Description

Technical Field

[0001] The invention relates to a corner protection structure, in particular to a corner protection structure for protecting a display module. Background Art

[0002] With the advancement of technology, the display industry is booming. In addition to displays with borders such as TV screens, there are also borderless LED (light-emitting diode) display modules. This LED display module can be used alone or multiple LED display modules can be assembled to form an LED TV wall. The LED display module includes a fixing and a light board. The light board includes a circuit board disposed on the fixing and a plurality of light beads disposed on the circuit board.

[0003] When manufacturers sell or ship LED display modules, they typically use foam to directly cover the outside of the LED display module and then pack it into a box for shipping or delivery. However, during the transportation of the LED display module, if the box or LED display module is affected by vibration or impact during transportation, the foam can rub against the light board, or cause the light beads in the corners of the light board to become embedded in the foam, causing the light beads to fall off the circuit board. Due to the small size of the light beads, it is difficult to repair or replace them when only one light bead falls off. In addition, if the light bead falls off and damages the solder pads on the circuit board, it will be difficult to install a new light bead in the damaged area, causing the LED light board module to become defective and scrapped, which increases costs. Therefore, it is necessary to improve the current problem of LED light board modules being shipped. If vibration or impact causes the light beads in the corners to fall off, it is difficult to repair and leads to increased costs. Summary of the Invention

[0004] The main purpose of the present invention is to provide a corner protection structure to cooperate with the corner assembly of the display module, which is easy to assemble and can be reused, and has a better protection effect on the lamp beads of the display module. This improves the current problem of transporting the light board module, where if vibration or collision causes the lamp beads located in the corner to fall off, it is difficult to repair and leads to increased costs.

[0005] In order to achieve the aforementioned objectives, the corner protection structure of the present invention includes a frame and at least one protective member, at least one side of the frame is provided for the lamp panel to be assembled, and the protective member is assembled at the corner of the frame along the assembly direction, wherein the corner includes a mating area, the mating area has at least one buckle groove and at least one guide groove extending along the assembly direction; the protective member has at least one clip and at least one slider, the slider corresponds to the guide groove, and the clip corresponds to the buckle groove.

[0006] The corner protection structure of the present invention is applied to a display module. The frame can be used to assemble the light board. The surface of the light board has multiple lamp beads, and the protective member can protect the lamp beads during the transportation of the display module. The corner protection structure has the following advantages:

[0007] 1. It can improve the protection effect: When the display module is hit during transportation, the protective member can be firmly fixed to the frame by buckling the buckle in the buckle groove and assembling the slider in the guide groove without contacting the lamp board. It can also protect the lamp beads located in the corners of the lamp board, thereby effectively preventing the lamp beads from falling off, thereby avoiding the cost of repairing or scrapping the display module.

[0008] 2. The protective member is reusable: The protective member has a buckle and a slider that are assembled in the buckle groove and the guide groove of the matching area. Therefore, when the display module is transported to the destination, the staff can remove the protective member from the frame and reassemble it on another frame with a corresponding matching area, thereby enabling the protective member to be reused, thereby saving costs.

[0036] The features and technical contents of the related patent applications of the present invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the accompanying drawings. Before the detailed description, it should be noted that similar elements are represented by the same numbers.

[0037] The corner protection structure of the present invention includes a frame 10 and at least one protective member 20. At least one side of the frame 10 can be used for assembling a lamp board 30. The protective member 20 is assembled at at least one corner of the frame 10 after sliding along the assembly directions D1 to D3. The material of the protective member 20 is preferably a flexible material or a material with elastic recovery. The lamp board 30 and the frame 10 can be assembled to form a display module. By assembling the protective member 20 at the corners of the frame 10, the corners of the lamp board 30 can be prevented from being hit.

[0038] Since the protective member 20 can be assembled on the frame 10 in three assembly directions D1 to D3, in order to facilitate the explanation of the corner protection structure of the present invention, the X direction, Y direction and Z direction are indicated in the accompanying drawings using the concept of the XYZ coordinate system. Taking the frame 10 as a reference, the side of the frame 10 on which the lamp board 30 is assembled is defined as the front end in the Y direction (or the front end of the frame 10), and the other side of the frame 10 opposite to the lamp board 30 is defined as the rear end in the Y direction (or the rear end of the frame 10).

[0039] In addition, the corner protection structure provides a variety of protective members 20a-20c, sliders 22a-22d and buckles 21a-21e, and corresponding guide grooves 13a-13d and buckle grooves 12a-12c. The protective members 20a-20c can be assembled on the frame 10 along different assembly directions D1-D3, so that the selection can be based on factors such as manufacturing convenience or assembly convenience.

[0040] Figures 1 to 6This is a first preferred embodiment of the corner protection structure of the present invention, which includes a frame 10 and at least one protective member 20a. One side of the frame 10 can be used to assemble the light panel 30. The protective member 20a is assembled at at least one corner of the frame 10 after sliding along the assembly direction D1. More specifically, the protective member 20a is assembled to the frame 10 along the assembly direction D1 parallel to the X-direction. In other words, the two side edges located at the corner of the frame 10 extend along the X-direction and the Z-direction, respectively, and the assembly direction D1 of the protective member 20a is parallel to the extension direction (X-direction) of one of the side edges of the frame 10.

[0041] See also Figures 1 to 8A ~8B, the corner of the frame 10 includes a mating area 11, which has at least one buckle groove 12a and at least one guide groove 13a, 13b extending along the assembly direction D1. The buckle groove 12a is arranged at the end of the guide grooves 13a, 13b at intervals along the assembly direction D1; the protective member 20a has at least one buckle 21a~21c and at least one slider 22a, 22b. The buckles 21a~21c correspond to the buckle groove 12a, and the sliders 22a, 22b correspond to the guide grooves 13a, 13b.

[0042] The protective member 20a can prevent the protective member 20a from falling off along the assembly direction D1 by fastening the buckles 21a~21c to the buckle grooves 12a of the mating area 11. By extending the sliders 22a and 22b into the guide grooves 13a and 13b, the protective member 20a can prevent the protective member 20a from falling off along the other two directions perpendicular to the assembly direction D1. For example, since the assembly direction D1 is along the X direction, the sliders 22a and 22b can prevent the protective member 20a from falling off along the Y direction or the Z direction. In this way, the protective member 20a can be assembled in the mating area 11 of the frame 10 and will not fall off.

[0043] The following will describe in detail the cooperation between the buckles 21a-21c and the buckle slots 12a. Figure 4 As shown, the buckle groove 12a has a first buckle surface 121, and the first buckle surface 121 is perpendicular to the assembly direction D1. Figure 1 and Figure 4 As shown, the buckles 21a-21c have a second engaging surface 211 and a bevel guide portion 212, and the thickness of the bevel guide portion 212 decreases along the assembly direction D1.

[0044] In addition, if Figure 3 and Figure 4 As shown, the matching area 11 is formed with an oblique guide opening 15 at the ends of the guide grooves 13a and 13b. The oblique guide opening 15 can provide a guiding effect for the buckles 21a to 21c when assembling the protective member 20a, thereby improving the convenience of assembly.

[0045] When the protective member 20a is assembled to the mating area 11 of the frame 10, the clips 21a~21c enter the space of the guide grooves 13a and 13b. Then, the guide bevel portions 212 of the clips 21a~21c are fitted on the guide bevel openings 15 and slide to the ends of the guide grooves 13a and 13b, and leave the space of the guide grooves 13a and 13b until the clips 21a~21c are buckled into the corresponding buckle grooves 12a. The first buckle surface 121 of the buckle groove 12a and the second buckle surface 211 of the clips 21a~21c abut against each other to ensure that the protective member 20a is limited relative to the frame 10.

[0046] Among them, such as Figure 1 and Figures 7A-7B As shown, the second buckle surface 211 of the buckle 21a may be rectangular; or the second buckle surface 211 of the buckle 21b may be trapezoidal; or the second buckle surface 211 of the buckle 21c may be semicircular.

[0047] The structure of the protective member 20a is described in detail below. Figure 1 、 Figure 2 and Figure 4 As shown, the protective member 20a includes a first substrate 23 and a second substrate 24. There is an angle between the first substrate 23 and the second substrate 24. Generally speaking, the angle matches the angle at the corner of the frame 10. Preferably, the angle can be slightly smaller or slightly larger than the angle at the corner of the frame 10, and the flexibility of the protective member 20a is utilized to improve the tight fit between the two.

[0048] In addition, if Figure 1 and Figure 5 As shown, the protective member 20a has a protective wall 201, which extends from the corner of the frame 10 along the Y direction and protrudes beyond the lamp board 30. The protective wall 201 has a height H relative to the lamp board 30 on the frame 10 in the Y direction, which can ensure that the lamp beads on the lamp board 30 are not easily affected by collision, extrusion, and fall off or damage.

[0049] Furthermore, the latches 21a-21c and the sliders 22a and 22b are located on the surface of the first substrate 23 facing the frame 10. The surface of the second substrate 24 facing the frame 10 is formed with a protrusion 25. The mating area 11 of the frame 10 has a recess 14 corresponding to the protrusion 25. The interplay of the protrusion 25 and the recess 14 allows the protective member 20a to be positioned relative to the frame 10 in the Y or Z direction, thereby enhancing the positional retention between the protective member 20a and the frame 10. Furthermore, a removal flange 231 is formed on the edge of the first substrate 23 in the assembly direction D1. This design facilitates the operator's removal of the protective member 20a from the frame 10.

[0050] The following describes in detail the structure of the sliders 22a and 22b. Figure 5 and Figures 8A-8B As shown, the sliders 22a and 22b have a base 221 and a limiting protrusion 222 connected to the base 221 . The limiting protrusion 222 is located in the Z direction of the base 221 , and the width of the limiting protrusion 222 is greater than the width of the base 221 .

[0051] Among them, such as Figure 1 and Figure 5 As shown, the slider 22a is formed into a dovetail structure, the width of the limiting protrusion 222 of the slider 22a and the width of the base 221 gradually increase along the Z direction, and the guide groove 13a is formed into a dovetail groove that matches the slider 22a; Figures 8A-8B As shown, the width of the limiting protrusion 222 of the slider 22b and the width of the base 221 form a step difference along the Z direction, and the guide groove 13b is formed to match the step difference structure of the slider 22b. In addition, the sliders 22a and 22b can also be a single-sided dovetail structure, that is, one side of the limiting protrusion 222 of the sliders 22a and 22b extends in the Y direction, and the guide grooves 13a and 13b are single-sided dovetail grooves that match the sliders 22a and 22b (please refer to Figure 21 Whether it is the slider 22a or the slider 22b, both can ensure that the protection member 20a is limited relative to the frame body 10 in the non-assembly direction D1.

[0052] Next, the assembly of the protective member 20a will be described by taking the first preferred embodiment of the corner protection structure of the present invention as an example. Figure 4 As shown, the staff can hold the frame 10 and the protective member 20a separately, and place the protective member 20a at the rear end of the frame 10 in the X direction, then align the buckle 21a and the slider 22a of the protective member 20a with the guide groove 13a along the X direction, and then extend the buckle 21a and the slider 22a into the guide groove 13a along the X direction. After the buckle 21a is buckled into the buckle groove 12a, the protective member 20a is set on the matching area 11 of the frame 10, as shown in FIG. Figure 6 As shown, the matching areas 11 at the corners around the frame 10 can each be used to assemble a protective member 20a.

[0053] Among them, the design of the guide portion 212 of the clip 21a can reduce the resistance caused by the clip 21a during assembly, and can make it easy for the staff to push the protective member 20a into the mating area 11 along the assembly direction D1. Combined with the design of the guide opening 15 of the mating area 11, the resistance to assembling the protective member 20a can be further reduced, thereby effectively improving the convenience of assembly.

[0054] like Figure 4As shown, the second buckle surface 211 of the buckle 21a and the first buckle surface 121 of the buckle groove 12 can abut against each other, thereby preventing the protective member 20a from falling off along the X direction; Figure 5 As shown, the slider 22a cooperates with the guide groove 13a to limit the protective member 20a in the Y direction, and the limiting protrusion 222 of the slider 22a cooperates with the guide groove 13a to limit the protective member 20a in the Z direction. The protrusion 25 on the second substrate 24 cooperates with the recess 14 to assist the protective member 20a in limiting the Y and Z directions, thereby effectively fixing the protective member 20a and preventing the protective member 20a from falling off due to impact.

[0055] After the display module is transported to the destination, the staff can pull the first substrate 23 away from the frame 10, so that the buckle 21a disengages from the buckle groove 12a, and push the protective member 20a along the assembly direction D1 to disengage the slider 22a from the guide groove 13a, and then remove the protective member 20a. Among them, the disassembly flange 231 of the first substrate 23 can facilitate the staff to pull the first substrate 23, thereby improving the convenience of removing the protective member 20a.

[0056] Please refer to Figures 9 to Figure 15 , which is a second preferred embodiment of the corner protection structure of the present invention, wherein the assembly direction D2 moves along the Y direction. In more detail, the frame 10 has a lamp board assembly area 101 on one side of the front end in the Y direction, and the lamp board 30 is assembled in the lamp board assembly area 101 of the frame 10. The assembly direction D2 moves from the lamp board assembly area 101 toward the other side of the frame 10 opposite to the light board assembly area 101. In this embodiment, the protective member 20b is assembled in the frame 10 along the assembly direction D2 parallel to the Y direction, and the assembly direction D2 of the protective member 20b moves from the front end in the Y direction to the rear end in the Y direction.

[0057] like Figure 9B 、 Figure 10B and Figure 14 As shown, the mating area 11 at a corner of the frame 10 has at least one buckle groove 12b and at least one guide groove 13c extending along the assembly direction D2.

[0058] like Figure 9A 、 Figure 10A 、 Figure 11 and Figure 15As shown, the protective member 20b has at least one buckle 21d and at least one slider 22c arranged at intervals along the Y direction, the slider 22c corresponds to the guide groove 13c, and the buckle 21d corresponds to the buckle groove 12b, so as to achieve the limitation of the protective member 20b relative to the frame 10 in the Y direction, and the slider 22c has a base 221 and a limiting protrusion 222 connected to the base 221, the width of the limiting protrusion 222 is greater than the width of the base 221, thereby making the slider 22c have a dovetail design, which can prevent the protective member 20a from falling off along the other two directions perpendicular to the assembly direction D2 (i.e., the X direction and the Z direction). In addition, the protective member 20b has a protective wall 201, which extends from the corner of the frame 10 toward the side of the frame 10 (for example, the Y direction) where the lamp board 30 is assembled, and protrudes beyond the lamp board 30. The protective wall 201 has a height H relative to the lamp board 30 on the frame 10 in the Y direction, which can ensure that the lamp beads on the lamp board 30 are not easily affected by collision, squeezing, falling off or damage.

[0059] like Figures 9A-9B and Figures 10A-10B As shown, the protection member 20 b includes a first substrate 23 and a second substrate 24 . An angle is formed between the first substrate 23 and the second substrate 24 , and the angle matches the angle of the corner of the frame 10 .

[0060] In the first embodiment of the protective member 20b of this embodiment, as shown in FIG. Figures 9A-9B As shown, the buckle 21d and the slider 22c in the protective member 20b are arranged at intervals along the Y direction. The number of the buckle 21d and the slider 22c is a group, and the slider 22c and the buckle 21d are both provided on the first substrate 23. The base 221 of the slider 22c is connected to the first substrate 23. The slider 22c corresponds to the guide groove 13c. The protective member 20b can be limited in the X direction and the Z direction with the help of the slider 22c, and is arranged at intervals with the slider 22c along the Y direction with the help of the buckle 21d to ensure that the protective member 20b will not fall out in the Y direction.

[0061] In the second embodiment of the protective member 20b, as shown in FIG. Figures 10A-10B As shown, the number of the buckle 21d and the slider 22c is a group, and the slider 22c is arranged on the first substrate 23, and the buckle 21d is arranged on the second substrate 24, and the slider 22c and the buckle 21d can also achieve the effect of limiting the protective member 20b.

[0062] Moreover, if Figures 11 to 14As shown, in the third implementation of the protective member 20b of this embodiment, the protective member 20b includes two substrates 26, and the number of the clips 21d and the sliders 22c is two groups, and one group of clips 21d and the sliders 22c are respectively provided on the two substrates 26. This ensures that the protective member 20b can be firmly combined with the matching area 11 of the frame 10, thereby improving the assembly stability of the protective member 20b.

[0063] It should be noted that the buckle 21d is disposed on the edge of the first substrate 23, the second substrate 24 or the substrate 26 to increase the travel of the guiding groove 13c.

[0064] In addition, if Figure 9B 、 Figure 10B 、 Figures 14 to 17 As shown, the guide groove 13c is sequentially defined by an entry section 131 and a guide section 132 along the assembly direction D2. The width of the entry section 131 corresponds to the width of the limiting protrusion 222, and the guide section 132 cooperates with the slider 22c.

[0065] like Figures 15 to 17 As shown, when the protective member 20b is assembled to the mating area 11 of the frame 10, the limiting protrusion 222 of the slider 22c enters the guide groove 13c through the entry section 131, and the slider 22c then slides into the guide section 132, and the buckle 21d will abut against the surface of the frame 10 and slide to the end of the guide groove 13c, and use the elasticity of the protective member 20b itself to buckle into the buckle groove 12b, thereby ensuring that the protective member 20b is limited relative to the frame 10.

[0066] When removing the protective member 20b from the frame 10, the worker can directly pull the buckle 21d located on the edge of the frame 10 to disengage the buckle 21d from the buckle groove 12b. Then, the worker can push the slider 22c away from the guide groove 13c along the assembly direction D2, and the protective member 20b can be separated from the mating area 11 of the frame 10. More specifically, the assembly direction D2 of the second preferred embodiment of the present invention moves from the lamp board assembly area 101 toward the other side of the frame opposite the lamp board assembly area 101. When removing the protective member 20b, the worker can insert a jig between the buckle 21d and the buckle groove 12b. This removal operation is performed behind the lamp board assembly area 101, thereby reducing the risk of the worker knocking off the lamp beads during removal.

[0067] See also Figures 18 to 22, which is a third preferred embodiment of the corner protection structure of the present invention, wherein the assembly direction D3 is along the Y direction, the frame 10 has a lamp board assembly area 101, the lamp board 30 is assembled in the lamp board assembly area 101 of the frame 10, and the assembly direction D3 moves from the other side of the frame 10 opposite to the light board assembly area 101 toward the light board assembly area 101. In this embodiment, the light board assembly area 101 is provided at the front end of the frame 10 along the Y direction, and the protective member 20c is assembled in the frame 10 along the assembly direction D3 parallel to the Y direction, and moves from the rear end along the Y direction to the front end in the Y direction.

[0068] like Figure 20 As shown, the corner includes a mating area 11 having at least one locking groove 12c and at least one guide groove 13d extending along the assembly direction D3. The guide groove 13d extends along the Y direction, allowing the protective member 20c to slide along the space within the guide groove 13d in the Y direction. It should be noted that the mating area 11 also includes an oblique guide opening 15, which is spaced apart from the locking groove 12c along the assembly direction D3.

[0069] like Figure 18 and Figure 19 As shown, the protective member 20c includes at least one base plate 26, which has at least one latch 21e and at least one slider 22d. The latch 21e is disposed on the edge of the base plate 26, and the slider 22d is disposed on the surface of the base plate 26. The slider 22d corresponds to the guide groove 13d, and the latch 21e corresponds to the latch groove 12c, thereby limiting the position of the protective member 20c relative to the frame 10. Furthermore, the protective member 20c has a protective wall 201. The protective wall 201 extends from a corner of the frame 10 toward a side (e.g., in the Y direction) where the lamp board 30 is assembled to the frame 10, and protrudes beyond the lamp board 30. The protective wall 201 has a height H relative to the lamp board 30 on the frame 10 in the Y direction. This ensures that the lamp beads on the lamp board 30 are not easily knocked off or damaged by collision or squeezing.

[0070] like Figure 18 and Figures 20 to 22 As shown, the buckle groove 12c defines a first buckle surface 121 perpendicular to the assembly direction D3. Figure 22 As shown, the buckle 21e has a second buckling surface 211 and a guide bevel portion 212, and the thickness of the guide bevel portion 212 decreases along the assembly direction D3, wherein the second buckling surface 211 of the buckle 21e can be rectangular, or the second buckling surface 211 of the buckle 21e can also be semicircular (not shown). In addition, when the buckle 21e is buckled into the corresponding buckle groove 12c, the first buckle surface 121 of the buckle groove 12c can abut against the second buckle surface 211 of the buckle 21e.

[0071] like Figure 19 、 Figure 21 and Figure 22As shown, the slider 22d defines a stop section 223 and an extension section 224 along the assembly direction D3. The stop section 223 extends laterally to form a stop flange 225. Furthermore, the guide groove 13d defines an entry section 131 and a guide section 132 along the assembly direction D3. The width of the entry section 131 corresponds to the width of the stop flange 225 of the stop section 223. The guide section 132 cooperates with the extension section 224 of the slider 22d. The stop flange 225 of the stop section 223 and the entry section 131 of the guide groove 13d cooperate to achieve positioning of the protective member 20c in the X and Z directions.

[0072] like Figure 21 As shown, the extension section 224 of the slider 22d has a base 221 and a limiting protrusion 222 connected to the base 221. The width of the limiting protrusion 222 is greater than the width of the base 221. The base 221 is connected to the substrate 26. Specifically, on the slider 22d connected to the substrate 26 perpendicular to the Z direction, the limiting protrusion 222 extends along the X direction; on the slider 22d connected to the substrate 26 perpendicular to the X direction, the limiting protrusion 222 extends along the Z direction.

[0073] That is to say, when the protective member 20a is assembled in the matching area 11 of the frame 10, the slider 22d of the protective member 20c will slide along the assembly direction D3, and the buckle 21e will slide in contact with the guide bevel 15 until the buckle 21e is buckled into the corresponding buckle groove 12c. The first buckle surface 121 of the buckle groove 12c and the second buckle surface 211 of the buckle 21e abut against each other to ensure that the protective member 20c is limited relative to the frame 10 in the Y direction, and the extension section 224 and the limiting protrusion 222 of the slider 22d can cooperate with the guide section 132 of the guide groove 13d to achieve the limitation of the protective member 20c in the X direction and the Z direction.

[0074] After the display module is delivered to the destination, the staff can pull the protective wall 201 of the protective member 20c to disengage the buckle 21e from the buckle groove 12c, and push the protective member 20c along the assembly direction D3 to disengage the guide groove 13d, thereby removing the protective member 20c.

[0075] Among them, the light board 30 can be assembled to the frame 10 before the protective parts 20a and 20c are assembled to the frame 10, or can be assembled to the frame 10 after the protective parts 20a and 20c are assembled to the frame 10. When the display module is hit by external force during transportation, the protective wall 201 of the protective parts 20a~20c can prevent the corners of the light board 30 from being hit, and there is a distance between the protective wall 201 and the light board 30, thereby preventing the protective parts 20a~20c from contacting the light board 30 and transmitting the impact force.

[0076] In addition, the protective members 20a-20c are designed to be reusable. After the staff removes the protective members 20a-20c, they can be reassembled on another frame 10 having a corresponding matching area 11, thereby reducing costs.

[0077] In summary, the frame 10 of the corner protection structure of the present invention can be assembled with the lamp board 30, and the protective parts 20a~20c are assembled with the corresponding buckles 21a~21e and sliders 22a~22d and the buckle grooves 12a~12c and guide grooves 13a~13d of the matching area 11, so that the protective parts 20a~20c can be firmly set in the matching area 11 of the frame 10 during the transportation of the display module without falling off, and can protect the lamp beads near the corners of the lamp board 30, thereby avoiding the cost of repairing or scrapping the display module.

[0078] Although the embodiments of the present invention have been disclosed above, they are not intended to limit the present invention. Any technician in the field should be able to make some changes and modifications without departing from the spirit and scope of the embodiments of the present invention. Therefore, the scope of protection of the embodiments of the present invention should be based on the attached claims.
