DETAILED DESCRIPTION

[0034] This embodiment is a preferred implementation of the present utility model. Other embodiments whose principles and basic structures are the same or similar to those of this embodiment are within the protection scope of the present utility model.

[0035] Please refer to the attached Figure 1 To the attached Figure 6 This utility model primarily protects a mounting bracket for an LED display module. The mounting bracket utilizes a plastic skeleton structure formed through an injection molding process. The LED display module in this utility model includes a light panel, which is the primary component for display. The mounting bracket functions similarly to a conventional housing, used to mount the LED display module and other structures (such as a control module). The LED display module and mounting bracket form a display unit. Multiple display units can be assembled to form a single LED display screen by attaching them to a steel structure bracket through magnetic attraction or other means.

[0036] The present invention mainly includes an intermediate main body frame and an auxiliary frame connected to at least one side of the main frame; the main frame includes two cross bars 12 arranged at intervals and a plurality of main connecting rods 11 connected between the two cross bars 12 and spaced from each other, at least one of the cross bars 12 is provided with a first mounting hole 13, and at least two of the main connecting rods 11 are provided with a controller mounting hole 17; the auxiliary frame includes two side bars 19, one end of the two side bars 19 is directly or indirectly connected, and the other ends of the two side bars 19 are respectively connected to the corresponding cross bars 12, and the two side bars 19 are respectively provided with a second mounting hole 14 for a display screen; wherein, the first mounting hole 13 and the second mounting hole 14 are used to connect to the LED display module located on the front side of the fixed bracket, and the controller mounting hole 17 is used to connect to the controller located on the rear side of the fixed bracket.

[0037] In this embodiment, the two side rods 19 are preferably connected to the end positions of the cross bar 12. In specific implementation, the two side rods 19 may not be connected to the end positions of the cross bar 12, but may be connected to appropriate positions on the cross bar 12.

[0038] In this embodiment, the auxiliary frames are connected to opposite sides of the main frame, and the two auxiliary frames are symmetrically arranged along the transverse axis of the main frame. In specific implementation, the auxiliary frame can also be connected and arranged on only one side (upper or lower side) of the main frame.

[0039] The following structure is described by taking the auxiliary frames connected to the upper and lower sides as an example. This embodiment can be structurally divided into three parts: the middle main part (main frame), the upper part (that is, the upper auxiliary frame) and the lower part (that is, the lower auxiliary frame). The three parts are arranged in one body. For the convenience of description, they are structurally defined as three parts. The central body portion is the main component of the present invention, namely the main body frame. The main body frame structurally includes a main body connecting rod 11, a main body upper crossbar (not separately numbered), and a main body lower crossbar (not separately numbered) disposed on either side. The two main body connecting rods 11, the main body upper crossbar, and the main body lower crossbar disposed on either side are connected end to end to form a "mouth"-shaped central body frame. A main body inner rod 111 (a type of main body connecting rod 11, disposed within the main body frame, and therefore defined as a main body inner rod) is fixedly disposed within the main body frame. Two main body inner rods 111 are provided, and the two main body inner rods 111 are respectively disposed parallel to the main body connecting rods 11 on either side. In this embodiment, preferably, the distance between the main body connecting rods 11 is the same, so that the two main body connecting rods 11, the two main body inner rods 111, the main body upper crossbar, and the main body lower crossbar collectively form a "eye"-shaped structure. In this embodiment, two main body inner rods 111 are provided, but in specific implementation, one or more main body inner rods 111 may be provided as needed.

[0040] In this embodiment, at least two main connecting rods 11 (including the main connecting rods 11 on both sides and the main inner rod 111) are respectively provided with a controller mounting hole 17 at their upper and lower ends. The controller mounting hole 17 is used to install the controller. In this embodiment, a total of eight controller mounting holes 17 are provided. In specific implementation, one, three, or more controller mounting holes 17 can be provided on the main connecting rods 11 on both sides and the main inner rod 111 according to actual needs. As long as it is convenient for the installation of the controller, all or some of the controller mounting holes 17 can be used. The unused parts can be left hanging. In this embodiment, an outwardly protruding arc-shaped bulge is provided on the main connecting rod 11 at the position corresponding to the controller mounting hole 17. In other words, the main connecting rod 11 is thickened at the position corresponding to the controller mounting hole 17 to increase the local strength of the main connecting rod 11 and prevent damage to the main connecting rod 11 at the position of the controller mounting hole 17.

[0041] In this embodiment, a circle of first raised rings 18 is provided around the controller mounting hole 17. The first raised rings 18 protrude from the rear surfaces of the main frame and the auxiliary frame. When the controller is installed, the first raised rings 18 can prop up the controller to prevent contact between the controller and the fixing bracket 1 and damage to the parts on the controller. In this embodiment, the controller mounting hole 17 is a circular through hole. When in use, the controller mounting screws can be self-tapping screws. The self-tapping screws can be directly installed in the controller mounting hole 17 to achieve the effect of fixing the controller. In specific implementation, the controller mounting hole 17 can also be a threaded hole or a nut can be embedded in the controller mounting hole 17. The nut cooperates with the ordinary screw to achieve the installation of the controller. When the controller mounting hole 17 is a circular through hole, the first raised ring 18 can serve as an extension of the controller mounting hole 17, making it more secure.

[0042] In the present invention, the side where the fixing bracket cooperates with the LED display module is the front side, and the corresponding surface is defined as the front surface; the side where the fixing bracket cooperates with the control box is the rear side, and the corresponding surface is defined as the rear surface.

[0043] In this embodiment, the auxiliary frame mainly includes side rods 19 and inner connecting rods 110. The side rods 19 include two, one end of each of the two side rods 19 is directly or indirectly connected, and the bottom of each of the two side rods 19 is fixedly connected to one end of the cross bar 12. The two side rods 19 and the cross bar 12 together form an approximate isosceles triangle, which is the basic shape of the auxiliary frame. In this embodiment, the shape of the auxiliary frame is only an approximate isosceles triangle, not a true isosceles triangle. The ends of the two side rods 19 away from the main frame are connected by a concave arc-shaped connecting portion 117. Due to the short length of the concave arc-shaped connecting portion 117, the auxiliary frame looks like an isosceles triangle. The inner connecting rod 110 is arranged parallel to the cross bar 12, and the two ends of the inner connecting rod 110 are respectively connected to the middle position of the two side rods 19.

[0044] In this embodiment, the first mounting hole 13 is provided at the connection between the cross bar 12 and the side bar 19, and the second mounting hole 14 is provided at the end of each side bar 19 away from the main frame. Since the end of the side bar 19 may be connected to an appropriate position on the cross bar 12 rather than the end position, at this time, the first mounting hole 13 is provided on the cross bar 12 rather than on the side bar 19. When the end of the side bar 19 is connected to the end position of the cross bar 12, the first mounting hole 13 can be described as being provided on the cross bar 12, or as being provided on the side bar 19.

[0045] In this embodiment, a first sunken groove 15 is provided around the first mounting hole 13 on the rear surface of the crossbar 12, and a second sunken groove 16 is provided around the second mounting hole 14 on the rear surface of the crossbar 12. When in use, the screw head for mounting the display module can be set in the first sunken groove 15 and the second sunken groove 16 so that it does not protrude from the surface of the crossbar 12, or it does not protrude too much from the surface of the crossbar 12, so that it does not affect the installation of the controller. In this embodiment, a circle of second convex rings 116 are provided at positions around the front surface of the crossbar 12 corresponding to the first mounting hole 13 and the second mounting hole 14. The second convex rings 116 can raise the distance between the fixed bracket 1 and the display module 2 to a certain height. On the one hand, it can achieve the heat dissipation requirements between the fixed bracket 1 and the display module 2. On the other hand, it will not cause the fixed bracket 1 to press on the display module 2 due to production errors of the fixed bracket 1, thereby causing damage to the display module 2. In this embodiment, the first mounting hole 13 and the second mounting hole 14 are circular through holes. When in use, the display module mounting screws can directly pass through the first mounting hole 13 and the second mounting hole 14 to fix the display module. In specific implementation, the first mounting hole 13 and the second mounting hole 14 can also be threaded holes or nuts can be embedded in the first mounting hole 13 and the second mounting hole 14.

[0046] The auxiliary frame structure will be described in detail below with respect to the upper part and the lower part respectively.

[0047] In this embodiment, the upper portion is arranged above the middle main body portion (in this utility model, the upper portion is arranged above the middle main body portion). Figure 1 The direction in the description is defined as the direction. In actual use of the present invention, the direction of use is usually the same as the direction of the attached Figure 1 (The same orientation as shown in the figure) The upper portion primarily comprises upper side bars (not individually numbered) and upper inner connecting bars (not individually numbered). The upper side bars comprise two, the tops of which are directly or indirectly connected together. The bottoms of the two upper side bars are each fixedly connected to one end of the upper crossbar of the main body. Together, the two upper side bars and the upper crossbar of the main body form an approximate isosceles triangle, which is the basic shape of the upper portion. In this embodiment, the upper auxiliary frame only approximates an isosceles triangle, not a true isosceles triangle. The tops of the two upper side bars are connected by a concave arc-shaped connecting portion 117. Due to the short length of the concave arc-shaped connecting portion 117, the upper portion of the fixed bracket 1 appears to be an isosceles triangle.

[0048] In this embodiment, a first mounting hole 13 is defined at the lower end of the upper rod, and a second mounting hole 14 is defined at the upper end of the upper rod for attaching the fixing bracket to the display module. The first mounting hole 13 is defined at the connection between the upper rod and the upper crossbar of the main body, while the second mounting hole 14 is defined at the upper end of the upper rod.

[0049] In this embodiment, the upper inner connecting rod is arranged parallel to the upper cross rod of the main body, and both ends of the upper inner connecting rod are respectively connected to the middle position of the upper side rod.

[0050] In this embodiment, the lower portion is disposed below the central main body and primarily comprises a lower side rod (not individually numbered) and a lower inner connecting rod (not individually numbered). The lower side rods comprise two, the bottoms of which are directly or indirectly connected together. The bottoms of the two lower side rods are each fixedly connected to one end of the lower crossbar of the main body. Together, the two lower side rods and the lower crossbar of the main body form an approximate isosceles triangle, which is the basic shape of the lower auxiliary frame. In this embodiment, the shape of the lower auxiliary frame is only an approximate isosceles triangle, not a true isosceles triangle. The bottoms of the two lower side rods are connected by a concave arc-shaped connecting portion 117. Due to the relatively short length of the concave arc-shaped connecting portion 117, the upper auxiliary frame appears to be an isosceles triangle.

[0051] In this embodiment, a first mounting hole 13 is defined at the upper end of the lower bar, and a second mounting hole 14 is defined at the lower end of the lower bar for attaching the fixing bracket to the display module. The first mounting hole 13 is defined at the connection between the lower bar and the lower crossbar of the main body, while the second mounting hole 14 is defined at the lower end of the lower bar.

[0052] In this embodiment, the lower inner connecting rod is arranged parallel to the lower cross rod of the main body, and both ends of the lower inner connecting rod are respectively connected to the middle position of the lower side rod.

[0053] In this embodiment, a blind hole 114 is provided in the fixing bracket 1 to reduce the overall weight of the fixing bracket 1. In this embodiment, the blind holes 114 are provided in the main connecting rod 11, the cross rod 12, the side rods 19, the inner connecting rod 110, and the center rod 113. In a specific implementation, blind holes 114 may be selectively provided in a portion of the rods. In this embodiment, the blind holes 114 are preferably circular holes. In a specific implementation, square holes, oval holes, strip holes, triangular holes, etc. may also be used. The diameter of the blind hole 114 is 1 / 3 to 1 / 2 of the width of the rod in which it is located. For example, the ratio of the diameter of the blind hole 114 provided in the main connecting rod 11 to the width of the main connecting rod 11 is 1:3 to 1:2. In a specific implementation, other ratios may also be used. In this embodiment, to balance the strength and weight of the fixing bracket 1, the diameter of the blind hole 114 is preferably 1 / 3 of the width of the rod in which it is located. Blind holes 114 are provided on both sides of the fixed bracket 1, with the blind holes 114 arranged opposite each other. Preferably, the depth of a single blind hole 114 is 1 / 3 to 1 / 2 of the thickness of the fixed bracket 1. To balance the strength and weight of the fixed bracket 1, the diameter of a single blind hole 114 is preferably 1 / 3 of the thickness of the rod on which it is located. In this embodiment, the distance between the centers of adjacent blind holes 114 is preferably twice the diameter of the blind holes 114. Other spacings, such as 1.5 times or 3 times, may also be used in practice.

[0054] In this embodiment, a direction indicator 115 is provided on the fixed bracket 1. The direction indicator 115 is in the form of an arrow. In specific implementation, other forms of direction indicators may also be used. The direction indicator 115 can indicate the direction of use of the utility model, which can better cooperate with the display module and controller. In this embodiment, the direction indicator 115 is located at the top of the center rod 113. In specific implementation, it can also be located at other locations.

[0055] The present invention also protects an LED display screen, which includes an LED display module 2, a controller 3 and a fixing bracket 1. The fixing bracket 1 is the above-mentioned fixing bracket, wherein the front side of the fixing bracket 1 can be selectively connected to one or more of the LED display modules 2 through the first mounting hole 13 and / or the second mounting hole 14, and the rear side of the fixing bracket is connected to the controller 3 through the controller mounting hole 17.

[0056] The LED display screen structure will be further described below with two groups of specific embodiments.

[0057] Please refer to the attached Figure 7 To the attached Figure 11The fixing bracket 1 of the present invention is fixedly mounted on a display module 2 to form a single-module housing. The display module 2 is provided with display module screw holes 21. The display module mounting screws are inserted through the first mounting holes 13 and / or the second mounting holes 14 on the fixing bracket 1 and installed in the display module screw holes 21, thereby securing the fixing bracket 1 and the display module 2 together. The controller 3 is then secured to the controller mounting holes 17 using screws 31, securing the fixing bracket 1 and the controller 3 together.

[0058] Since the display module 2 and controller 3 both adopt a standard design and their mounting holes also have certain standard positions, the display module mounting holes 15 and controller mounting holes 17 in the present invention are also positioned in accordance with the standard positions. In practice, if the display module 2 and controller 3 adopt non-standard designs, the display module 2 and controller 3 can also be installed in the blind holes 114 using screws.

[0059] Please refer to the attached Figure 12 and attached Figure 13 The fixing bracket 1 in the present invention is fixedly installed between the two display modules, and the two display modules are installed together through the fixing bracket 1 to form a minimalist box structure. In this embodiment, the two display modules are defined as the first display module 4 and the second display module 5 respectively. During assembly, the first display module 4 and the second display module 5 are brought close together and arranged side by side, and then the fixing bracket 1 is set at the middle position between the first display module 4 and the second display module 5, and it is locked to the corresponding hole positions of the first display module 4 and the second display module 5 by screws, wherein the right part of the fixing bracket 1 is fixedly installed with the first display module 4, and the left part of the fixing bracket 1 is fixedly installed with the second display module 5. The first display module 4 and the second display module 5 are locked together to form a simple unit box. Then, the controller 3 is fixedly installed at the controller mounting hole 17 by screws 31, so that the fixing bracket 1 and the controller 3 are fixedly installed together.

[0060] Later, magnets can be installed on both sides of the simple unit box, and it can be directly attached to the steel structure to assemble a large screen.

[0061] When the present invention is used, in addition to the above-mentioned single-module box structure and simple unit box structure, the fixed bracket 1 can also be used in splicing screens of other structures, such as: in a splicing screen with a parallel structure, the splicing points of adjacent display modules are fixed and spliced ​​by the fixed bracket 1; in a splicing screen with a "field" structure or a larger splicing screen, the "cross" splicing points of each display module are fixed and spliced ​​by the fixed bracket 1 to form an overall splicing screen. When there are multiple fixed brackets 1 in the entire splicing screen, it is not necessary to set the controller 3 on each fixed bracket 1, but only to set the controller 3 on one or more required fixed brackets 1.

[0062] The present invention can be used in a single-module box for installation with a single display module, or in a dual-module box for installation with two display modules. In addition to being able to securely mount the display module, the present invention can also be used to securely mount the controller.

[0063] The utility model is processed by injection mold and is made of plastic material. Not only is the processing process simple and fast, but it also ensures that the entire product is light in weight, cheap in price, and high in product strength.
