Description
Technical Field
The utility model relates to the technical field of automobile driving simulators, in particular to a manual gear shifting mechanism of a driving simulator.
Background
At present, in order to simulate two hand feelings of damping and suction during gear engaging and gear disengaging, a manual gear shifting mechanism of an automobile driving simulator in China is generally realized by adopting a component comprising a spring, a steel ball and a steel ball limiting groove. The hand feeling of the gear fed back by the structure is not real enough, and the structure mainly has three defects: 1. the feedback force to the driver is far smaller than that of a real vehicle; 2. the fed-back gear engaging hand feeling is far away from the real vehicle, and the gear engaging hand feeling of the real vehicle is not smooth and smooth, but is hard and mechanical; 3. when the gear is engaged, the gear has obvious abnormal rattle and rattle. It can only meet the most basic functional requirements, namely damping and suction hand feel when engaged. But the feedback hand feel is far different in all aspects compared with the real vehicle.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following is further described in connection with a patent document to which the present invention relates. The patent publication No. CN109185442A discloses a manual-automatic integrated gear shifting device of a driving simulator, and the structural principle of the feedback hand feeling of gear engagement and gear disengagement is explained with reference to fig. 1.
The hand feeling feedback mechanism in fig. 1 mainly comprises a steel ball limit groove 17, a steel ball 18, a spring 19, a screw plug 20 and a swing arm 21.
The hand feeling feedback principle of the gear mechanism is as follows: when the driver performs a shift operation or a gear-off operation, the swing arm 21 rotates together with the shift lever about the lower rotation shaft thereof. At this time, the 18 steel balls roll from one groove of the 17 steel ball limiting grooves to the other groove. In the process, the steel ball 18 rolls out of the existing limit groove, and the spring 19 can apply resistance to the rolling-out process; when the steel ball 18 rolls into the other limit groove, the spring 19 applies pushing force to the rolling process. Therefore, the driver can feel the damping feeling and the suction feeling in the gear shifting process.
From the above description of the principle, it is clear that: 1. the hand feeling of damping and suction when the gear is shifted or not is provided by the elastic force of the 19 spring. The space of the structure is very narrow, and only a small-size spring with small elasticity can be selected, so that the feedback force is very small; 2.18 the rolling-in and rolling-out process of the steel ball in the two limit grooves is very short, while the structure of the steel ball between the two limit grooves is in rolling friction, and the resistance generated in the process is almost zero. Therefore, the damping sense and the suction sense which can only occur in the rolling-out process and the rolling-in process can lead the hand feeling fed back by the mechanism to be very abrupt and stiff; 3.18 in the process that the steel ball rolls into the spacing groove, the 18 steel ball strikes the bottom of the spacing groove under the action of 19 spring elastic forces, and quite obvious 'rattling' abnormal sound is generated.
In conclusion, the commonly adopted gear engaging, gear picking and hand feeling feedback mechanism with the spring, the steel ball and the steel ball limiting groove has the following defects: 1. the feedback force is too small; 2. the hand feeling is hard; 3. there is abnormal sound when engaging or disengaging gear.
Therefore, it is necessary to design a manual shift mechanism of a driving simulator to solve the above-mentioned problems in the background art.

Referring to fig. 1-7, the present invention provides a technical solution, which specifically comprises:
a manual gear shifting mechanism of a driving simulator comprises a gear lever 1 and a base 9, a gear shifting mechanism main body 2 is arranged below the gear lever 1, a knuckle bearing 3 is sleeved at the bottom of the gear lever 1, a spherical joint 4 is connected to one side of the knuckle bearing 3, a slider screw 5 is arranged on one side of the spherical joint 4 away from the gear lever 1, an elastic sheet 6 is arranged on an elastic sheet slide rail seat 7, an elastic sheet slide rail seat 7 is connected to the base 9, and a nylon slider 8 is connected to the slider screw 5, through redesigning the structure, a hand feeling feedback mechanism is independent of the whole manual gear shifting mechanism, a mode of combining the elastic sheet slide rail and the nylon slider 8 is adopted, the damping and suction hand feeling fed back by the manual gear shifting mechanism is improved during gear shifting and gear picking, the operation hand feeling of the manual gear shifting mechanism is more approximate to the hand feeling of a real vehicle, and the problem that the feedback force existing in the related technology is small at present can be solved, the hand feeling is hard and the gear is put on or taken off, and the gear has the defect of abnormal sound.
In the embodiment, referring to fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6 and fig. 7, a gear lever 1 is rotatably connected with a gear engaging mechanism main body 2 through a rotating shaft and can rotate around the rotating shaft at a certain angle, an inner ring of a joint bearing 3 is sleeved at the lower end of the gear lever 1, the bottom of the gear lever is fixed through an E-shaped snap spring, an external thread end of a spherical joint 4 is in threaded connection with an internal thread end of the joint bearing 3, a spring piece slideway seat 7 is fixedly connected with a base 9 through four screws, and the number of the spring pieces 6 is 8, wherein the upper 4 pieces are in threaded connection with the spring piece slideway seat 7, the lower 4 pieces are in threaded connection with the base 9, and a nylon sliding block 8 is locked on the sliding block screw rod 5 through two nuts, the damping and the suction hand feeling fed back by the manual gear shifting mechanism enable the operation hand feeling of the manual gear shifting mechanism to be closer to the real vehicle hand feeling, and can solve the defects of small feedback force, hard hand feeling and abnormal sound during gear engaging and gear disengaging in the prior art.
The working principle is as follows: when in use, as shown in fig. 2, in an initial state, the nylon sliding block 8 is located in the middle of the elastic sheet 6, and because the elastic sheets 6 around all the nylon sliding block 8 output pressure to the nylon sliding block, the nylon sliding block 8 is fixed in the position, and the stop lever 1 is located in a vertical position; as shown in fig. 5, when the shift lever 1 is pushed forward or backward, the shift lever 1 rotates around the rotation axis, the lower end of the shift lever drives the knuckle bearing 3 to swing, the knuckle bearing 3 drives the spherical joint 4 to move forward or backward, the spherical joint 4 drives the slider screw 5 and the nylon slider 8 to move in the spring slide, when the nylon slider 8 moves, the nylon slider 8 is squeezed by the upper and lower four springs 6, so the elastic force of the nylon slider 8 is much greater than the elastic force provided by a small spring in the prior art, at this time, the manual shift gear engaging mechanism feeds back a clear damping sense to the driver, when the nylon slider 8 continues to slide, one end surface of the nylon slider 8 crosses the peak of the spring 6, at this time, the elastic force of the spring 6 does not play a direct resistance role on the nylon slider 8, but applies a pressure perpendicular to the upper and lower surfaces of the nylon slider 8 to generate a friction force to continue to block the movement of the nylon slider 8, see FIG. 6; at this time, the manual gear engaging mechanism feeds back a smaller damping feeling to the driver than that of the previous stage. The small damping feeling combines the damping feeling and the suction feeling at two sides together, so that the gear engaging and gear disengaging hand feeling feedback of the manual gear engaging mechanism is smooth and mellow and is closer to the real vehicle hand feeling, when the nylon sliding block 8 slides to a certain position, the convex part in the middle of the elastic sheet 6 can be gradually embedded with the groove in the middle of the nylon sliding block 8, and the elastic force of the elastic sheet 6 generates thrust to the movement of the nylon sliding block 8 in the process and feeds back the suction feeling of the gear engaging to a driver, as shown in figure 7; the nylon sliding block 8 is made of non-metal materials, so that the nylon sliding block has a good impact absorption effect, and abnormal sound cannot be generated due to movement and friction between the nylon sliding block and the elastic sheet 6, and as can be seen from the above description, the utility model adopts a mode of combining the elastic sheet slide way and the nylon sliding block, so that three main problems of hand feeling feedback during gear shifting and gear picking in the prior art are improved: 1. the feedback force is too small; 2. the hand feeling is hard; 3. there is abnormal sound when engaging or disengaging gear. The hand feeling of the manual gear shifting mechanism is closer to the hand feeling of a real vehicle, and the hand-operated gear shifting mechanism has certain popularization value.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
