Description

Technical Field

[0001] This invention relates to the field of LED display devices, and more specifically, to an LED display device and its positioning component. Background Technology

[0002] In related technologies, LED display devices are generally composed of multiple LED cabinets arranged in an array. Adjacent LED cabinets are aligned front to back by beading and recesses set on the sides of the LED cabinets.

[0003] However, due to errors in the processing and assembly of LED cabinets, and the fact that LED cabinets (especially the sides) are prone to deformation during storage and transportation, there is often a height difference between adjacent LED cabinets. This makes it impossible for the final assembled LED display device to form an ideal plane, affecting the display effect of the LED display device. Summary of the Invention

[0004] The main objective of this invention is to provide an LED display device and its positioning components to solve the problem in related technologies where the assembled LED display device cannot form an ideal plane due to processing and assembly errors and deformation of the LED cabinet.

[0005] To achieve the above objectives, according to one aspect of the present invention, a positioning assembly for an LED display device is provided. The LED display device includes a first LED housing and a second LED housing. The positioning assembly connects the first LED housing and the second LED housing. The positioning assembly includes: a first positioning block connected to the rear side of the first LED housing and having a first positioning surface and a first connecting hole, the first positioning block abutting against the rear surface of the first LED housing through the first positioning surface; a second positioning block connected to the rear side of the second LED housing and having a second positioning surface and a second connecting hole, the second positioning block abutting against the rear surface of the second LED housing through the second positioning surface; and a connecting pin capable of simultaneously passing through the first connecting hole and the second connecting hole to position the first positioning block and the second positioning block.

[0006] Furthermore, a first snap-fit ​​part is provided in the first connecting hole, a second snap-fit ​​part is provided in the second connecting hole, and a third snap-fit ​​part is provided on the connecting pin to engage with the first snap-fit ​​part and the second snap-fit ​​part.

[0007] Furthermore, the first locking portion includes a first elastic arm and a first locking block disposed at the free end of the first elastic arm; the second locking portion includes a second elastic arm and a second locking block disposed at the free end of the second elastic arm; and the third locking portion includes a plurality of locking recesses spaced apart along the length direction of the connecting pin. When the connecting pin positions the first positioning block and the second positioning block, the first locking block is located in one of the locking recesses, and the second locking block is located in another locking recess among the multiple locking recesses.

[0008] Furthermore, a first clearance notch is provided on the wall of the first connecting hole, and a first snap-fit ​​part is disposed within the first clearance notch; and / or, a second clearance notch is provided on the wall of the second connecting hole, and a second snap-fit ​​part is disposed within the second clearance notch.

[0009] Furthermore, the first positioning block includes a first main body and a second main body. The first main body is provided with a receiving recess, and the second main body is disposed in the receiving recess. The inner wall of the receiving recess is provided with a first groove, and the side wall of the second main body is provided with a second groove. The first groove and the second groove are joined together to form a first connecting hole. The groove wall of the first groove or the second groove is provided with a first clearance notch, and the first snap-fit ​​part is disposed in the first clearance notch.

[0010] Furthermore, the first positioning block includes a first main body and a second main body. The first main body is provided with a receiving recess, and the second main body is disposed in the receiving recess. The first positioning block also includes a mounting part disposed on the first main body. The mounting part is provided with a mounting hole. The first positioning block is connected to the first LED housing by fasteners passing through the mounting hole. The bottom surface of the first main body, the bottom surface of the second main body, and the bottom surface of the mounting part together form the first positioning surface.

[0011] Furthermore, the side wall of the connecting pin is provided with an anti-detachment groove extending along its length direction, and the first positioning block or the second positioning block is provided with an anti-detachment pin passing through the anti-detachment groove. The connecting pin can be connected to the first positioning block or the second positioning block, and the anti-detachment pin can cooperate with the end wall stop in the length direction of the anti-detachment groove to prevent the connecting pin from detaching from the first positioning block or the second positioning block.

[0012] Furthermore, the cross-sectional shape of the first connecting hole and the second connecting hole is elliptical or polygonal.

[0013] Furthermore, a handle is provided at one end of the connecting pin, and the handle extends in a direction away from the first positioning surface.

[0014] The present invention also provides an LED display device, including a first LED housing, a second LED housing, and a positioning component connected between the first LED housing and the second LED housing, wherein the positioning component is the aforementioned positioning component.

[0015] Applying the technical solution of this invention, the first positioning block is connected to the rear side of the first LED cabinet via a first positioning surface to ensure the relative positional relationship between the first positioning block and the first LED cabinet; the second positioning block is connected to the rear side of the second LED cabinet via a second positioning surface to ensure the relative positional relationship between the second positioning block and the second LED cabinet. The first positioning block and the second positioning block are connected together by connecting pins passing through the first and second connecting holes, thereby ensuring the relative positional relationship between the first positioning block and the second positioning block, and thus ensuring the relative positional relationship between adjacent first and second LED cabinets. Since the rear surface of the LED cabinet is not easily deformed, the connection between the positioning component and the rear surface of the first and second LED cabinets ensures that the relative positions between the positioning component, the first LED cabinet, and the second LED cabinet meet the requirements, thereby ensuring that the assembled LED display device can form a relatively ideal plane, and thus ensuring the display effect of the LED display device. Therefore, the technical solution of this application can effectively solve the problem in related technologies where the assembled LED display device cannot form an ideal plane due to processing and assembly errors and deformation of the LED cabinet.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 3 as well as Figure 9 and Figure 10As shown, the LED display device includes a first LED housing 10 and a second LED housing 20. In this embodiment, a positioning component connects the first LED housing 10 and the second LED housing 20. The positioning component includes a first positioning block 30, a second positioning block 40, and a connecting pin 50. The first positioning block 30 is connected to the rear side of the first LED housing 10 and has a first positioning surface 33 and a first connecting hole. The first positioning block 30 abuts against the rear surface of the first LED housing 10 through the first positioning surface 33. The second positioning block 40 is connected to the rear side of the second LED housing 20 and has a second positioning surface 43 and a second connecting hole 42. The second positioning block 40 abuts against the rear surface of the second LED housing 20 through the second positioning surface 43. The connecting pin 50 can simultaneously pass through the first connecting hole and the second connecting hole 42 to position the first positioning block 30 and the second positioning block 40.

[0031] Applying the technical solution of this embodiment, the first positioning block 30 is connected to the rear side of the first LED cabinet 10 via the first positioning surface 33 to ensure the relative positional relationship between the first positioning block 30 and the first LED cabinet 10; the second positioning block 40 is connected to the rear side of the second LED cabinet 20 via the second positioning surface 43 to ensure the relative positional relationship between the second positioning block 40 and the second LED cabinet 20. The first positioning block 30 and the second positioning block 40 are connected together by connecting pins 50 passing through the first connecting hole and the second connecting hole 42, thereby ensuring the relative positional relationship between the first positioning block 30 and the second positioning block 40, and thus ensuring the relative positional relationship between adjacent first LED cabinets 10 and second LED cabinets 20. Since the rear surface of the LED cabinet is not easily deformed, the connection between the positioning component and the rear surface of the first LED cabinet 10 and the second LED cabinet 20 can ensure that the relative position between the positioning component, the first LED cabinet 10 and the second LED cabinet 20 meets the requirements, thereby ensuring that the spliced ​​LED display device can form a relatively ideal plane, and thus ensuring the display effect of the LED display device. Therefore, the technical solution of this embodiment can effectively solve the problem in related technologies that the assembled LED display device cannot form an ideal plane due to processing and assembly errors and deformation of the LED cabinet.

[0032] It should be noted that the aforementioned "positioning the first positioning block 30 and the second positioning block 40" refers to fixing the relative positions of the first positioning block 30 and the second positioning block 40 through the connecting pin 50. In this embodiment, since the first positioning surface 33, the first connecting hole, the second positioning surface 43, the second connecting hole 42, and the connecting pin 50 are the main structures for achieving positioning, the surface machining accuracy requirements for these structures are high, while the surface machining accuracy requirements for other structures are not specified.

[0033] The aforementioned "LED display device cannot form an ideal plane" refers to the fact that the front surface (the side facing the viewer) of multiple LED cabinets in the LED display device cannot form an ideal plane.

[0034] like Figures 1 to 3 As shown, a first engaging portion 61 is provided in the first connecting hole, a second engaging portion 62 is provided in the second connecting hole 42, and a third engaging portion 63 is provided on the connecting pin 50 to engage with the first engaging portion 61 and the second engaging portion 62. The engaging engagement between the first engaging portion 61 and the third engaging portion 63, and between the second engaging portion 62 and the third engaging portion 63, enables the positioning of the first positioning block 30 and the second positioning block 40, thereby ensuring that their relative positions are fixed.

[0035] like Figures 1 to 3 As shown, in this embodiment, the first locking portion 61 includes a first elastic arm 611 and a first locking block 612 disposed at the free end of the first elastic arm 611; the second locking portion 62 includes a second elastic arm 621 and a second locking block 622 disposed at the free end of the second elastic arm 621; and the third locking portion 63 includes a plurality of locking recesses 631 spaced apart along the length direction of the connecting pin 50. When the connecting pin 50 positions the first positioning block 30 and the second positioning block 40, the first locking block 612 is located in one of the locking recesses 631, and the second locking block 622 is located in another locking recess 631. The positioning of the first positioning block 30 and the second positioning block 40 is achieved through the locking engagement between the elastic arms (first elastic arm 611 and second elastic arm 621) and the locking blocks (first locking block 612 and second locking block 622) disposed at the free end of the elastic arms and the locking recesses 631, which has the advantage of simple structure. Specifically, in this embodiment, the first locking block 612 and the second locking block 622 are hemispherical structures, which facilitates the operator to insert and remove the connecting pin 50.

[0036] like Figure 2 , Figure 3 and Figure 8 As shown, the snap-fit ​​recess 631 includes a first snap-fit ​​recess 6311, a second snap-fit ​​recess 6312, and a third snap-fit ​​recess 6313 arranged sequentially and at equal intervals along the length of the connecting pin 50. When the connecting pin 50 is only inserted into the first connecting hole (see...), Figure 2 The first locking block 612 engages with the third locking recess 6313. When the connecting pin 50 is simultaneously inserted into the first connecting hole and the second connecting hole 42 and positions the first positioning block 30 and the second positioning block 40 (see...), Figure 3The first locking block 612 engages with the first locking recess 6311, and the second locking block 622 engages with the second locking recess 6312. This allows the first elastic arm 611 and the second elastic arm 621 to be set to be relatively long, giving them better deformation capabilities.

[0037] like Figures 1 to 3 As shown, the first connecting hole has a first clearance notch 321 on its wall, and the first locking part 61 is disposed within the first clearance notch 321; the second connecting hole 42 has a second clearance notch 421 on its wall, and the second locking part 62 is disposed within the second clearance notch 421. During the insertion and removal of the connecting pin 50, when the position of the connecting pin 50 without the locking recess 631 abuts against the first locking block 612 and the second locking block 622, the first elastic arm 611 and the second elastic arm 621 will undergo elastic deformation, causing the first locking block 612 and the second locking block 622 to move away from the connecting pin 50. The first clearance notch 321 and the second clearance notch 421 can provide space for the movement of the first locking block 612 and the second locking block 622.

[0038] Specifically, in this embodiment, the first positioning block 30 and the second positioning block 40 have the same structure, so the same mold can be used to process the first positioning block 30 and the second positioning block 40, which can effectively reduce production costs. Therefore, the structure of the first positioning block 30 will be described in detail below.

[0039] like Figures 4 to 6 As shown, the first positioning block 30 includes a first main body 34 and a second main body 35. The first main body 34 has a receiving recess 341, and the second main body 35 is disposed within the receiving recess 341. A first groove 342 is provided on the inner wall of the receiving recess 341, and a second groove 351 is provided on the side wall of the second main body 35. The first groove 342 and the second groove 351 are joined to form a first connecting hole. A first clearance notch 321 is provided on the groove wall of the second groove 351, and a first snap-fit ​​part 61 is disposed within the first clearance notch 321. When the first positioning block 30 is assembled onto the first LED housing 10, the first main body 34 is connected to the first LED housing 10, and the second main body 35 is pressed between the first main body 34 and the rear surface of the first LED housing 10, thereby ensuring the tightness of the connection between the first positioning block 30 and the first LED housing. A first groove 342 and a second groove 351 are respectively machined on the first main body 34 and the second main body 35 to form a first connecting hole, which has the advantages of simple structure and easy processing and manufacturing. Specifically, a first positioning post 352 is provided on the second main body 35, and a corresponding positioning hole is provided on the first main body 34, which facilitates the connection between the first main body 34 and the second main body 35. Figures 2 to 6As shown, in this embodiment, the first main body 34 and the second main body 35 are injection molded and configured as hollow thin plate structures. The first clearance notch 321 is provided on the groove wall of the second groove 351, that is, the first snap-fit ​​part 61 is provided in the second groove 351. The first clearance notch 321 is a through-hole structure that penetrates the bottom wall of the second groove 351, which ensures sufficient clearance space. At the same time, it facilitates the processing of the first snap-fit ​​part 61. Of course, in other feasible embodiments, the first clearance notch can also be a long strip blind hole structure or the first clearance notch can also be provided on the groove wall of the first groove.

[0040] In this embodiment, the first main body 34 is a frame-shaped structure with an opening on one side, and the second main body 35 is inserted into the frame-shaped structure from the opening. Of course, in other feasible embodiments, the first positioning block can also be divided into a first main body and a second main body that are vertically aligned (i.e., perpendicular to the front surface of the LED housing) and connected together.

[0041] like Figures 2 to 6 As shown, the first positioning block 30 includes a first main body 34 and a second main body 35. The first main body 34 has a receiving recess 341, and the second main body 35 is disposed within the receiving recess 341. The first positioning block 30 also includes a mounting portion 36 disposed on the first main body 34, with a mounting hole 361. The first positioning block 30 is connected to the first LED housing 10 by fasteners passing through the mounting hole 361. The bottom surfaces of the first main body 34, the second main body 35, and the mounting portion 36 together form a first positioning surface 33. The mounting portion 36 is a raised edge structure located at the lower end of the first main body 34. The first positioning block 30 is connected to the first LED housing 10 by fasteners passing through the mounting hole 361, offering advantages of simple structure and reliable connection. Specifically, the mounting portion 36 is provided with a second positioning post 362, which can be inserted and engaged with the positioning hole located on the first LED housing 10.

[0042] like Figures 2 to 6 As shown, the first positioning surface 33 includes a first positioning surface planar portion 331 extending in a horizontal direction and a first positioning surface inclined portion 332 extending in an oblique direction, which is mainly to adapt to the shape of the back of the first LED housing 10.

[0043] like Figure 2 , Figure 3 , Figure 5 and Figure 7As shown, the side wall of the connecting pin 50 is provided with an anti-detachment groove 51 extending along its length. The first positioning block 30 or the second positioning block 40 is provided with an anti-detachment pin passing through the anti-detachment groove 51. The connecting pin 50 can be connected to the first positioning block 30 or the second positioning block 40. The anti-detachment pin can cooperate with the end wall stop in the length direction of the anti-detachment groove 51 to prevent the connecting pin 50 from detaching from the first positioning block 30 or the second positioning block 40. Through the sliding and limiting cooperation between the anti-detachment pin and the anti-detachment groove 51, the connecting pin 50 can always be located within the first connecting hole, thus eliminating the need for additional consideration of the connecting pin 50's storage and facilitating operator operation. Specifically, the first main body 34 is provided with an anti-detachment pin hole 343. The anti-detachment pin can be a pin inserted into the anti-detachment pin hole 343 and extending downwards out of the anti-detachment pin hole 343.

[0044] Specifically, in this embodiment, the cross-sectional shape of the first connecting hole and the second connecting hole 42 is elliptical, and correspondingly, the cross-sectional shape of the connecting pin 50 is also elliptical. This enables an anti-rotation fit between the connecting pin 50 and the first connecting hole and the second connecting hole 42. Of course, in other feasible embodiments, the cross-sectional shape of the first connecting hole and the second connecting hole can also be other non-circular structures, such as polygons, "D" shapes, etc.

[0045] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, one end of the connecting pin 50 is provided with a handle 52, which extends away from the first positioning surface 33. During the assembly of the LED cabinet, the operator can hold the handle 52 to insert or remove the connecting pin 50 (here, inserting or removing refers to inserting the connecting pin 50 into or pulling it out of the second connecting hole 42), which is convenient. At the same time, the handle 52 extending away from the first positioning surface 33 prevents the operator from inserting the connecting pin 50 backwards.

[0046] like Figure 9 and Figure 10 As shown, this application also provides an LED display device, including a first LED cabinet 10, a second LED cabinet 20, and a positioning component connected between the first LED cabinet 10 and the second LED cabinet 20. The positioning component is the aforementioned positioning component. The aforementioned positioning component can effectively solve the problem in the related art where the assembled LED display device cannot form an ideal plane due to processing, assembly errors, and deformation of the LED cabinet. The LED display device with the aforementioned positioning component also has the aforementioned advantages.
