 and the connecting ear block 12 are specifically sliding hinged, specifically, a guide groove is provided at the bottom of the driven rod 13, and the hinge shaft of the connecting ear block 12 passes through the guide groove; the side surface of the shift fork 15 is a fan-shaped structure, and the front face of the shift fork 15 is an inverted U-shaped structure, the shift fork 15 is movably sleeved and matched with the top of the driven rod 13, and a positioning ball 17 is provided at the position of the shift lever 4 near the shift fork 15, and a sleeve plate 16 is sleeved on the positioning ball 17, and the sleeve plate 16 is fixed in the main housing 1, and a sleeve plate 16 is provided on the sleeve plate 16 The ball 17 is adapted to the slot 20, and the shift rod 4 can rotate 360° by nesting the positioning ball 17 and the sleeve plate 16. A hinge sleeve 14 is provided at a position near the top of the driven rod 13, and the hinge sleeve 14 is rotatably assembled in the main housing 1. The rotation direction of the hinge sleeve 14 is consistent with the length direction of the cylinder 6. During the operation of the shift rod 4 to shift gears along the gear slot 5, when the shift rod 4 is pushed to select gears (that is, when the shift rod 4 is pushed to align with the gear slot 5 to be shifted), the shift fork 15 at the bottom end of the shift rod 4 swings longitudinally, and when the shift rod 4 is pushed into the gear slot 5 to engage the gear, the shift fork 15 at the bottom end of the shift rod 4 swings laterally, pushing the driven rod 13 to rotate and swing along the hinge sleeve 14. The driven rod 13 rotates and swings, and the sliding hinge of the driven rod 13 and the connecting ear block 12 is utilized to push the piston connecting rod 22 to drive a pair of piston heads 23 to move (perform piston motion) in the cylinder 6.

[0066] like Figure 2 and Fig.11As shown, the bottom of the main housing 1 is equipped with a wheel shell 7, and an impeller 29 is installed in the wheel shell 7. The wheel shell 7 and both ends of the oil cylinder 6 are connected with oil pipes 8. The movement of a pair of piston heads 23 forces the oil in the oil cylinder 6 to circulate. Specifically, the oil is transported from the squeezed end of the oil cylinder 6 along the oil pipe 8 through the wheel shell 7, and then circulated to the suction end of the oil cylinder 6. In this process, the circulating flow of the oil forces the impeller 29 in the wheel shell 7 to rotate, generating a damping effect, wherein, as Figure 8 As shown, an air ring, a sealing ring and an oil ring are nested on the piston head 23 to ensure that the inner chamber of the oil cylinder 6 is sealed to prevent oil leakage.

[0067] like Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 as well as Fig.14As shown, a shift selection ball 21 is arranged at the top of the driven rod 13, and a plurality of shell barrels 37 are arranged along a sector-shaped trajectory on both side walls of the shift selection fork 15. The number of the shell barrels 37 matches the number of the shift slots 5 on the shift selection panel 3. The center of the sector-shaped trajectory of the plurality of shell barrels 37 coincides with the rotation axis of the shift lever 4. A tube body 38 is movably penetrated at one end of each shell barrel 37 facing the shift selection fork 15. One end of the tube body 38 is located in the shell barrel 37 and is provided with a baffle 39. A second spring 43 is arranged between the baffle 39 and an end wall of the shell barrel 37 away from the shift selection fork 15. The tube body 38 The other end of the tube 38 penetrates through the side wall of the shift fork 15 and extends into the shift fork 15 and is connected to a gear determination block 40. The gear determination block 40 is provided with an arc groove 41 that can accommodate the gear selection ball 21. The two side edges of the gear determination block 40 facing the arc groove 41 are provided with arc chamfers. A touch pressure sensor 42 is installed in the tube body 38. The touch pressure end of the touch pressure sensor 42 penetrates through the gear determination block 40 and extends into the arc groove 41. When the shift lever 4 is operated to shift gears, when the shift lever 4 is pushed to select gears (that is, when the shift lever 4 is pushed to align with the gear slot 5 to be shifted), the selector 4 is pressed. The shift fork 15 swings longitudinally, and the shift ball 21 at the top of the driven rod 13 is embedded in the arc groove 41 of the corresponding pair of gear determination blocks 40 in the shift fork 15. In this process, under the push of the elastic force of the second spring 43, a mechanical bouncing feeling can be generated, and the damping effect produced by the oil circulation can more realistically assist in simulating the shifting process of manual transmission car driving, so as to provide driving trainees with manual transmission car driving shifting simulation training. In addition, the shift lever 4 is pushed into the gear slot 5 to engage the gear. When the shift fork 15 at the bottom of the shift lever 4 swings horizontally, the selector ball 21 at the top of the driven rod 13 The squeezing of the shift ball 21 triggers the touch pressure sensor 42 in the corresponding arc groove 41. The touch pressure sensor 42 obtains the squeezing signal, can confirm the shifted gear, and provide gear feedback. The height of the gear determination block 40 is greater than the diameter of the shift selection ball 21, to ensure that when the gear determination block 40 swings with the shift selection fork 15 to shift gears, the shift selection ball 21 can always be located in the arc groove 41 of the gear determination block 40. Preferably, the shift selection ball 21 can be designed as a long strip structure (only the spherical shape is shown as an example in the drawings in the specification), so as to prevent the shift selection ball 21 from escaping from the arc groove 41.

[0068] like Figure 2 , Figure 3 , Figure 5 , Figure 7 as well as Figures 8 to 13As shown, a clutch disc 9 and a locking block 10 are assembled on one side of the wheel shell 7, and the clutch disc 9 is coaxially rotatably assembled and connected with the impeller 29. A pushing mechanism for driving the locking block 10 to move close to the wheel shell 7 and limit the rotation of the clutch disc 9 is provided on the main housing 1; a main shaft rod 25 is fixed to the bottom of the outer wall of the main housing 1, and the wheel shell 7 is fixedly sleeved on the main shaft rod 25. The clutch disc 9 and the locking block 10 are both movably sleeved on the main shaft rod 25, wherein the clutch disc 9 is rotatably sleeved on the main shaft rod 25, and the clutch disc 9 can follow the impeller 29 The locking block 10 is slidably mounted on the main shaft 25 relative to the rotation of the main shaft 25. The sliding nesting portion of the main shaft 25 and the locking block 10 is set in a flat shape to limit the rotation of the locking block 10 on the main shaft 25. The locking block 10 is located on the side of the clutch disc 9 away from the wheel housing 7. The locking block 10 is provided with a plurality of locking protrusions 33 on the side facing the clutch disc 9. The plurality of locking protrusions 33 are evenly distributed in an annular shape. The clutch disc 9 is provided with locking grooves 34 that are equal in number to the locking protrusions 33 and are plug-fitted. The structure includes an electric push rod 19 assembled on the outer wall of the main housing 1 and a fork 18 fixed to the telescopic end of the electric push rod 19. The fork 18 is set to a U-shaped structure. A slot 26 is opened on the outer wall of the locking block 10. The fork 18 of the U-shaped structure is sleeved and matched with the slot 26. The electric push rod 19 is connected to the clutch pedal control of the simulated driving system. When the clutch pedal is not stepped on, the electric push rod 19 shrinks, forcing the locking block 10 to fit with the clutch disk 9, and a plurality of locking protrusions 33 on the locking block 10 are engaged with the clutch disk 9. The locking groove 34 is engaged to lock the clutch disc 9, and then to lock the impeller 29 in the wheel housing 7. After the impeller 29 is locked, the oil at both ends of the cylinder 6 is restricted from flowing along the oil pipe 8, and resistance is generated to the movement of the piston head 23 in the cylinder 6, thereby achieving gear locking. After the clutch is pressed, the electric push rod 19 is controlled to start pushing the shift fork 18 to drive the locking block 10 away from the clutch disc 9. At this time, the locking block 10 and the clutch disc 9 are in a separated state, and the shift lever 4 can be operated to start shifting gears, which helps students develop a driving habit of shifting gears by pressing the clutch. Among them, an end plate 27 is fixed to the end of the main shaft rod 25 away from the main shell 1, and a first spring 28 is mounted on the main shaft rod 25 between the end plate 27 and the locking block 10. After the electric push rod 19 contracts and forces the locking block 10 and the clutch disk 9 to fit together, the first spring 28 can apply elastic force to the locking block 10, so that the locking block 10 remains in a state of fitting with the clutch disk 9, avoiding continuous contraction and force of the electric push rod 19.

[0069] like Figure 2 , Figure 3 , Figure 5 , Figure 7 as well as Figures 8 to 13As shown, a plurality of cursor plates 35 are provided on one side of the clutch disc 9 facing the locking block 10, and the plurality of cursor plates 35 are distributed in a circular array. A photosensitive sensor 32 aligned with the circular tracks of the plurality of cursor plates 35 is mounted on the locking block 10, and the photosensitive sensor 32 can sense and obtain the reflection information of the cursor plates 35. In the simulated gear shifting process, the oil circulation in the oil cylinder 6 forces the impeller 29 to rotate, and the impeller 29 drives the clutch disc 9 to rotate, and the plurality of cursor plates 35 on the clutch disc 9 rotates. By recording the number of rotations of the cursor plates 35 read by the photosensitive sensor 32, it can be used to determine whether the gear shift is in place, and avoid the gear shifting phenomenon when the gear is not fully engaged. The simulation is more realistic, and good driving and shifting habits can be cultivated.

[0070] like Figure 2 , Figure 3 , Figure 5 , Figure 7 as well as Figures 8 to 13 As shown, the locking block 10 is provided with an assembly cavity 31 on the side facing the clutch disk 9, and the photosensitive sensor 32 is assembled in the assembly cavity 31. The pushing mechanism pushes the locking block 10 to limit the rotation of the clutch disk 9, and can simultaneously arrange multiple cursor plates 35 sealing covers in the assembly cavity 31. The clutch disk 9 is also provided with an optical light-absorbing paper 36 on the side facing the locking block 10. The setting of the light-absorbing paper 36 can make the cursor plate 35 photosensitive sensor 32 read the cursor plate 35 more accurately and reduce light interference. The side facing the locking block 10 is set as a mirror surface, and the side of the cursor plate 35 facing the locking block 10 is gradually concave from both ends toward the middle. The concave structure makes the mirror reflection of the cursor plate 35 The light can be focused in the assembly cavity 31 and sensed by the photosensor 32, thereby improving the reading sensitivity of the cursor plate 35. When the clutch pedal is pressed to shift gears, the locking block 10 and the clutch disc 9 are separated. At this time, the cursor plate 35 on the clutch disc 9 can reflect external light into the assembly cavity 31 and be sensed by the photosensor 32. As the cursor plate 35 rotates, it is used to determine whether the gear is fully engaged. When the clutch pedal is released, the locking block 10 and the clutch disc 9 are locked, and the multiple cursor plates 35 on the clutch disc 9 are covered in the assembly cavity 31 on the locking block 10, which can protect the photosensor 32 and the cursor plate 35 from light, reduce external interference, and improve durability.

[0071] The calculation method to determine whether the gear shift is in place is as follows:

[0072] The compression chamber 24 is located between the piston head 23 in the oil cylinder 6 and the end wall of the oil cylinder 6. The average oil storage volume of the two compression chambers 24 is L1.

[0073] There are multiple delivery chambers 30 between the impeller 29 and the inner wall of the wheel shell 7, and the oil storage capacity of each delivery chamber 30 is L2;

[0074] The number of the delivery chambers 30 is a;

[0075] The number of cursor plates 35 is b;

[0076] The distance between the shift selection panel 3 and the positioning ball 17 is h1;

[0077] The distance between the shift selection fork 15 and the positioning ball 17 is h2;

[0078] The distance between the shift selection fork 15 and the articulated shaft sleeve 14 is h3;

[0079] The distance between the connecting ear block 12 and the articulated sleeve 14 is h4;

[0080] The distance between the top of the shift lever 4 and the positioning ball 17 is h5;

[0081] The depth of the gear slot 5 is h6;

[0082] The distance the piston head 23 moves during gear shifting is h7;

[0083] The cross-sectional area of ​​the compression chamber 24 is s;

[0084] The average length of the two compression chambers 24 is h8;

[0085] Where: h1=h2=h3=h4 / 2

[0086] h5=2*h4 (the force-applying arm is twice the force-bearing arm, which can reduce resistance and avoid shifting effort)

[0087] h7=2*h6

[0088] L1=h8*s

[0089] L3=h7*s=2*h6*s=2*h6*L1 / h8

[0090] S=[L3 / (L2*a)]*b

[0091] L3 is the compression amount of the compression chamber 24 when shifting gears, and S is the number of cursor plates 35 that the photosensor 32 needs to read when shifting gears.

[0092] Only when S is within the calculated setting range (the allowable error is 5), the gear shift is determined to be in place, otherwise it is determined that the gear shift is not completed; in addition, the photosensor 32 reads the cursor plate 35 and the calculation should start from the time when the shift lever 4 is pushed to select the gear (that is, when the shift lever 4 is pushed to align with the gear slot 5 to be shifted, before the touch pressure sensor 42 obtains the pressure signal).

[0093] The working principle of the technical solution provided by the present invention is as follows:

[0094] When in use, the driving trainee operates the shift lever 4 to push along the gear slot 5 to simulate the gear shifting and selecting of a car driving. When simulating gear shifting, the trainee steps on the clutch pedal to control the electric push rod 19 to start pushing the shift fork 18 to drive the locking block 10 away from the clutch plate 9. At this time, the locking block 10 and the clutch plate 9 are in a separated state, and the gear shifting begins. The shift lever 4 is pushed to align with the gear slot 5 to be shifted, and the gear selection fork 15 at the bottom of the shift lever 4 swings longitudinally. The gear selection ball 21 at the top of the driven rod 13 is embedded in the arc groove 41 of a pair of gear determination blocks 40 corresponding to the gear selection fork 15. Then the shift lever 4 is pushed into the gear slot 5 to engage the gear, and the shift lever The shift fork 15 at the bottom of the shift fork 15 swings laterally, pushing the driven rod 13 to rotate and swing along the hinge sleeve 14. In this process, the shift ball 21 at the top of the driven rod 13 squeezes and triggers the touch pressure sensor 42 in the corresponding arc groove 41 to confirm the shift position. The driven rod 13 rotates and swings to push the piston connecting rod 22 to drive a pair of piston heads 23 to move in the oil cylinder 6. The moving direction is opposite to the lateral swinging direction of the shift fork 15. The movement of the pair of piston heads 23 forces the oil in the oil cylinder 6 to circulate. Specifically, the oil is transported from the squeezed end of the oil cylinder 6 along the oil pipe 8 through the wheel housing 7, and then circulated to the suction end of the oil cylinder 6. In this process, The circulating flow of oil forces the impeller 29 in the wheel housing 7 to rotate. The damping effect produced during the oil circulation process, coupled with the mechanical engagement effect produced by the gear selection ball 21 embedded in the arc groove 41 during the gear selection process, can more realistically assist in simulating the perception of the manual transmission car driving shift process. In addition, the impeller 29 drives the clutch plate 9 to rotate, and the multiple cursor plates 35 on the clutch plate 9 rotate synchronously. Since the locking block 10 and the clutch plate 9 are separated, the cursor plates 35 can reflect external light and be read by the photosensor 32. Then, by calculating the number of cursor plates 35 read by the photosensor 32, it can be used to determine whether the gear is switched. Completed. After the gear shift is completed, release the clutch pedal, the electric push rod 19 contracts, and forces the locking block 10 to fit with the clutch disc 9. At this time, the locking protrusions 33 on the locking block 10 are engaged with the locking grooves 34 on the clutch disc 9, locking the clutch disc 9, and then locking the impeller 29 in the wheel housing 7. After the impeller 29 is locked, the oil at both ends of the cylinder 6 is restricted from flowing along the oil pipe 8, and resistance is generated to the movement of the piston head 23 in the cylinder 6, thereby realizing gear locking, and the multiple cursor plates 35 on the clutch disc 9 are covered in the assembly cavity 31 on the locking block 10, which can protect the photosensitive sensor 32 and the cursor plate 35 from light and reduce external interference.
