Technical Field

[0001] The utility model relates to a display device, in particular to a high-resolution display device for displaying dynamic maps. Background Art

[0002] With the rapid development of urban rail transit, the subway has become the first choice for people to travel conveniently. On the subway, people pay attention to information such as their destination arrival time and location. In the past, they could only rely on broadcast announcements, simple flashing indicator lights, and LED scrolling information on door frames. Now, we have integrated these simple elements into LCD as an information prompt carrier, displaying color pages to let passengers intuitively know the required dynamic subway map.

[0003] Typically, LCD screens are installed at a relatively high position in subway cars, and are often connected to an outer cover frame. If the LCD screen is damaged or requires repair, the outer cover frame, which is connected to the inner wall of the car, must be removed before the LCD screen can be repaired and inspected, which to a certain extent affects the normal use time of the subway car. In view of this, we propose a high-resolution display device for displaying dynamic maps. Utility Model Content

At the same time, the baffle set on the inner wall of the soft pad can block the upper end of the inner screen and the upper end of the side wall, without affecting the viewing experience and reducing the reflection during viewing.

[0006] Therefore, the utility model provides a high-resolution display device for displaying dynamic maps, which includes a display screen body, which is formed by splicing an outer panel and an inner panel. The surface of the display screen body is sleeved with a shell assembly for assisting the installation of the display screen body. The inner wall of one side of the shell assembly is connected to a reinforcement assembly, and the other end of the reinforcement assembly is located on the surface of the outer panel.

[0007] As a further improvement of the present technical solution, the shell assembly includes an outer shell that is sleeved on the surface of the display screen body, a middle pad is fixedly connected to the interior of the outer shell, the surface of the display screen body is in contact with the surface of the middle pad, a circuit storage compartment for storing circuits is provided inside the outer shell, mounting parts are fixedly connected on both sides of the outer shell, and a soft pad is fixedly connected to one end of the outer shell near the opening.

[0008] As a further improvement of the present technical solution, the reinforcement assembly includes a plurality of clips fixedly connected to the inner wall of the soft pad, and the surface of the outer plate is provided with a plurality of clip grooves that fit with the surface of the clips.

[0024] LCD screens are usually installed at relatively high places in subway cars, and are often connected to outer covers. If the LCD screen is damaged or needs repair, the outer cover connected to the inner wall of the car must be removed before the LCD screen can be repaired and inspected, which affects the normal use time of the subway car to a certain extent.

[0025] See also Figure 1-Figure 4 As shown, the device includes a display screen body 1, which is formed by splicing an outer panel 11 and an inner screen 12. The surface of the display screen body 1 is covered with a shell assembly 2 for assisting the installation of the display screen body 1. The inner wall of one side of the shell assembly 2 is connected to a reinforcement assembly 3, and the other end of the reinforcement assembly 3 is located on the surface of the outer panel 11, wherein the inner screen 12 is a 43-inch four-K strip screen.

[0026] First, the specific structure of the shell assembly 2 is disclosed. The shell assembly 2 includes an outer shell 21 that is sleeved on the surface of the display screen body 1. A middle pad 24 is fixedly connected to the interior of the outer shell 21. The surface of the display screen body 1 is in contact with the surface of the middle pad 24. A circuit storage compartment 25 for storing circuits is provided inside the outer shell 21. Mounting members 23 are fixedly connected to both sides of the outer shell 21. A soft pad 22 is fixedly connected to one end of the outer shell 21 near the opening. The middle pad 24 provided in the middle of the outer shell 21 allows the display screen body 1 to be mounted in contact with the surface of the middle pad 24 inside the outer shell 21. The circuit storage compartment 25 provided in the outer shell 21 facilitates the placement and connection of the circuits of the display screen body 1. The soft pad 22 provided at the end of the outer shell 21 allows the surface of the display screen body 1 to be wrapped and installed. When maintenance is required, the soft pad 22 can be pulled out to remove the display screen body 1 for maintenance, effectively improving the convenience of maintenance.

[0027] Next, the specific structure of the reinforcement assembly 3 is disclosed. The reinforcement assembly 3 includes several clips 31 fixedly connected to the inner wall of the soft pad 22. The outer panel 11 has a plurality of clip grooves 32 on its surface that mate with the clips 31. When the soft pad 22 is wrapped around the surface of the display screen body 1, the clips 31 fixedly connected to the inner wall of the soft pad 22 engage in the clip grooves 32 on the outer panel 11, further improving the connection between the soft pad 22 and the surface of the display screen body 1.

[0028] The improvement of this embodiment is that: first, the middle pad 24 arranged in the middle of the outer shell 21 is used, so that the display screen body 1 can be fitted on the surface of the middle pad 24 and installed inside the outer shell 21, and the line storage compartment 25 opened inside the outer shell 21 is used to facilitate the placement and connection of the lines of the display screen body 1. The surface of the display screen body 1 can be wrapped and installed by the soft pad 22 set at the end of the outer shell 21. When maintenance is needed, the soft pad 22 can be pulled around to take out the display screen body 1 for maintenance, which effectively improves the convenience of maintenance. When the soft pad 22 is wrapped around the surface of the display screen body 1, it drives several clips 31 fixedly connected to the inner wall of the soft pad 22 to be clamped in the clip groove 32 opened on the surface of the outer plate 11, further improving the connectivity between the soft pad 22 and the surface of the display screen body 1.

[0029] Since the display screen body 1 is installed at a relatively high place and the interior of the subway car is well-lit, considering the reflection of the display screen body 1 when viewing, in order to reduce the reflection problem of the display screen body 1 when viewing, the display screen body 1 is installed at a relatively high place and the interior of the subway car is well-lit. Figure 1-Figure 3 As shown, a baffle 4 is fixedly connected to the inner wall of the soft pad 22 close to the inner screen 12, and the baffle 4 is made of elastic material.

[0030] The improvement lies in that: by using the baffle 4 set on the inner wall of the soft pad 22, the upper end of the inner screen 12 and the upper end of the side wall can be blocked, which does not affect the viewing and reduces the reflection during viewing. The baffle 4 is made of elastic material and does not affect the shrinkage of the soft pad 22.

[0031] Considering the stability of the soft pad 22 on the display screen body 1, in order to further improve the clamping effect of the soft pad 22 on the display screen body 1, Figure 3-Figure 4 As shown, the inner wall of the clamping groove 32 and the end of the clamping piece 31 are both paved with magnetic gaskets 5.

[0032] The improvement lies in: by using the magnetic gasket 5 set on the inner wall of the clamping groove 32 and the end of the clip 31, when the clip 31 is clamped in the clamping groove 32, the stability of the connection between the clip 31 and the clamping groove 32 can be improved, thereby improving the clamping effect of the soft pad 22 on the display screen body 1.

[0033] In summary, the working principle of this solution is as follows: first, the middle pad 24 provided in the middle of the outer shell 21 is used to allow the display screen body 1 to be fitted on the surface of the middle pad 24 and installed inside the outer shell 21. The circuit storage compartment 25 provided inside the outer shell 21 is used to facilitate the placement and connection of the circuits of the display screen body 1. The surface of the display screen body 1 can be wrapped and installed by the soft pad 22 provided at the end of the outer shell 21. When maintenance is required, the soft pad 22 can be pulled around to remove the display screen body 1 for inspection. Repair, effectively improving the convenience of maintenance, when the soft pad 22 is wrapped around the surface of the display body 1, it drives a number of clips 31 fixedly connected to the inner wall of the soft pad 22 to be clamped into the clamping groove 32 opened on the surface of the outer plate 11, further improving the connection between the soft pad 22 and the surface of the display body 1, and using the magnetic gasket 5 provided on the inner wall of the clamping groove 32 and the end of the clip 31, when the clip 31 is clamped into the clamping groove 32, the stability of the connection between the clip 31 and the clamping groove 32 can be improved, thereby improving the clamping effect of the soft pad 22 on the display body 1;

[0034] The baffle 4 arranged on the inner wall of the soft pad 22 can block the upper end and the upper end of the side wall of the inner screen 12, reducing the reflection during viewing without affecting the viewing. The baffle 4 is made of elastic material and does not affect the shrinkage of the soft pad 22.
