Technical Field

[0001] This application relates to the field of rail vehicle technology, and more specifically, to a high-efficiency power transmission device for automatic opening and closing of the head cover of a rail train driver's cab. Background Technology

[0002] The driver's cab hood is the covering structure at the front of the driver's cab of a rail vehicle. It usually includes windows and lighting equipment. When performing maintenance on the devices inside the driver's cab hood, the hood needs to be removed.

[0003] In related technologies, to address the problem that driver's cab hoods are fixed to the vehicle body with bolts and connecting brackets, making disassembly and maintenance inconvenient, a patent with publication number CN215204860U provides a mechanism for opening and closing a driver's cab hood for rail vehicles. This device uses a drive mechanism to rotate four drive shafts, which in turn rotate four upper and four lower connecting rods. Through the principle of a parallelogram linkage mechanism, it can drive the two opening and closing hood baffles to merge and separate, thus opening and closing the hood. This facilitates the inspection and maintenance of the equipment inside the train driver's cab hood. The structure is simple, the operation is stable and reliable, the response speed is fast, and the space occupation is small.

[0004] Although the existing technical solutions mentioned above can facilitate the opening and closing of the headgear by setting a drive structure to drive the opening and closing of the face shield baffle, according to the inspection and operation requirements of the rail train, after the face shield baffle is opened, it is necessary to inspect the various mechanical parts inside the headgear, and to clean the oil stains on the opening and closing mechanism, the worn parts of each mechanical part, and the connecting rod shaft. The connection gap of the multi-link mechanism is small, which makes it inconvenient to clean the oil stains and increases the difficulty of maintenance.

Detailed Implementation

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 This application discloses an efficient power transmission device for automatic opening and closing of a train driver's cab head cover, including a support plate 1, which is fixedly installed inside the head cover of the train driver's cab. Vertical shafts 2 are rotatably installed on both sides of the support plate 1, and the two vertical shafts 2 are respectively fixedly installed with corresponding opening and closing baffles 100. The two opening and closing baffles 100 are installed inside the cover 200 and each includes a front baffle 1001 and a side baffle 1002. The vertical shafts 2 are fixedly installed inside the side baffles 1002. A drive shaft 3 is rotatably installed on the top of the support plate 1, and the two ends of the drive shaft 3 are respectively linked with the corresponding vertical shafts 2. The drive shaft 3 is driven to rotate a certain angle by an external force. A sliding plate A4 is slidably installed on the top of the support plate 1, and a locking component 41 is installed at the end of the sliding plate A4. After the drive shaft 3 rotates a certain angle, the sliding plate A4 drives the locking component 41 to slide, which is used to automatically lock the opening and closing baffles 100 and the support plate 1.

[0030] When the opening and closing baffle 100 opens and closes, the drive shaft 3 is driven to rotate by an external force to rotate a certain angle, so that the drive shaft 3 is linked with the vertical shaft 2, which drives the two vertical shafts 2 to rotate a certain angle, thereby driving the two opening and closing baffles 100 to open and close, thus completing the effect of opening and closing the equipment. By replacing the connecting rod in the prior art with the two vertical shafts 2, the opening and closing baffle 100 can complete the automatic opening and closing, so that there is no need to clean the oil stains at the rotating shaft of the connecting rod during maintenance, thereby simplifying the maintenance steps and reducing the maintenance difficulty.

[0031] After the drive shaft 3 rotates to a certain angle, the slide plate A4 drives the locking component 41 to slide under the external force, so that the locking component 41 automatically locks the opening and closing baffle 100 and the support plate 1, preventing excessive vibration and friction between the opening and closing baffle 100 and the support plate 1 during the driving process.

[0032] Reference Figure 2 , Figure 3 and Figure 4 A worm gear 21 is fixedly installed at the bottom of the vertical shaft 2, and worms 31 are fixedly installed at both ends of the drive shaft 3. The worm gear 21 meshes with the worm 31 for transmission. A gear 32 is fixedly installed on the outer side of the drive shaft 3 between the two worms 31. An electric push rod 5 is installed on the side of the bearing plate 1 away from the engagement baffle 100. The electric push rod 5 is used to drive the toothed plate 54 to move. The bottom of the toothed plate 54 meshes with the outer side of the gear 32. A sliding plate B51 is fixedly installed at the output end of the electric push rod 5. The sliding plate B51 is slidably mounted on the slide. On the outer side of the moving shaft 52, a limiting plate A521 is fixedly installed on the side of the sliding shaft 52 away from the gear 32. A spring 53 is sleeved on the outer side of the sliding shaft 52 away from the limiting plate A521. The other side of the sliding shaft 52 is fixedly installed with the toothed plate 54. The bottom of the toothed plate 54 is engaged with the outer side of the gear 32. The electric push rod 5 is fixedly installed inside the head cover of the railcar driver's cab through a fixed seat 57. A slide rail A58 is fixedly installed on the top of the fixed seat 57. The bottom of the slide rail A58 is slidably installed with the toothed plate 54.

[0033] The electric push rod 5 drives the slide plate B51 to move, causing it to slide outside the sliding shaft 52. This pushes the spring 53, compressing it. The toothed plate 54 moves under the elastic push of the spring 53, which in turn drives the gear 32 to rotate. The gear 32 then drives the drive shaft 3 to rotate, which in turn drives the two worm gears 31 to rotate. The two worm gears 31 mesh with the two worm wheels 21, causing the two worm wheels 21 to rotate the two vertical shafts 2 by a certain angle. This, in turn, causes the two opening and closing baffles 100 to rotate and open. When the two opening and closing baffles 100 need to be closed, the electric push rod 5 simply drives the slide plate B51 to move in the opposite direction, causing the two vertical shafts 2 to rotate in the opposite direction and closing the two opening and closing baffles 100.

[0034] Reference Figure 3 , Figure 4 and Figure 5 The fixed base 57 and the support plate 1 are jointly fixedly provided with a slide rail B59. The slide plate A4 is slidably provided on the top of the corresponding slide rail B59. The bottom of the toothed plate 54 is fixedly provided with a limit plate B55. The outer side of the toothed plate 54 is fixedly provided with a distance sensor 56. The locking assembly 41 includes a magnet 411. The magnet 411 is fixedly provided on the top of the corresponding slide plate A4. The bottom of the slide plate A4 is attracted to a slider 412 by the magnet 411. The bottom of the opening and closing baffle 100 is provided with a sliding opening A1003 corresponding to the slider 412. The top of the support plate 1 is provided with a sliding opening B11 corresponding to the slider 412.

[0035] After the opening and closing baffle 100 is opened, the electric push rod 5 continues to push the slide plate B51, causing the two slide plates A4 to slide on the top of the slide rail B59. This drives the two locking components 41 to move to the top of the sliding opening A1003 and the sliding opening B11. Under the attraction of the magnet 411, the slider 412 slides upward inside the sliding opening B11 and the sliding opening A1003, so that the sliding opening A1003 locks the opening and closing baffle 100 and the bearing plate 1, preventing the opening and closing baffle 100 from shaking when the train is running, and avoiding wear on the self-locking position between the worm gear 21 and the worm 31. The distance sensor 56 detects the distance to the slide plate B51, which can infer the sliding position of the locking component 41, thereby determining the locking status of the locking component.

[0036] In summary, the high-efficiency power transmission device for automatic opening and closing of the train driver's cab headgear disclosed in this application, when in use, moves the sliding plate B51 via the electric push rod 5, causing the sliding plate B51 to slide outside the sliding shaft 52. This causes the sliding plate B51 to push the spring 53, compressing the spring 53. The toothed plate 54 moves under the elastic push of the spring 53, thereby driving the gear 32 to rotate. The gear 32 then drives the drive shaft 3 to rotate, which in turn drives the two worm gears 31 to rotate. The two worm gears 31 mesh with the two worm wheels 21, causing the two... The worm gear 21 drives the two vertical shafts 2 to rotate at a certain angle, thereby causing the two opening and closing baffles 100 to rotate and open. When the two opening and closing baffles 100 need to be closed, the electric push rod 5 drives the slide plate B51 to move in the opposite direction, which causes the two vertical shafts 2 to rotate in the opposite direction, thereby causing the two opening and closing baffles 100 to close. By replacing the connecting rod in the prior art with the two vertical shafts 2, the opening and closing baffles 100 can be opened and closed automatically. This eliminates the need to clean the oil stains at the shaft of the connecting rod during maintenance, thereby simplifying the maintenance steps and reducing the maintenance difficulty.
