Further, the gas spring 24 of the present embodiment can provide a compression damping function when compressed and a tension boosting function when extended. When the display mounting bracket 40 is switched to the open position, the gas spring 24 compresses, and the opening process of the display mounting bracket 40 is slow, so that the impact on a person during opening is avoided; while closing, the closing speed can be increased by the restoring force of the gas spring 24 when the compression is released. Thereby, safe opening and easy closing of the display mount 40 can be achieved.

Referring to fig. 1 and 3, the second opening/closing mechanism of the present application includes a supporting shaft 31, a mounting base 32, and a limiting member 33, the supporting shaft 31 is connected to the movable end of the first opening/closing mechanism, the mounting base 32 is disposed on the supporting shaft 31, the limiting member 33 is connected to the mounting base 32, the display mounting bracket 40 is rotatably connected to the supporting shaft 31 (the display mounting bracket 40 of the present embodiment is disposed on the supporting shaft 31 through a nylon bearing), and the limiting member 33 is used for limiting the display mounting bracket 40, so that the display mounting bracket 40 can be switched from an open position to a maintenance position, or switched from the maintenance position to the open position.

Further, the display mounting bracket 40 includes a plurality of limiting points 41, and the limiting members 33 and/or the limiting points 41 are plural, and the limiting members 33 can be matched with the limiting points 41. The limit point 41 of the present embodiment is provided with a limit hole. As shown in fig. 3, the limiting member 33 is a reference spring pin, and a core shaft of the reference spring pin can be inserted into the limiting hole.

A plurality of indexing spring pins can be arranged, one indexing spring pin can also be arranged, when one indexing spring pin is arranged, a plurality of limiting holes are arranged, and the display mounting frame 40 can have different angles relative to the supporting shaft 31 through matching with the limiting holes at different positions; when a plurality of the limiting holes are arranged, one limiting hole can be arranged, and the display mounting frame 40 can have different angles relative to the supporting shaft 31 by matching the limiting holes with the indexing spring pins at different positions; when the quantity of indexing spring pin and spacing hole all is a plurality of, can be through the matching of different indexing spring pins and different spacing holes, can make angle modulation more meticulous, promptly, can big angle modulation, also can the small angle modulation, the adjustment precision is higher. According to the actual maintenance requirement, the indexing spring pins and the limiting holes in corresponding quantity can be arranged.

In the present embodiment, the number of the indexing spring pins is three, and the three indexing spring pins are spaced apart along the circumferential direction of the mounting seat 32. The limiting holes are provided with two, and different angles can be limited by combining with different indexing spring pins. Optionally, each limiting hole is provided with a nylon bearing, so that abrasion between the indexing spring pin and the wall of the limiting hole is reduced.

Alternatively, when the position-limiting member 33 is different, the position-limiting point 41 may have other variations, and is not limited to using only the cooperation of the index spring pin and the position-limiting hole.

Based on the above-described mounting mechanism 100 for the passenger information display, the present application provides a display system including a display device and the mounting mechanism 100 for the passenger information display, the display device being provided to the display mounting bracket 40.

The principle of the embodiment is as follows:

the structure of the embodiment is simple, the support arm 22, the rotating shaft 21, the gas spring 24, the display mounting frame 40 and the indexing spring pin can be pre-assembled to form a pre-assembly when being mounted, then the pull rod 233 is connected with the toggle switch 2311 of the snap lock, the snap lock is mounted between the fixing frames 10 on two sides, and then the pre-assembly is assembled between the fixing frames 10 on two sides to complete the assembly without more parts.

In the closed position, the entire display device and the mounting mechanism 100 of the passenger information display can be folded, so that it does not always take up more space to maintain the posture, and only needs to be switched to the open position when it needs to be opened, and the space occupancy rate is lower compared with that of a general suspension type display.

When the display device is opened, the locking of the lock pin by the snap lock can be released only by pulling the pull rod 233, and the display device can be slowly and safely opened under the action of gravity and the buffering action of the gas spring 24. It should be noted that opening does not mean to activate the display device, but means to separate the display device from the top of the vehicle cabin by a certain distance, so that an operator can view the back of the display device and repair or disassemble the display device according to the situation.

If the lock is to be closed, the display mounting frame 40 can be pushed, so that the lock pin can be pushed to move upwards, and of course, when the air spring 24 plays a certain boosting role, the whole ascending process is not too fast, so that the equipment is prevented from being damaged, and when the lock pin is locked by the lock tongue 2312 of the buckle lock, the display equipment is locked.

When the display device needs to be overhauled, three indexing spring pins at two ends of the supporting shaft 31 can be pulled outwards respectively under the condition that the display device is opened, and the indexing spring pins can be rotated by 30 degrees, so that the indexing spring pins can be kept in an unlimited state. At this moment, can rotate display mounting bracket 40 to the angle that is fit for overhauing, continue to rotate indexing spring pin 30 again, then can realize the fixed of the position of display equipment to convenient maintenance. Of course, in the operation of "continuously rotating the index spring pins by 30 °, only one of the index spring pins may be switched, and the posture of the display mount 40 may be maintained. During the maintenance process, by repeating the above switching process, the display mount 40 can have different angular positions (posture changes as shown in fig. 5 to 7) so as to facilitate the personnel to check the situation and perform maintenance operation.

Therefore, the whole process does not need to disassemble the whole display equipment, and the display equipment can be adjusted from the closed position to the open position or the maintenance position when in the working state. Namely, the condition of the display device can be conveniently checked by an operator on line without powering off the display device; when further maintenance is required, the power supply of the display device can be disconnected according to actual requirements. If necessary, the display device can be conveniently taken down, and the display device after being maintained or a new display device can be conveniently installed on the display installation frame 40, so that the maintenance work is more flexible.

After the maintenance is finished, the indexing spring pins are operated reversely, the display mounting frame 40 is rotated to the opening position, then the display mounting frame 40 is pushed upwards and reversely until the buckle lock generates ' clicking ', and the locking is achieved after the click ' is generated.

To sum up, the installation mechanism 100 of the passenger information display of the present application can make the display installation frame 40 have more position changes by designing the first opening and closing mechanism and the second opening and closing mechanism, so that the operator can install, detach and overhaul the display device more conveniently, and the display system using the installation mechanism can also be more convenient to overhaul and maintain in daily use.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
