Description

Technical Field

[0001] The utility model relates to the field of display technology, in particular to a combined installation mechanism and a display device. Background Art

[0002] In the transportation industry, traffic information display screens are mounted on poles beside the road. The front of the display screen is used to display images, and the back of the display screen is provided with an openable maintenance door. In order to connect the display screen to the pole while avoiding the maintenance door, two beams (upper beam and lower beam) are usually provided on the pole. The upper beam is connected to the upper end of the display screen, and the lower beam is connected to the lower end of the display screen. The maintenance door is located between the upper beam and the lower beam.

[0003] However, a significant portion of existing poles, such as electronic police poles, are single-beam. This single beam needs to be connected to the back of the traffic information display, preventing the maintenance door on the back of the display from opening properly. Therefore, existing traffic information displays are incompatible with these single-beam poles. Rebuilding new poles with dual beams would inevitably result in a waste of resources.

[0004] If the display module of the display screen is combined with the maintenance door on the front of the display screen so that the front of the display screen can be opened and closed, the existing traffic display screen can be mounted on a single beam. However, for displays with a larger display area, the size and weight of the maintenance door will exceed the rated load of the maintenance door hinge. At the same time, after the maintenance door is opened, the torque generated by the opening maintenance door on the single beam and column due to the influence of gravity may cause the column to overturn.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] Example 1

[0038] Combine Figures 1 to 4 as well as Figure 11 , schematically shows the combined mounting mechanism of the present invention, including a base frame 10 and a plurality of mounting units 20. In this embodiment, there are two mounting units 20, which are arranged in parallel.

[0039] Among them, Figure 2 The mounting unit 20 includes a movably connected housing 21 and a cover 22. The housing 21 and the cover 22 are rotatably connected via a rotating shaft. The housing 21 has an opening 211 communicating with its interior, and the cover 22 is configured to cover the opening 211. The housing 21 may contain electronic components such as a power module, a control circuit board, and a cooling fan. Multiple display modules 40 may be mounted on the outer side of the cover 22. The multiple display modules 40 on the cover 22 are arranged in a matrix and can be combined to display a common image. Maintenance personnel can open the cover 22 to access the electronic components within the housing 21, or disassemble or maintain the display modules 40 on the cover 22.

[0040] like Figure 2 and Figure 11A connecting component 11 for connecting the crossbeam 50 is provided on one side of the base frame 10, and the shells 21 of multiple mounting units 20 are detachably arranged on the other side of the base frame 10. The connecting component 11 and the opening 211 are arranged back to back, so the opening and closing of the cover 22 of the mounting unit 20 does not interfere with the connecting component 11. The connecting component 11 can be connected to the single crossbar or double crossbar of the existing traffic pole, which makes the combined mounting mechanism adaptable to more different types of traffic poles, greatly expanding the application range of the combined mounting mechanism.

[0041] At the same time, the provision of multiple mounting units 20 enables the size and weight of the cover 22 on each mounting unit 20 to be controlled (the size and weight of the cover 22 are smaller than the size and weight of the back maintenance door or front cover of the existing traffic information display screen), so as to prevent the cover 22 from being too large and causing the existing traffic pole to overturn after it is opened.

[0042] Specifically, if Figure 1 and Figure 4 The combined mounting mechanism further includes a sliding guide assembly, which includes a guide rail 12 and a guide wheel 212 that are movably coupled together. The guide rail 12 is provided on the base frame 10, and the guide wheel 212 is rotatably connected to the housing 21. Each housing 21 is provided with a plurality of guide wheels 212, so that the housing 21 can slide relative to the base frame 10 under the guidance of the guide rail 12, thereby achieving assembly and disassembly of the housing 21 from the base frame 10, or adjusting the position of the housing 21 on the base frame 10. When the cover 22 is closed, the guide rail 12 can be arranged in a direction parallel to the cover 22 or perpendicular to the cover 22, both of which can achieve the above-mentioned functions of assembly and disassembly and position adjustment of the housing 21.

[0043] In addition, the base frame 10 is provided with a plurality of mutually parallel reinforcing ribs 14 , which improve the rigidity and strength of the base frame 10 so that the base frame 10 can carry a larger number of mounting units 20 or heavier mounting units 20 .

[0044] Example 2

[0045] Combine Figures 1 to 11As shown, the difference between this embodiment and embodiment 1 is that the sliding tracks between each shell 21 and the base frame 10 overlap with each other. In other words, a plurality of guide rails 12 are provided on the base frame 10. If there are multiple guide rails 12, the multiple guide rails 12 are parallel to each other, and the shell 21 is movably connected to the guide rail 12 through the guide wheel 212. The shells 21 of multiple installation units 20 can slide along the arrangement direction of the guide rail 12 through the guide wheel 212. For example, when a guide rail 12 is provided on the base frame 10, the shells 21 of multiple installation units 20 can all slide on the guide rail 12. When the shell 21 slides to the end of the guide rail 12, the end of the guide rail 12 allows the guide wheel 212 on the shell 21 to disengage from the guide rail 12, so as to facilitate the separation of the shell 21 from the base frame 10.

[0046] In this embodiment, if Figure 4 and Figure 8 As shown, the cross section of the guide rail 12 is U-shaped, and the guide wheel 212 is slidably embedded in the guide rail 12. Under the guidance of the guide rail 12, the guide wheel 212 can only slide relative to the guide rail 12 along the extension direction of the guide rail 12.

[0047] like Figure 3 The base frame 10 is provided with a square ring-shaped frame 13, i.e., the frame 13 is rectangular. Multiple mounting units 20 are located inside the frame 13. Two guide rails 12 are provided on the frame 13. The two guide rails 12 are parallel to each other and arranged opposite each other. The two guide rails 12 are respectively arranged on two opposite sides of the frame 13. Correspondingly, multiple guide wheels 212 are provided at both ends of the housing 21, so that both ends of the housing 21 can be connected to the corresponding guide rails 12 through the guide wheels 212.

[0048] like Figure 6 and Figure 7 In order to align the two adjacent shells 21, a guide component 215 extending toward the shell 21 of the adjacent installation unit 20 is provided on the shell 21, and the guide component 215 has a guide slope 215a, which is inclined to the sliding track between the shell 21 and the base 10. In the process of the two shells 21 moving toward each other, one side of one shell 21 will first abut against the guide slope 215a, and the guide slope 215a guides the movement of the adjacent shell 21, and finally makes one side of the guide component 215 slidably abut against the adjacent shell 21, thereby aligning the two adjacent shells 21, which makes it possible to align the display module 40 installed on the cover 22 corresponding to the shell 21, thereby ensuring the display quality of the display screen.

[0049] Combine Figure 1 、 Figure 3 and Figure 10As shown, in order to further limit the degree of freedom of the shell 21 to prevent the shell 21 from accidentally falling off from the end of the guide rail 12 during normal use, the combined mounting mechanism also includes a limiting component 30, which is located on the sliding track between the shell 21 and the base 10, that is, the limiting component 30 is located at the end of the guide rail 12, and the two sides of the limiting component 30 are respectively connected to the shell 21 and the base 10. In this embodiment, there are two mounting units 20, and the shells 21 of the two mounting units 20 are arranged side by side and abut against each other. There are two limiting components 30, one of which is located between one of the shells 21 and the base 10, and the other limiting component 30 is located between the other shell 21 and the base 10. The two limiting components 30 clamp and limit the two shells 21 therebetween.

[0050] Furthermore, if Figure 10 The base frame 10 is provided with a limiting hole 15, and the limiting component 30 is provided with a slot 31. Existing fasteners such as bolts are passed through the limiting hole 15 and the slot 31 to fasten the base frame 10 and the limiting component 30 to prevent relative movement between the base frame 10 and the limiting component 30. The provision of the slot 31 allows the limiting component 30 to be finely adjusted relative to the base frame 10 between the fasteners being fastened, to ensure that the limiting component 30 abuts against the housing 21. When the fasteners are removed, the limiting component 30 can be separated from the base frame 10. The limiting component 30 no longer blocks the housing 21, and the housing 21 can then slide relative to the guide rail 12 via the guide wheel 212 and separate from the guide rail 12 at the end of the guide rail 12.

[0051] Combine Figure 2 、 Figure 5 and Figure 9 As shown, in order to secure the cover 22 and the housing 21, and in particular to keep the cover 22 closed, the housing 21 is provided with a locking member having a locking hole 214 and a locking catch 213 connected thereto. The locking catch 213 is rotatably connected to the housing 21. A connecting hole is provided on the cover 22. When the locking catch 213 rotates forward relative to the housing 21, the end of the locking catch 213 penetrates the connecting hole and engages with each other in the connecting hole, thereby locking the cover 22 and the housing 21. Conversely, when the locking catch 213 rotates backward relative to the housing 21, the end of the locking catch 213 disengages the connecting hole, thereby unlocking the cover 22 and the housing 21. The locking hole 214 is arranged toward the housing 21 of the adjacent mounting unit 20. When the two adjacent housings 21 abut against each other, the locking hole 214 is blocked by the side of the adjacent housing 21, thereby preventing the cover 22 from being opened by accident and preventing criminals from maliciously unlocking the locking member.

[0052] Example 3

[0053] like Figure 11 and Figure 12This embodiment provides a display device, including a crossbeam 50 and the above-mentioned combined mounting mechanism. The cover 22 of each mounting unit 20 is provided with a plurality of display modules 40 arranged in a matrix. The plurality of display modules 40 on the plurality of mounting units 20 are spliced ​​together to form a display screen with a larger display area; the connecting component 11 on the base frame 10 is detachably connected to the crossbeam 50.

[0054] To sum up, the mounting unit 20 has a shell 21 and an openable and closable cover 22. The cover 22 can be used to install the display module 40. A connecting component 11 is provided on one side of the base frame 10. The connecting component 11 is used to connect the existing single beam 50 or double beam 50, so that the application range of the combined mounting mechanism is wider and it is conducive to a wide range of applications. The shells 21 of multiple mounting units 20 are detachably arranged on the other side of the base frame 10, and the connecting component 11 and the opening 211 of the shell 21 are arranged back to back. The opening and closing of the cover 22 does not interfere with the existing beam 50, and multiple mounting units 20 all have their own cover 22, which can reduce the size and weight of a single cover 22 to prevent the cover 22 from being too large in size and weight and causing the existing traffic pole to overturn after it is opened.

[0055] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
