Description

Technical Field

[0001] The invention belongs to the technical field of unmanned special vehicle control systems, and in particular relates to a vehicle-mounted keyboard flipping device. Background Art

[0002] At present, my country's unmanned special vehicles are still in a rapid development stage. Controlling unmanned special vehicles requires operating the on-board remote computer. The on-board keyboard, as the input device of the remote computer, will cause the unmanned special vehicle to lose control once damaged, and it plays an indispensable role. Because there are many devices in the control cabin, the activity space between the personnel and the keyboard becomes particularly narrow. During the transportation of the control cabin, due to the undulating road surface, the operator swings back and forth in the control cabin, which is easy to collide with the on-board keyboard, increasing the probability of injury to the operator. Therefore, it becomes very necessary to release more activity space. Summary of the invention

[0003] 1. Technical issues to be resolved

[0004] The present invention proposes a vehicle-mounted keyboard flipping device to solve the technical problem of how to achieve a reasonable layout of the activity space between the keyboard and the operator through an integrated structural design, improve the internal space utilization rate of the control cabin, release space, and avoid collision between the keyboard and the operator while the vehicle is driving.

[0028] The keyboard platen 7 is formed by Z-shaped bending, and the bottom surface and side edges of the keyboard 12 are fixedly connected to the six keyboard platens 7. The keyboard bracket 10 is fixedly connected to each keyboard platen 7 by a plurality of fixing bolts 11, and the side edges of the keyboard 12 are bonded to the inner surface of the keyboard bracket 10, so that the keyboard 12 is clamped between the keyboard bracket 10 and the keyboard platen 7. The keyboard platen 7 and the keyboard bracket 10 can be adjusted according to the external dimensions of the keyboard 12.

[0029] Two pins 8 are welded on the left side of the keyboard bracket 10, one pin 8 is used as a rotating pin, and the other pin 8 is used as a sliding pin. A pin 8 is welded on the right side of the keyboard bracket 10 as a rotating pin, and a lock body mounting hole is processed on the side of the right pin 8. The left and right rotating pins are coaxially arranged, and the left sliding pin is coaxially arranged with the lock body mounting hole. The lock body 4 is welded on the inner side of the lock body mounting hole, and a step hole is processed through the center of the lock body 4.

[0030] The bottom plates of the right L-shaped plate 3 and the left L-shaped plate 9 are provided with mounting holes (one or more in number), and the right L-shaped plate 3 and the left L-shaped plate 9 are respectively fixed to the seats or interior panels in the vehicle using bolts through the mounting holes to ensure the stability of the keyboard structure during the flipping process. The side plates of the right L-shaped plate 3 and the left L-shaped plate 9 are respectively provided with rotation pin limit holes and sliding holes, and the left and right rotation pin limit holes are respectively used to insert the left and right rotation pins of the keyboard bracket 10, and the keyboard 12 can rotate around the two rotation pins with the keyboard bracket 10.

[0031] The sliding hole of the left L-shaped plate 9 is used to insert the left sliding pin of the keyboard bracket 10. When the keyboard 12 rotates around the rotating pin, the left sliding pin slides in the sliding hole of the left L-shaped plate 9. The sliding hole of the right L-shaped plate 3 is used to insert the locking pin 2, and locking pin limiting holes are processed at both ends of the sliding hole. When the locking pin 2 is fully inserted into the step hole of the lock body 4, the limiting cylindrical surface on the locking pin 2 cooperates with the locking pin limiting holes to limit the locking pin 2 at one of the locking pin limiting holes, thereby fixing the keyboard 12 at the current rotation end position; when the locking pin 2 is pulled out of the step hole of the lock body 4, the limiting cylindrical surface of the locking pin 2 is disengaged from the locking pin limiting hole, and when the keyboard 12 rotates around the rotating pin, the locking pin 2 can slide in the sliding hole.

Figure 4As shown. The locking pin 2 is provided with a limiting cylindrical surface that matches the locking pin limiting hole. When the key ring 1 is pulled, the locking pin 2 and the nut 6 are driven to tighten the compression spring 5. At this time, the limiting cylindrical surface of the locking pin 2 and the locking pin limiting hole are disengaged from the limiting position, and the keyboard 12 can be rotated to a suitable position to realize the conversion of the keyboard 12 between the storage posture and the open posture. The locking pin 2 slides to the locking pin limiting hole corresponding to the position as the keyboard 12 is rotated. After releasing the key ring 1, the limiting cylindrical surface of the locking pin 2 and the locking pin limiting hole are limited to fix the keyboard 12 in the rotation end posture position, as shown in FIG. Figure 5 and 6 As shown in the figure, it can be seen that the keyboard 12 can release more space for activities after being turned over and stored.
