[0023] The present application provides a rail transit transfer guiding device, which will be described in detail below in conjunction with specific embodiments.

[0024] As shown in Figure 1 and Figure 2 , the rail transit transfer guiding device provided by the embodiments of the present application comprises a base 1, a mechanical arm 2, a display screen 3 and a cleaning assembly 4; the base 1 is provided with a mounting cavity 11 with an opening 1121 facing upward; the mechanical arm 2 is arranged at the upper end of the base 1; the display screen 3 is connected to the free end of the mechanical arm 2; the cleaning assembly 4 is movably arranged in the mounting cavity 11, and after the mechanical arm 2 drives the display screen 3 to cover the opening 1121 of the mounting cavity 11, the cleaning assembly 4 is used to move in a direction parallel to the opening 1121 of the mounting cavity 11 to clean the display screen 3.

[0025] Specifically, the upper wall of the installation cavity 11 can be provided with an opening to form an opening 1121. The direction parallel to the opening 1121 of the installation cavity 11 refers to the direction parallel to the plane where the upper edge of the opening 1121 is located. In addition, the mechanical arm 2 can include at least two rotating arms and an angle adjustment assembly, the two rotating arms can rotate relative to each other to drive the display screen 3 to move to adjust the height of the display screen 3, and can drive the display screen 3 to be folded down to the opening 1121 of the installation cavity 11 (the unfolded state can be referred to Figure 1 , and the folded state can be referred to Figure 2 ). Specifically, the display screen 3 has a front surface and a back surface, the back surface of the display screen 3 is connected to the mechanical arm 2, and the front surface of the display screen 3 is away from the mechanical arm 2 for display; when the display screen 3 is folded to the opening 1121 of the installation cavity 11, the front surface of the display screen 3 for display faces the installation cavity 11, and the back surface of the display screen 3 is away from the installation cavity 11.

[0026] In this embodiment, since the display screen 3 is connected to the free end of the mechanical arm 2, the mechanical arm 2 can drive the display screen 3 to move by adjusting itself, so as to change the height of the display screen 3 to adapt to the visibility requirements of passengers of different heights, thereby improving the use experience of passengers; at the same time, since the cleaning assembly 4 is movably arranged in the installation cavity 11, after the mechanical arm 2 drives the display screen 3 to be folded to the opening 1121 of the installation cavity 11, the cleaning assembly 4 can reciprocate in the direction parallel to the opening 1121 of the installation cavity 11 to wipe the front surface of the display screen 3 facing the installation cavity 11, so as to clean the display screen 3, thereby ensuring the cleanliness of the display screen 3, making it more convenient for passengers to watch, and further improving the use experience of passengers.

[0027] Optionally, as shown in Figure 3 , the cleaning assembly 4 includes a moving seat 41, a spring 42 and a wiping member 43, the spring 42 is arranged at the upper end of the moving seat 41, and the wiping member 43 is arranged at the upper end of the spring 42, and the top surface of the wiping member 43 is used to contact the front surface of the display screen 3.

[0028] Specifically, the lower end of the moving seat 41 can be provided with a supporting wheel 411, and the supporting wheel 411 is placed on the bottom wall surface of the installation cavity 11, so that the supporting wheel 411 rolls along the bottom wall surface of the installation cavity 11 to drive the entire cleaning assembly 4 to move.

[0029] In the optional embodiment, when the display screen 3 needs to be cleaned, the top surface of the wiping member 43 is in contact with the front surface of the display screen 3, so that the wiping member 43 can reciprocate along the front surface of the display screen 3 with the movement of the moving seat 41, thereby achieving wiping of the display screen 3; meanwhile, since the wiping member 43 and the moving seat 41 are connected through the spring 42, the spring force generated by the spring 42 can ensure that the top surface of the wiping member 43 is in close contact with the front surface of the display screen 3, so that the wiping effect is improved and the cleaning effect is better.

[0030] Optionally, as shown in Figure 1 and Figure 3 , the rail transit transfer guiding device further comprises a driving push rod 5 installed in the mounting cavity 11, the driving push rod 5 is arranged in a direction parallel to the opening 1121 of the mounting cavity 11, and the output end of the driving push rod 5 is connected with the moving seat 41.

[0031] It should be noted that the specific implementation of the driving push rod 5 is not limited, for example, a pneumatic cylinder or a linear motor can be used.

[0032] In the optional embodiment, since the driving push rod 5 is arranged in a direction parallel to the opening 1121 of the mounting cavity 11, and the output end of the driving push rod 5 is connected with the moving seat 41, when the driving push rod 5 is extended or retracted, the driving push rod 5 can drive the moving seat 41 to move in a direction parallel to the opening 1121 of the mounting cavity 11, thereby driving the entire cleaning assembly 4 to move in a direction parallel to the opening 1121 of the mounting cavity 11, thereby achieving cleaning of the display screen 3.

[0033] Optionally, as shown in Figure 1 and Figure 3 , the mounting cavity 11 comprises a first cavity 111 and a second cavity 112 connected in communication, the first cavity 111 and the second cavity 112 are arranged in sequence horizontally, the driving push rod 5 is arranged in the first cavity 111, and the top wall of the second cavity 112 forms the opening 1121 of the mounting cavity 11; after the display screen 3 is covered on the opening 1121 of the mounting cavity 11, the driving push rod 5 drives the moving seat 41 to move from the first cavity 111 to the second cavity 112, so that the top surface of the wiping member 43 is in contact with the front surface of the display screen 3.

[0034] In the alternative embodiment, since the driving push rod 5 is arranged in the first cavity 111, and the top wall of the second cavity 112 forms the opening 1121 of the mounting cavity 11, the driving push rod 5 will only be extended to drive the moving seat 41 to move from the first cavity 111 to the second cavity 112 after the display screen 3 is covered on the opening 1121 of the mounting cavity 11, so that the top surface of the wiping member 43 is in contact with the front surface of the display screen 3 to clean the display screen 3. That is, when the display screen 3 does not need to be cleaned, the driving push rod 5 and the cleaning assembly 4 are in the first cavity 111, and the upper wall of the first cavity 111 can shield the driving push rod 5 and the cleaning assembly 4 to avoid exposing the driving push rod 5 and the cleaning assembly 4, thereby improving the aesthetic appearance.

[0035] Further, the profile size of the display screen 3 can be matched with the profile size of the opening 1121, and when the display screen 3 is covered on the opening 1121 of the mounting cavity 11, the display screen 3 is inserted into the opening 1121, and the front surface of the display screen 3 is flush with the top wall of the first cavity 111. In this way, the front surface of the display screen 3 and the top wall of the first cavity 111 can be in the same plane, which is more convenient for the wiping member 43 to wipe the front surface of the display screen 3.

[0036] Optionally, as shown in Figure 3 the upper end of the moving seat 41 is provided with a vertically arranged guide sleeve 44, and the lower end of the wiping member 43 is provided with a guide rod 45 which is guided and matched with the guide sleeve 44.

[0037] Specifically, the guide sleeve 44 and the guide rod 45 can be provided with two groups and are arranged on both sides of the spring 42.

[0038] In the alternative embodiment, since the guide sleeve 44 is vertically arranged, and the guide rod 45 is guided and matched with the guide sleeve 44, the guide rod 45 will only slide up and down along the guide sleeve 44, and will not be radially deflected relative to the guide sleeve 44, thereby effectively preventing the wiping member 43 from being deflected to ensure that the top surface of the wiping member 43 is fully attached to the front surface of the display screen 3, thereby facilitating the improvement of the cleaning effect.

[0039] Optionally, as shown in Figure 3 the wiping member 43 includes a connecting plate 431 connected with the spring 42 and a wiping cotton 432 arranged at the upper end of the connecting plate 431.

[0040] Specifically, the wiping cotton 432 can be bonded with the connecting plate 431.

[0041] In the optional embodiment, the wiping cotton 432 is soft, which is convenient for wiping the display screen 3 and does not damage the surface of the display screen 3. Meanwhile, the wiping cotton 432 is soft, which is not convenient for being connected with the spring 42. Therefore, the connecting plate 431 is designed at the lower end of the wiping cotton 432, the connecting plate 431 is hard, which is convenient for being connected with the spring 42 and can ensure the firmness of the connection, thereby helping to improve the use reliability of the cleaning assembly 4.

[0042] Optionally, as shown in Figure 1 and Figure 2 , the mechanical arm 2 comprises a connecting seat 21, a first rotating arm 22, a second rotating arm 23 and an angle adjusting assembly 24. The connecting seat 21 is arranged on the base 1. One end of the first rotating arm 22 is rotationally connected with the connecting seat 21, and the other end is rotationally connected with the second rotating arm 23. The angle adjusting assembly 24 is arranged on the second rotating arm 23. The display screen 3 is connected with the angle adjusting assembly 24. The angle adjusting assembly 24 is used for adjusting the included angle of the display screen 3 relative to the central axis of the second rotating arm 23.

[0043] In the optional embodiment, the two ends of the first rotating arm 22 are respectively rotationally connected with the connecting seat 21 and the second rotating arm 23, which can make the mechanical arm 2 form a multi-degree-of-freedom mechanical arm structure. The first rotating arm 22 is rotated relative to the connecting seat 21 and / or the second rotating arm 23 is rotated relative to the first rotating arm 22, that is, the posture of the whole mechanical arm 2 is adjusted, so that the height of the display screen 3 can be changed to adapt to the visibility requirements of passengers of different heights. Meanwhile, the angle adjusting assembly 24 is arranged on the second rotating arm 23. The angle adjusting assembly 24 can adjust the included angle of the display screen 3 relative to the central axis of the second rotating arm 23. In this way, after the height of the display screen 3 is changed by the action of the two rotating arms, the angle of the display screen 3 can be immediately adjusted by the angle adjusting assembly 24 to face the passenger, so as to ensure that the passenger can normally watch.

[0044] Optionally, as shown in Figure 4 , the angle adjusting assembly 24 comprises a mounting plate 241 and two electric telescopic rods 242. The mounting plate 241 is arranged at the free end of the mechanical arm 2. One end of each of the two electric telescopic rods 242 is hingedly connected to the opposite ends of the mounting plate 241. The other end of each of the two electric telescopic rods 242 is hingedly connected to the back of the display screen 3.

[0045] Specifically, referring to Figure 4, the display screen 3 is in a vertical state driven by the mechanical arm 2, at this time, the mounting plate 241 is also in a vertical state, one end of one of the two electric telescopic rods 242 is hinged to the upper end of the mounting plate 241, the other end is hinged to the upper part of the back of the display screen 3, one end of the other electric telescopic rod 242 is hinged to the lower end of the mounting plate 241, and the other end is hinged to the lower part of the back of the display screen 3. It can be understood that, based on the state shown in Figure 4 , when the upper electric telescopic rod 242 is shortened and the lower electric telescopic rod 242 is lengthened, the front of the display screen 3 will change to be inclined upward; when the upper electric telescopic rod 242 is lengthened and the lower electric telescopic rod 242 is shortened, the front of the display screen 3 will change to be inclined downward.

[0046] In this alternative embodiment, since the mounting plate 241 and the display screen 3 are connected by two electric telescopic rods 242, when the two electric telescopic rods 242 are lengthened or shortened, the angle of the display screen 3 will change, thereby changing the included angle of the display screen 3 relative to the central axis of the second rotating arm 23, and ensuring that the front of the display screen 3 faces the passenger.

[0047] Alternatively, as shown in Figure 4 , the mounting plate 241 is provided with a connecting sleeve 243 on the end face facing the display screen 3, the connecting sleeve 243 is provided with a spherical groove, and the back of the display screen 3 is provided with a spherical connector 31 matched with the spherical groove.

[0048] In this alternative embodiment, through the connecting sleeve 243 and the spherical connector 31, when the display screen 3 is rotated to any angle by the angle adjusting assembly 24, the spherical connector 31 is always matched with the spherical groove of the connecting sleeve 243, so that the mounting plate 241 can always support the display screen 3 through the connecting sleeve 243 and the spherical connector 31, thereby preventing the display screen 3 from shaking and improving the user experience.

[0049] Alternatively, as shown in Figure 4 , the rail transit transfer guiding device further comprises a camera 6 and a control module, the camera 6 is arranged on the display screen 3, and the control module is electrically connected with the camera 6 and the mechanical arm 2 respectively.

[0050] Specifically, the camera 6 can be arranged in a spaced manner with the circumferential surface of the display screen 3, so as to avoid interference between the camera 6 and the base 1 when the display screen 3 is covered on the opening 1121 of the mounting cavity 11.

[0051] In the optional embodiment, the camera 6 can be used to capture the height information of the passenger through the camera 6 and the control module, and the control module can be used to control the mechanical arm 2 to act to adjust the height of the display screen 3 according to the height information, so as to realize automatic adjustment of the height of the display screen 3 according to the passenger to be watched, and further improve the use experience.

[0052] Although the present application is disclosed as above, the protection scope of the present application is not limited to this. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application, and these changes and modifications will fall within the protection scope of the present application.
