Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted display devices, and particularly relates to a screen display of a vehicle-mounted monitoring device. Background Art

[0002] A monitoring screen refers to a device used to display video images captured by monitoring cameras. It is usually a large liquid crystal display or LED display, which can display the images of multiple cameras in real time so that monitoring personnel can observe and monitor the situation of a specific area at any time. The monitoring screen usually has characteristics such as high resolution, high brightness, and high contrast to ensure that the video images are clearly visible. It can also be connected to a computer or other devices through a network for remote monitoring and management.

[0003] A train monitoring screen refers to a monitoring system on a train, which is used to monitor the running status and parameters inside the train compartments. Since there are many compartments in the train, multiple monitoring devices need to be connected to different monitoring screens so that the staff can comprehensively view the monitoring images.

[0004] For the existing vehicle-mounted monitoring device screens used to display monitoring content, when multiple monitoring screens are running simultaneously, most of the multiple monitoring screens are arranged and distributed inside the train compartments. The multiple monitoring screens arranged and distributed have different heights, and most of them are immovable. If it is necessary to clean the heat dissipation holes behind a certain monitoring screen or perform disconnection and connection operations on the signal interface of the monitoring screen, the entire monitoring screen needs to be disassembled, and the process is relatively cumbersome. The disassembly and installation take a long time, and the operation is difficult during the train's running. Content of the Utility Model

[0005] In view of the above problems, the present application provides a screen display of a vehicle-mounted monitoring device.

[0006] To achieve the above object, the present application provides the following technical solution: A screen display of a vehicle-mounted monitoring device includes a monitoring screen distributed from top to bottom for displaying monitoring images. A support seat is provided on the back of the monitoring screen, and a group of positioning columns are provided behind the support seat. Mounting plates are provided on the positioning columns.

[0007] A plurality of alignment supports are provided on the positioning columns from top to bottom. The alignment supports are in a U-shaped structure, and the legs of the alignment supports all face the support seat. The monitoring screen and the support seat can move synchronously along the distribution direction of the legs of the alignment supports, and the alignment supports are connected to the support seat through a locking structure.

[0008] Further, a pair of hanging brackets are provided on the support seat, and the pair of hanging brackets are respectively sleeved on the legs of the alignment supports. Locking screws perpendicular to the legs are provided on the legs of the alignment supports.

[0009] The surface of the hanger is provided with a limit channel, and the part of the locking screw exposed from the alignment support penetrates through the limit channel. When the monitoring screen moves synchronously with the hanger, the limit channel moves to adjust the relative position with the locking screw.

[0010] Furthermore, the locking structure includes a moving screw arranged on the alignment support. The moving screw is parallel to the two legs of the alignment support, and connecting rods are arranged at one ends of the moving screws close to the support base. A pair of guide columns are arranged on each of the connecting rods, and the pair of guide columns are symmetrically distributed from top to bottom.

[0011] Limit grooves are provided on the surfaces of the pair of guide columns arranged on the same connecting rod, and the openings of the pair of limit grooves distributed from top to bottom face in opposite directions.

[0012] Furthermore, the locking structure further includes a turntable. A pair of clamping rods are arranged along the radial position of the turntable. The pair of clamping rods are respectively adapted to the limit grooves distributed from top to bottom. When the clamping rods rotate with the turntable, the pair of clamping rods can switch the connection state with the limit grooves.

[0013] Furthermore, receiving channels are provided on the support bases. In the natural state, the pair of guide columns arranged on the same connecting rod respectively face the upper and lower opening positions of the receiving channels. The turntables are all arranged on the support bases and extend to the inner sides of the receiving channels.

[0014] In summary, the technical effects and advantages of the present utility model are as follows:

[0015] The present utility model can maintain the stable state of the monitoring screen through the locking structure, avoiding the phenomenon of shaking and deviation of the monitoring screen during the running of the train. If it is necessary to clean the heat dissipation holes behind the monitoring screen or perform disconnection and connection operations on the monitoring screen, the monitoring screen and the support base can move synchronously along the distribution direction of the legs of the alignment support, expanding the operation space of the staff. During this process, it is not necessary to remove the entire monitoring screen, which is convenient for operation inside the carriage and improves the portability during the operation process.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: Reference Figure 1 , Figure 2 The screen display of a vehicle-mounted monitoring device shown in the figure includes a monitoring screen 1 distributed from top to bottom, which is used to display the monitoring screen. A support base 11 is provided on the back of the monitoring screen 1, and the same group of positioning columns 3 are provided behind the support base 11. The positioning columns 3 are all provided with mounting plates 2, and the mounting plates 2 are pre-set in the vehicle compartment.

[0025] A plurality of alignment supports 4 are provided on the positioning column 3 from top to bottom. The alignment supports 4 are U-shaped, and the legs of the alignment supports 4 are all facing the support seat 11. During the daily use of the monitoring screen 1, if it is necessary to clean the heat dissipation holes behind the monitoring screen 1, or to dismantle and connect the monitoring screen 1, the monitoring screen 1 and the support seat 11 can be moved synchronously along the distribution direction of the legs of the alignment supports 4, thereby expanding the operating space of the staff. During this process, there is no need to remove the entire monitoring screen 1, which is convenient for operation in the vehicle.

[0026] In the natural state, the alignment support 4 is connected to the support base 11 through a locking structure, which has a locking effect on the monitoring screen 1 and keeps the monitoring screen 1 installed inside the carriage in a stable state.

[0027] likeFigure 3 , Figure 4 As shown in Figure 4 , a pair of hanging brackets 12 are provided on the support base 11. The pair of hanging brackets 12 are respectively sleeved on the support legs of the alignment support 4. Locking screws 41 perpendicular to the support legs are provided on the support legs of the alignment support 4. A limiting channel 121 is formed on the surface of the hanging bracket 12. The part of the locking screw 41 exposed from the alignment support 4 penetrates through the limiting channel 121. When the monitoring screen 1 moves synchronously with the hanging bracket 12, the limiting channel 121 moves to adjust the relative position with the locking screw 41. The arrangement of the locking screw 41 can prevent the support base 11 and the monitoring screen 1 from detaching from the alignment support 4 during the sliding process, and maintain the stability of the support base 11 and the monitoring screen 1 when moving to the extreme extent.

[0028] As Figure 3 , Figure 4 As shown in Figure 4 , the locking structure includes a moving screw 5 provided on the alignment support 4. The moving screw 5 is parallel to the two support legs of the alignment support 4, and connecting rods 6 are provided at one end of the moving screw 5 close to the support base 11. A pair of guiding columns 7 are provided on each connecting rod 6. The pair of guiding columns 7 are symmetrically distributed from top to bottom. During the initial installation of the monitoring screen 1, only need to rotate the moving screw 5 to a specified position to make the connecting rod 6 and the guiding column 7 close to the support base 11. Limiting grooves 71 are formed on the surfaces of the pair of guiding columns 7 provided on the same connecting rod 6. The openings of the pair of limiting grooves 71 distributed from top to bottom face in opposite directions. The formation of the limiting grooves 71 can restrict the movement of the components inside their grooves.

[0029] As Figure 5 As shown in Figure 5 , the locking structure further includes a turntable 8. A pair of clamping rods 9 are provided along the radial position of the turntable 8. The pair of clamping rods 9 are respectively adapted to the limiting grooves 71 distributed from top to bottom. When the clamping rods 9 rotate with the turntable 8, the pair of clamping rods 9 can switch the connection state with the limiting grooves 71. Therefore, during the daily use of the monitoring screen 1, by connecting the clamping rods 9 with the limiting grooves 71, the support base 11 and the monitoring screen 1 can be locked to maintain their stable states, and prevent the monitoring screen 1 from shaking and shifting during the train running process.

[0030] If it is necessary to move the monitoring screen 1 for wiring and cleaning operations, only need to control the rotation of the turntable 8 to make the clamping rods 9 disengage from the limiting grooves 71. The support base 11 and the monitoring screen 1 can move away from the guiding column 7 smoothly. The staff can smoothly pull the monitoring screen 1 apart, so as to facilitate operations such as disassembly, wiring and cleaning of the monitoring screen 1. This expands the operation space of the staff. During this process, there is no need to remove the entire monitoring screen 1, improving the portability during the operation process.

[0031] As Figure 5As shown, in order to facilitate the placement of the turntable 8 and the clamping rods 9, accommodation channels 111 are respectively formed in the support base 11. In the natural state, a pair of guide posts 7 provided on the same connecting rod 6 respectively face the upper and lower opening positions of the accommodation channels 111. The turntables 8 are respectively arranged on the support base 11 and extend to the inner sides of the accommodation channels 111. When the clamping rods 9 are disengaged from the limiting grooves 71, the clamping rods 9 are respectively located inside the accommodation channels 111, leaving a space for the support base 11 and the monitoring screen 1 to move smoothly away from the guide posts 7.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
